Question Going insane trying to edit APN Settings - Xiaomi Mix Fold 2

If I try to edit an existing APN it will no let me all the options are grayed out
If I try to add a new APN it says that it saves but its nowhere listed. I changed carriers and this is driving me nuts. Any ideas or similar problems?
EDIT - finally got it. no idea why but if you have the wrong number for the one setting (which was provided by the company) it won't save. finally found a reddit thread with the fix

do you have VoLTE with your new carrier?

Yes, VoLTE has never been a problem. I've had an absolute nightmare switching providers though all because of using a Xiaomi phone
I have always used month to month cell providers because I never know what device I want to get and don't want to be locked into a carrier that won't work as well depending on my device.
anyways, I had been using Straight Talk in the US because what was great about straight talk is you could pick the sim you wanted and use any towers AT&T (gsm), Sprint/Verizon (cdma), Tmobile (Gsm)
I had been using straigh talk with AT&T towers for years. The mix fold worked fine on it.
I saw that AT&T was offering a full year of service with 16gb per moth on their prepaid plan for $300. great deal I thought. I was already using the mix fold 2 on AT&T towers with no problems.....so I thought.
so I order the AT&T service, to do this you have to start porting your number and I do that. Well, once I get the sim it will not activate. I come to find out that AT&T will not activate any Xiaomi devices on their network. I thought no problem, just activate it on another phone and then put the sim in the mix fold 2. That will not work either, the entire account is based on IMEI and it won't work in another phone according to everyone on reddit, etc. So my phone number that I started porting never completed because I could not activate the sim. So ATT sends my phone number port back to straight talk. straight talk claims the number is gone they ported it out.
its an absolute nightmare. after a few days Straight Talk finally figures out they do have my number but they tell me in order to get it on my account again I have to activate a new straight talk sim. straight talk was recently just bought by verizon. so I can only activate a straight talk verizon sim to get my number working. Verizon ties everything to IMEI as well. None of the 5 or so phones I have will work to activate cause they are all gsm only. I ended up having to borrow a friends verizon phone to get a sim activated and the number back in my account to then port it out to Mint Mobile that users Tmobile towers. It was an absolute nightmare and took hours on the phone with clueless CSRs all because I want to use this mix fold 2 phone.
anyways, Tmobile pretty much sucks for data speeds but I am done. I'll live with it. I've never seen it connect to 5G. I have seen LTE+. I can't figure out if its so bad because of the phone or if tmobile just sucks that much in this area. I might go to the tmobile store to see if the acual tmobile is better and if they are nerfing the mvno prodivers.
anyways, from what I can see if you want to use the Mix Fold 2 in the USA you have to use Tmobile towers. none of the AT&T mvno's like Boost mobile will let you use xiaomi it seems, but i'm not completely sure either.

I have always been an Android man because all of my forensics training, etc, has been on Android, but I will admit that iPhones have one big advantage - they work on any network anywhere. I realized a couple of weeks ago with the Xiaomi that just because your carrier allows VoLTE doesn't mean they allow VoLTE Roaming. I travelled from Nova Scotia to Colorado and although I was connected there to T-Mobile towers, I had no VoLTE and couldn't place voice calls. I happened to put a friend's SIM into my device in Denver - and bang, instant VoLTE. I put my Canadian SIM back in (which gives me VoLTE at home) and no VoLTE. Although more and more carriers are provisioning VoLTE for the device, very few have provisioned VoLTE Roaming. Android needs to get its act together, and stand up to the carriers like Apple does.

[Q] Getting LTE on AT&T w/ Nexus 5

Hello,
I'm coming from a Nexus 4, and have never had an LTE phone on my AT&T account before. I've read that since AT&T doesn't have Nexus 5 in their system, that it will be a hassle for them to activate LTE through the phone. I can't really find any concrete answers or info, so I figured I'd stop by here and see if anyone has any ideas?
Does AT&T have to activate LTE on their end for it to work? Or can I just adjust my APN once I get the phone?
Has anyone had any issues with this at all? How did you get around it?
Thanks in advance!
I would like to know too... Im thinking about switching over my corporate account from VZW to ATT and I ordered a Nexus 5 to try out ATT coverage in my area first. I was going to head into the ATT store tomorrow, now Im worried I won't be able to get it setup (Im not familiar with how ATT works). Do I need to get a IMEI from a phone in the store and give to them? I don't get my N5 until tomorrow night and I was planning on going the store tomorrow morning and getting either Gophone or shared plan SIM setup so I can pop it in when the phone arrives. Will they need an IMEI to even get me an account activated?
If they need an IMEI at activation, would it matter if I didn't have the device in front of me, like if I tell them I ordered a S4 and gave them a IMEI from one? Do I need to find someone on ATT to give me their IMEI and tell them at the store I have it ordered? Sorry if these request are way off based on how it actually works, but I want to be able to test out my N5 tomorrow night! Thanks for any help you can give me..
EDIT: In the ATT world, would It be considered shady for me to tell them all this info? For instance if I told the salesmen this problem and asked if they could use an IMEI off one of their phones?

I'm assuming that this will work similar to how it worked for the N4 and enabling HSPA+ on AT&T.
You will need an LTE plan added to your account. It won't cost more, but the account needs to enable the LTE service. In order to do this, I believe AT&T will need an IMEI. Since the IMEI will not be recognized, then you need to get another AT&T LTE device's IMEI code. Maybe a friend? I know some people would copy it off a demo device in the store.
Good luck.
FWIW: I put my LTE sim in the phone and everything was autoenabled correctly. This was better than with the N4 where it autoenabled wrong, and I had to change the settings.
I'll clarify this, AT&T has different data plans. They have all their data plans for 3g phone (3g data unlimited), and all their 4g data plans. You can not get 4g unless your data plan has been switched to the 4g version. You can keep your unlimited plans with this. Just call and ask them to switch your data plan to the lte version.
Sorry double post

So, to clarify, did you just activate LTE with an N5 coming from an N4 and it went smoothly?

i'm in the same boat, i'll know for sure when i get the n5 tomorrow but from what i've seen AT&T does have to provision your SIM for LTE. My plan is to goto an AT&T store and ask them if they can get my sim sorted; if they screw around or say they "can't" help me then i'll either grab an imei from one of the demo phones or from a buddy and call them and give them that.

This looks to be the thing to do. I just had someone inform me that they brought the phone into AT&T, and the guy punched in the numbers off the sticker on the back, gave him a sim and he was good to go. I'll make sure to come back here and report my own findings first hand since this question seems to be floating around a bit.

I've read imei's are never checked
I already had an LTE Sim. I just used the LTE Sim in my n4.

College Station, November 4, 2013 Verified - LTE addon
I can verify coming from a "Nexus S" BYOD.
I went to an AT&T Store in College Station, TX to get a new microSIM because the Nexus 5 only takes microSIM form factor.
I then got an LTE signal, but no IP address.
Chatted online and they told me to wait 1 hour then reboot the phone. Did so.. same response, gets on the LTE network fast, but nevers gets an IP address.
So I then called 611 on the Nexus 5 and talked to Tech Support, told them:
1. I have never had an LTE phone before and thought I needed LTE service added to my Account Profile.
2. I wanted "No changed to my legacy Unlimited plan"
They told me
1. My "legacy Unlimited plan had just been removed by 'mistake' and would have to be restored by the (backoffice)"
2. They were updating my account to enable LTE service
I then had to reboot the phone, did so and the Internet service came right up.
Now I have to wait up to 72 hours for AT&T backoffice to confirm they have restored my Unlimited plan.
I put a pass-code on my Account, and strenuously stress every time.. DO NOT TOUCH MY UNLIMITED PLAN !!!! -- And they do it any way.
.. exasperated ...
They also do not know what a "Nexus 5" phone is yet.. so I think only the call in Tech Support can interpolate what to do. I think the kee was to keep calling it an "LTE enabled Nexus 4" and then things just "worked".

THE AT&T DATA THREAD: The Answer to getting LTE working on your N5

IF YOU HAVE ACCESS TO LTE ON AN AT&T PHONE, YOU DONT HAVE TO DO ANYTHING!!!!!!!!
IF YOU ALREADY HAVE A SIM CARD THAT WILL FIT IN THE N5, YOUR SIM IS LTE CAPABLE AND ALL YOU HAVE TO DO IS GET THE RIGHT DATA PROVISION. YOU DO NOT NEED TO GET A NEW SIM!!!!!!!
This happened when the N4 came out and I came to the rescue far too many times to count...and I've already started to read threads about it so here we go!
You just bought an N5 and are either worried about getting LTE or can't get LTE connectivity on your N5. It's a really big issue with a really simple solution. You need to make sure of a few things.
1. You have a SIM that can receive LTE frequency
2. Your data plan is a LTE provisioned plan
3. Your APNs include an LTE ANP
1 & 2 can be solved at the same time and 3 should solve itself in most cases.
Here's the big issue: AT&T doesn't have a data provision for the N5 (or the N4). Your customer service rep will take the IMEI number from your phone when you ask for a new SIM and it will come back with their basic GSM plan by default. This caused awful data speeds on the N4 and will disallow LTE on the N5 so you need to inform them that this will happen before they go through the process. A nice rep will understand. An unknowledgeable rep will claim there is nothing they can do. Ask to speak to the manager. If none of them can help, take your new LTE capable SIM and walk away.
Now after you leave the store call up customer service and tell them you just got a new *insert LTE capable AT&T device here* and you can't find the IMEI number. Tell them you tried to go into the store and they were unhelpful so you're calling. The person will immediately become helpful and generate an IMEI number. They will provision your data using said serial number and you'll be good to go.
BEFORE inserting your SIM, start up your N5. Go through the setup process that you have to go through and then turn it back off. Plug in your SIM and reboot.
Go to Settings > Wireless & Networks > more > Mobile Networks > Access point Names. In there you should see an AT&T LTE APN and it should be already selected. If not, select it. This should be all you need to do. It really is that simple.
NOTES:
- All SIMs that fit in the N4 and N5 are LTE capable
- Here is what your AT&T APN should look like
- If you have any issues, post and I'll do my best to help
As always, Thanks are appreciated.
So even if the rep in store "can't help" I'll still walk out with the SIM card I need? Also, If I don't have my N5/IMEI in hand when I go in can I still setup a plan and get a SIM card? Thanks for the post!
EDIT: Going in with no phone I don't know rather to tell them I have a N5 coming or try to find a friends that will give me their IMEI that I can give them...
You'll get a SIM card no matter what because those are free...it just won't be provisioned properly unless you get a knowledgeable rep.
Having an IMEI in hand makes life easier; having your N5 will make it way easier. The SIM needs to be activated in the store and they will need an IMEI to activate. Just wait till you get your N5 to go through all this. It won't do anything to help you until you get it.
The IMEI will be on the SIM tray!

Ok, I will wait until Wednesday to go in then...one last thing, if it gets to the point I have to call ATT, when I say I can't find the IMEI won't they just tell me to flip the phone over or look in the settings, etc.. instead of generating one?
No.
They will ask you if there is a barcode / serial thing on the back of your device. You say no. Boom, done.
edit: don't forget to hit the thanks button!
So just going in and asking to exchange your sim for a micro sim isn't enough?
I have a note 3 right now with 4g. I was going to use the same Sim card in the note and put in the N5. Should it work out of the box or do I still have to take it in the store? How will I know that I have a an imei card?

No. The SIM must be activated and an IMEI is required to activate.

Do you have a SIM that will fit in the N5? If not, follow my steps. If so, skip ahead to calling AT&T customer support because ALL MICRO SIMS ARE LTE CAPABLE.
What do you mean by an IMEI card? All phones come with an IMEI.
great. AT&T why are you so terrible.
Im sim is in the note 3 rught now. Sending it back to att. Getting the n5 tomorrow. New to the Sim card thing. Coming from sprint. Just had to ask.

Hey guys I'm going to switching to straight talk att am I ordered the lte micro sim from them and plan to activate tomorrow should I expect to jump through hoops to get lte or expect the same issues as att users...not sure this is my first try at prepaid
same things will happen. You'll need to get an LTE data provision but will be unable to using your N5 IMEI

If you have 4g on your note 3 it means you already have a LTE data plan. All you need to do is take the sim out of your note 3 and pop it into your n5, no need to call anyone or make an unnecessary trip to the store.
4g =/= LTE in AT&Ts case. 4g can mean HSPA+ 4g!
If you have access to LTE currently YOU DO NOT NEED TO DO ANYTHING.

If you have a device and you can't find the IMEI, just go to the settings and about device to view it.. Wouldn't they ask you to do that?
Look, I know you want to dumb down stuff and give advise but some of it is just incorrect, not dumbed down.
Dial *#06# on any Android smartphone and it'll display the IMEI.

It's possible that the reps @ the AT&T Stores in different areas aren't properly keying the IMEI in properly. If at all possible have them SCAN the IMEI barcode on the back of the phone.
I went down to the AT&T store here locally (Bay Area, CA) and the only problem I had in the process was a 30 minute wait to see one of the reps.
I was previously on an unlimited data plan that I've had setup since I got my original iPhone 3G - 5 years ago. NOT an LTE plan by any stretch.
He went in the back and grabbed the sim and started the process of adding it to the account.
He scanned the sim and then scanned my phone -- It CORRECTLY recognized the device as a D820 **AND** automatically updated my data plan to the LTE Unlimited.
The only thing the rep had to do was press confirm a number of times. Not once did he have to manually adjust anything.
We waited about 5 minutes for the sim to activate, slipped it into my N5 and powered it up - Instant LTE service.
So AT&T *does* have the IMEI Registered for the N5 with a corresponding LTE Plan. If someone is trying to key it in and getting an error.. they're likely not typing something correctly.
I'm already using a note 3 on at&t with LTE already enabled on my plan. Also,my note 3 already uses a micro-SIM. I should be good to just swap my SIM into the n5 right? I have written down the default AT&T APN just in case it gets list on the n5.

[Q] Bad IMEI

So I am looking to buy a new phone. I am looking on ebay and there are TONS of bad imei phones for at&t! I want to buy one since they are cheaper. Only issue is that I want to be sure that they will work on straight talk, since that is my current carrier. I have read lots of people's pinions about if they will work or not because of blacklists, and I don't know if there is any one steady answer. I am hoping to get someone with some real knowledge to shed some light on this because I am stumped on if I should take the risk and buy one.
I did call straight talk today and ask if I can bring a phone with a bad IMEI number over and the response I got was strange... They said that all I have to do is buy a BYOP package and give them my sim card number and it will work. I said I know that it will work because i am on a BYOP already, but I wanted to know if my sim would get kicked off for using a blacklisted phone on the at&t network even though it was through straight talk. She said, that they only need the digits from the straight talk sim and it would work. So I tried one more time and explained everything fully... I again received the same response that they needed the sim card numbers only. So I said, does that mean that the IMEI doesn't matter for your service at all and I can have a blacklisted phone on it? and again the response was, (besically) yes, you just need a straight talk sim.
So all in all I understand that to mean that AT&T has nothing to do with straight talk when it comes to blacklisting phones! That's a wonderful thing since there are so many blacklist phones out there right now, but I was hoping someone else could drop a little knowledge on me if they knew something about it, or if they knew that straight talk was lying, so I don't waste my time/money on this phone.
I haven't looked into this since last year, but the FCC was advising on a shared blacklist to be implemented in the future back then.
Also beware that the phone might be stolen, which could lead to more problems in the future.
I've never used Straight Talk, but if they use AT&T towers maybe call AT&T. Honestly, it might be hard to get a real answer from them because most of the reps (true for all companies) don't have a clue how their own blacklists even work - heck, some don't even seem to know they *exist*.
They might not be "lying", it just might not be part of their training is information base.

StraightTalk SIM cards can either use AT&T or T-mobile (Tracfone {parent company for StraghtTalk} leases several carrier's networks). If you buy and AT&T phone with a bad ESN and put a StraghtTalk AT&T SIM into it, the likelihood of it working is low. The reason for this is the you would still be using AT&T's network, and the ESN has a high chance of being picked up by AT&T's black-list.
If I were you, I'd get a factory unlocked phone, or a newer Verizon 4G LTE phone that has a bad (or clean) ESN. The reason I say the later is that most Verizon 4G LTE phones are also world phones and work with GSM. Now, you'll have to remove the radio band block, but that's very easy, and I know XDA has several tutorials for this. I removed the block on my RAZR M and it works just fine with an AT&T SIM inserted.

And if my number is not tied to my imei number then it would be impossible for them to find it out. Or at least i would think it is. Every other service that is tied to an esn or imei number, you have to tell them the number and let them register it. With straight talk you register the sim and can use that sim in any unlocked phone.
I am currently running a note 2 from verizon on straight talk. It is a world phone but i cant seem to get 4g on it. Is this because i have to unlock the bands? If so, how do i do that? I thought it was just because of the apn i was using. I tried a bunch but only got one to work on h+/h/3g (it flickers).

You're half-right. You don't have to give StrraightTalk you ESN (MEID/IMEI). The problem comes when you connect to the network. When you connect, your device will be identified by it's ICCID (SIM #) and it's ESN (so it knows what type of device it is and what service it needs). Because it would be an old AT&T phone, reconnecting to AT&T, there's a high chance it will be matched on the black-list.
As for your Note II, if it's already working, the radio it has may not support the higher GSM 4G/LTE bands. You may be able to unlock them, but I wouldn't know how with a Samsung device. The APN may help, but I'd first check the radio.
Ok I have a question so I have a T-Mobile contract and iPhone 7 Plus for a little over a. Year now but I haven’t paid it off in full and my bill got out of hand so I can’t afford to pay the balance so is there anyway I can use this for any prepaid plans of any company

[Q] OPO on T-Mobile - 2nd OPO, same problem - network connection issue

Hello all,
Back again.
I'm trying to get my "2nd" OPO to work on T-Mobile USA.
First of all, it is not a SIM issue. I have 2 microSIMs that can be used freely across all T-Mobile enabled devices.
Once I try to connect to T-Mobile, it gives me a "Your SIM card doesn't allow connection to this network".
I tried the 'unlock the basebands/LTE process', got as far as ADB talk, but I cannot execute the su command, so the setprop does not work.
And this is my 2nd phone, a replacement from OPO. 2nd month running already. The 1st one had the same issue, but at the time I did not do research on tinkering with it,
and was 'NAIVELY' believing in OPO's customer 'service'.
Took me 2 weeks just to get 2 basic replies of "tech support", which didn't help since they gave me rather weak tech suggestions - 1st suggestion was reset, 2nd suggestion
was to look at the T-Mobile thread (I cannot connect to network, so how do you expect me to connect to APN?!?) . Then took them 3 weeks to go through the RMA process,
and yet another 2 weeks to send me a replacement(not).
Any assistance appreciated.
Check your imei on the tmo compatibility site. It could be blocked. Dumber things have happened. Double check that the SIM is installed properly. Second replacement and multiple sims seems to point at something you are doing.

Thank you for your response!
Yes, the IMEI is not recognized on t-mobile. Which is stupid since this is the second one (the 1st one had the same issue too).
Has anyone else gone through this frustrating experience? To have two OPOs whose IMEIs are not recognized is...... well.... $!%#!. :silly:
SIM installations are fine. I have done them multiple times, with the same results.

Future reference no need to create a new thread to ask the same question as before. You should of just continued your first thread so others would know what you have been going through and what was done to try and fix it. Glad you got it sorted or did you....

Got it.
Unfortunately no. Second OPO, same issues again. IMEI is not supported either. So, Groundhog Day here.
I'm with you man. I left vzw for T-Mobile and struggled like hell with getting the OPO working properly on it. From loaner phones to multiple sims, they/we tried everything. End result was to leave for at& . The signal is strong, but yet I keep missing calls daily. This beauty is going up on eBay. I just can't take it anymore. Sucks because Dev involvement is Huge here
Register and activate your phone with T-Mobile... I had the same issues for MetroPCS, and that fixed it.

I dont have any issues with network on Tmo, but what do u mean by register and activate ?
What I am saying is, you need to contact your carrier and get your IMEI entered into their system in order for the phone to run all services correctly on your carrier... whether it be T-Mobile or anybody else.
My 1+1 ran most of the services and operated on my SIM card and phone number in my hometown area. But, when I went to another area or town, it would not register with or run on any carrier... NONE! not even roaming like it does at home. I had to go to MetroPCS (on T-Mo network) and get my phone activated onto their system for it to run data, and 4G LTE. By just inserting the SIM card does not automatically sign your phone into the system and you should call or go to a dealer store and get it turned onto your particular carrier to run the network correctly.
Hope this clarifies my statement.
I never had to register or the like with my OPO for t-mobile. Didn't have to with my wife's OPO either.
It's a common enough issue across carriers. Sometime you do have to register the phone, and make sure you have the correct APN settings.
I just gave my daughter my OPO, I had Consumer Cellular (ATT) SIM in it. She dropped in her T-Mobile SIM and off she went, working perfectly. She's been using the phone about 2 weeks now, and in response to your question, I just checked her aPN, since I knew it's been working perfectly for her, only to discover the phone pulled in a MetroPCS APN! It's been working so well, she doesn't want me to change it to the T-Mobile APNs that are in the list.
Here is her APN settings (Calif-San Diego area), MetroPCS
name MetroPCS LTE
apn fast.metropcs.com
MMSC http://metorpcs.mmsmvno.com/mms/wapenc
mcc 310
mnc 260
apn type default,mms,supl
apn protocol IPV4
apn roaming protocol IPV4
mvno type none

What APN is you OPO set to?
I had just popped in the SIM card and it did work in my local area. But when I went outta town, my phone wouldn't connect to any services, no roaming either. I use MetroPCS on T-Mobile network, and nothing would run without activation on their system and registering the IMEI. So, results may vary depending on the carrier or area.

registering
I am a frequent visitor to the USA from Canada. Usually with my original Samsung or Nexus rdware from Canadian carriers, but unlocked.
Each US carrier has insisted on registering my IMEI prior to activating a SIM. It seems to the user you can pull a SIM and place in any old device and most times, no problem. But that's not the carrier approved method.
T-MO was very insistent on this. To the point they would not activate a SIM for me with out the device and the IMEI first
Hopefully registering with your carrier solves this. It's a thing and may be the point of issue for you.

I suggest you to go for the Korean model if it's not working. Just make sure to check lte bands for compatibility.

Have a chance to get a good deal on a unlocked sprint version.
Then go for it. But be sure to be Sim unlocked and lte bands accepted. The Korean sells for 800$ on eBay. Also can be flashed with European firmware and supports secondary screen. Imo has better quality also software aside. Noticed with LG G7... If you got better deal then go for it.
Are you sure it's unlocked and if so, how was it unlocked? I have a Sprint model and I'm having to wait ‘til my 50 service days are up to get Sprint to unlock it. I've contacted some pretty good unlocking services and hearing the same thing from all; As of now only Sprint can unlock it.
As we all know Sprint 5G service area (like all others) is very small but they're still charging everyone who activates this phone on their service for a 5G service plan regardless of whether they have 5G service in your area or not. I got a great deal on a 3rd party phone but it was locked which I knew going in. As soon as it's unlocked, I'm going to try GFI. BTW, it's a great phone.

Sadly lg value goes down extremely fast. I personally wouldnt spend anywhere close to retail with lg phones.

Wont be sure until I put my sim card in but it owner says sim unlocked. No interest in 5g anytime soon. If possible will disable/limit to lte.
One thing's for sure.... LG phones drop like a rock! I couldn't wait but I’m thinking in two months this phone's (sprint model) probably going to be selling for $400. Imo the only thing holding the price up for now is there just aren't very many out in the wild. Kind of strange really, since according to the Ifixit breakdown, it has the same Qualcomm 5G X50 modem as both the Galaxy S10 5G phone and the new Note 5G. Otherwise the specs are very similar. I guess it’s all perceived value.
Just in from Sprint tech support;
Hello,
Letting you know your LG V450PM BLK XCVR SGL on line 954-xxx-xxxx

My 50 days on Sprint are up in about a week. I'm moving back to Google Fi as soon as I unlock. Of course, Fi uses both Tmob & Sprint networks so I'm fairly sure is will work on one or the other.

Yeah, LG phones drop like a rock.
Some vendor on eBay was selling the Korean V50 with dual screen for $529......yeah.

I am just waiting for these to drop even more if that. Doubt the 5G works in other markets.
were you able to use wifi calling ? were you able to eliminate the 'activate' message. Thanks
Finally Sim unlocked and ported over to Simple Mobile, a Tmob Mvno. It was relatively painless and took less than an hour for the actual port. No reason to be on Sprint right now if you don't have 5G service in your area. I was on the phone with Sprint yesterday for at least an hour and a half and gave them every chance to do something about my bill. I asked them point blank why anyone would pay for 5G service when it's not even in their area? Their response was just lame. I'm guessing it will be at least one if not two years before 5G is working in a wide spread fashion in a lot of cities in the US.
Now, as for the service on Tmob's network, it's only been about a hour since I switched but have made couple of phone calls and run a couple of speed tests. Phone call quality seems same same and speed test speeds seemed the same as if I were on Tmob., 15 down and about 7-10 on the upload. Now the freaking really good news. Simple mobile is running a special for 3GBs data and unlimited talk, unlimited text. at $25 per month. If you do auto pay after taxes it's $22 and change.
are all t mobile bands available? Does it work with t mobile 5G?
As of right now, there seems to be a problem with the APN record on the sprint model. Sprint, the scumbag company that it is, has locked the APN. They'll unlock the phone to except other sim cards, no problem. But when your new provider tries to register your phone on their network it doesn't fully complete the process. In other words, part of the process is that a new APN record is pushed down to the phone identifying the new MMS DNS server for that network. I use Simple Mobile which is a MVNO of Tmob but Sprint has locked the APN on my V50. I;m still able to get data but can't send/receive pictures via text messages.
So be ware.

does wifi calling work? how are updates handled . thank you
We have a pair of sprint unlocked V50 and just got an update over the metropcs service.
In the service menu it says voice over wifi is provisioned but in the settings network voice over wifi is off and the switch wont stay to on position when i toggle to on.
I still see my cellular connection in the notification area disappear then reappear.
Is this normal behavior or is it trying to activate in background? Maybe it checking for 5G?
I think it using more batt then usual possibly
Now....... finally, some good news and this took a bit of doing. To start off with I originally tried an old Fi sim card I had to port out of Sprint after those scumbags unlocked my V50. I kept getting a T077 error during the Google Fi activation process and Fi support just kept telling me that the V50 wasn't a supported device and they couldn’t help. I told them I thought it was a bad sim card so they suggest I pick up a new one at Best Buy. So, after a trip down to Best Buy I found out that they rarely have Fi cards in stock so I picked up a Simple Mobile (tmob mvno) sim for a buck and the port/activation sort of worked in that I successfully ported my number from Sprint and I was able to make calls and get data but couldn't receive/send pictures (MMS) in text. So, I said screw it and order another Fi Sim card thru the Google site and waited a week. I got it yesterday late and tried it this morning and crap it didn't work with the same activation error, T077. I have been scouring the internet for days for any info the error code and somewhere along the way I remember seeing something about taking the mvno card out and then putting the Fi card in and trying to activate without rebooting the phone. Now remember this is really all about not being able to edit the APN record with the correct DNS info so you can receive MMS picture by text. Anyway, after slipping in the FI sim card to my V50 the activation process suddenly squeaked on thru and low and behold I'm now running on Google Fi with MMS working and APN record is correctly updated the Fi info. I think the reason it worked was that the activation process thought I was a Tmob customer. When it asked me for account info to port my existing number to GFI the dialog screen show things like.... Enter your T-Mobile account number and asked what was the name on my T-Mobile account. But for whatever reason it worked and now I'm finally free of Sprint.
It worked for me but your mileage may very.

What sms app do you use? Lg or Google? Cuz with Google messaging I have fully enabled RCS. Sending pics and videos over data and wifi. Why bother with mms when RCS technology is way better?
