I have been battling with this no LTE case for this Galaxy S7, BYOD. This is the official US unlocked version, and works with Sprint (on their whitelist), furthermore, my wife has the same phone rocking LTE with FP right now (BYOD as well, so on sprint network), so it's compatible with FP's service.
My understanding for FP byod (based on previous exp) is that if the phone was activated on Sprint network before, the MEID and the ICCID info is stored together, so even if BYOD process only ask for MEID, as long as you have the previous activated SIM, the ICCID info get carried together, so you normally would have no problem getting LTE.
This Phone was never activated on Sprint before, so when I first activated it BYOD, so no previous SIM info, but I plugged in a compatible SIM that was activated on Sprint network before (with another MEID though). My initial activation had problem (red bar on my account summary), had to email customer service to add this ICCID. Phone passed the hands free activation and all. No problem using the fp apps, phone, sms, cellular network worked (only 3G).
I then started to do all kinds of reset trying to get LTE connection. I have done,
1.##72786# carrier reset
2. Restore APN setting to default, clear cache, reboot
3. Matching all the LTE related parameter with a known LTE connected phone (my wife's GS7)
4. factory reset
5.Deactivate and then reactivate the GS7 (by swapping devices between two fp accounts)
Now almost three months now, I'm still facing the same issue. FP customer service has been helpful doing the routine checks, but not beyond the suggestion of PRL update/reactivation. The final solution they offered was to deactivate the account and the activate the GS7 with another byod account. I did this just today, by swapping another device in this account, and then reactivate the GS7 to that account.
My very first concern is if the ICCID info has been accurate (not missing or mistaken a digit), but I asked them to verify this at least three times, nothing came back as error.
Compared to my wife's same GS7 with fp, my phone is rather slow to establish the 3G mobile data connection, for example, her phone would almost show LTE instaneously after a reboot, but my phone would be at least after a min to show the 3g icon.
Can someone share some insights on what else I could do? I just could not think of anything else from my phone side to do. A note worthy thing is, when I helped BYOD my wife's GS7, I was in the same boat of needing to add ICCID via customer service to pass HFA, and then all the reset to get the LTE. I actually wasn't able to get LTE connection by what I did, shut off the phone with 3G connection, but next morning I turned on the phone, LTE was there. Along with me, I saw multiple users who had similar no-LTE problem report they were getting LTE same day.

Hi mate
Maqybe here they can help you better , this section is for the exynos model
Thread closed.
Please continue the discussion here: https://forum.xda-developers.com/sprint-galaxy-s7/help/g930u-freedompop-lte-connection-t3619028
A couple of weeks back, I purchased a factory unlocked S8+ Model #G955U1, Baseband Version G955U1EU1AQE3 (The AT&T Galaxy S8+ has different Model and Build #s), inserted my AT&T SIM card and have been using it since. Then I decided to activate WiFi calling, however, unlike my wife's iPhone 7, my Galaxy does not have the option to enable WiFi calling (this option should be under Settings>Connections). After some research, I found out that this a carrier feature which AT&T must provision. When I asked them to do it, they provisioned it on my wife's iPhone 7 but not on my Galaxy, so I called them again and asked them to provision it on the Galaxy. Although they insist that they did, the feature does not show up on under AT&T Devices (It shows up under the iPhone but not the Galaxy). After spending no less than two hours speaking to three agents, I learned that AT&T does not have in their data base the IMEI number of the Galaxy because it was not purchased through them. So obviously, not having an IMEI number, the WiFi calling feature is not going to be pushed to my Galaxy. Not being able to solve the problem, they escalated it to another level who is supposed to contact me two days from now. A friend purchased his Galaxy S8+ through AT&T and the WiFi calling option is there in Settings>Connection and he is able to toggle it on or off. When I used AT&T's IMEI Verification tool, the result was "Device is compatible but we cannot find matching SIM card".
Any and all input would be appreciated.
Same here. Looks like wifi calling is not a feature that is available on the unlocked version unfortunately. Same with using LTE while on calls and built in visual voicemail :/
You have some advantages going unlocked but you lose some things too.

But you can always use Odin to flash the ATT firmware to the unlocked device. There's plenty of threads here regarding this very subject.

True, just keep in mind that future att updates can't be done via OTA - which can be a pain too.

With the unlocked s8+ i've found that wifi calling and volte only worked on T-Mobile, I tried it with T-Mo and verizon. It stinks that ATT cant be more like T-Mo with accepting non branded devices

I am pleasantly surprised and a bit puzzled because when I spoke to T-Mobile Tech yesterday, she could not confirm if WiFi calling will work on unlocked S8+. If I can be assured that it will work, I will switch to T-Mobile.
Please do me a great favor and check if your unlocked S8+ has the same Model and Build Numbers as mine. Here are my numbers:
Model #G955U1
SM-G955UZKAXAA
Baseband Version G955U1EU1AQE3
Thank you.

All the information you provided matched with my phone. As a matter of fact, I also tried my friends SIM who is on MVNO called Mint Mobile that runs on T-mobile network. Mint also allowed me to make wi-fi calling. I am surprised that t-mobile rep could not confirm this feature because this feature is on by default! If I don't want to make wifi calls, I have to turn it off. The only little annoying part is that you get constant notification," Calls will be made over WiFi". Even when you block this notification, it will reappear on the reboot

Thank you indeed for your response. When I got my S8+ and before inserting AT&T SIM, this feature was NOT listed under Settings>Connections. I was informed by a Samsung agent that the carriers will push this feature to the phone through their SIM after they provision the feature. So now since my SIM is AT&T and my phone is unlocked, and its IMEI number is not in AT&T's data base, I don't have the feature listed.
Unfortunately, I can't comment on at&t network. On t-mobile, I did not have to do anything except during the initial setup, I was asked if I was ok to make wifi phone calls when a wifi connection was available & the signal was strong. I still have the option not to use this feature. You may wantvto visit a t-mobile store or find a friend who is on t-mobile network. It might not be a bad idea to reset the phone (after backing up) when you get the new sim card. Good luck ?

I switched yesterday from AT&T to T-Mobile and immediately the wifi calling showed up in Phone Settings as you mentioned. However before switching from AT&T to T-Mobile, wifi calling was not anywhere to be found.

That's because WiFi calling and VoLTE are not available on ATT using the US Unlocked device. You have to either buy an ATT carrier version, or flash the ATT firmware to your current device.
Try to reset to factory defaults with sim inside
I'm on Argentina and with unlocked software i got wifi calling when the device is set up with my sim inside

I found that after wasting several hours with AT&T's techs. The 3rd option is to dump AT&T and switch to a carrier that has wifi calling available for unlocked S8/S8+ phones such as T-Mobile.
Wi-Fi Calling works great for me

To access Wi-Fi calling you need to open your phone app and hit the settings button in the top right corner and then scroll all the way to the bottom and it will be there.

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.

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;

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?
Pardon my noobness, I will explain this to the best of my abilities
AT&T told me that my current phone Samsung S8+ will not work on their network (international dual sim unlocked version). They said that it is because "the 3G will shut off" but this phone is clearly a 4G phone. To be more specific, my device is a SM-G955FD. They sent me a replacement phone which is less than crappy and said my current sim will be deactivated soon.
I have already rooted (and ROM'ed) my phone - and I know you can change device identity/fingerprint using build props. I want to mask my phone as a SM-G955FU which is the USA unlocked version. At this point, I'd like to know if this could make a difference and make my phone not be deactivated by fooling their system, or if there are other things to try.

Help appreciated,
I don't think they query device's brand / model property as stored in Android's build.prop file because these characteristics at any time can get changed by user.
The speed of data access relies on two things: your phone and your service provider. Every phone has a radio module that is responsible for talking to the network. It is this piece of hardware that either can or can not use latest communication technologies: if the phone does not support 4G, you will not get that speed whatever you try.

It is this piece of hardware that either can or can not use latest communication technologies: if the phone does not support 4G, you will not get that speed whatever you try.

Thanks, what is odd is that it should support it on several bands
Will Samsung Galaxy S8+ work in USA?
In this page we are going to show you the compatibility of Samsung Galaxy S8+ with the mobile networks of USA and with the telephony operators that provide service in USA.

The same thing happened to me today, woke up to a sim not registered message and no cell service (voice, sms or data).
I went to the store and they said my unlocked Moto G7 Power (XT1955-2) is not supported/compatible on ATT's network. I re-checked the phone's specs and it supports 4G LTE on bands 12 and 17 on 1900 Mhz which overlaps the data I found for ATT's network. I'm not well versed in this stuff tho. Perhaps it's a local towers thing and I am in an area where their towers are operating on the other ATT frequencies (1700, 700)? The guy at the store did something (I forget the exact details) and I do have voice back, but that is it, no data or SMS. He also mentioned that ATT is like cracking down on what kind of devices can connect. If ATT is blocking my device tho I'm curious, how is it possible? I guess they can lookup my device via the IMEI and then see if it's on their approve list of devices?
I don't understand their problem. Your phone model is listed as supported as long as you update your software to enable WiFi calling (VoLTE). Come 2/2022, you phone must either be 5G or VoLTE calling enabled to be supported. My Xiaomi Mi Mix 2s shows that it can do VoLTE under the sim card details in Settings and supports 13 LTE bands, including AT&T's bands. It should continue to work on their network after 2/2022.
Yet AT&T repeatedly disabled my phone. I had to tell them to re-activate my phone multiple times. I have tried some new phones. Turned out everytime I pulled the sim out to try a new phone and stick it back in my old phone, AT&T would check the phone's IMEI again and would disable the phone. On the 5th call with them, they put in a code/note in their system to mark my IMEI (be ware each sim tray has its own IMEI) not to be disabled until Fed 2022. I have since tried Surface Duo which on this list and decided not to keep it. Stuck the sim card back in my old phone specific sim tray and it continues to work.
Call them to re-activate/keep your phone active until Fed 2022. They have no rights to disable your phone before then.
Most A&T reps understand less than us on the reason to disable our phone. They jsut keep saying 3G phones will be disabled but our phoens are clearly LTE. VoLTE is one real reason of the problem but them our phones support VoLTE anyway. I am tired of arguing with them and am looking at a Note 10 now. But your situation got me concerned. Sounds like they may not honor the supported list which is updated frequently. I downloaded the June version of the list which is largely the same as yours and asked them how long they would support the phones on the list. They couldn't/wouldn't commit. Even on the phones they sell at their website, they would only give a vague promise to support them for "quite a while".
AT&T has always advertized BYOP. We spent big money on nice phones that are compatible with their network. And now the want to shut us out.
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.
