Galaxy S10+ G975U - LTE drops - General Questions and Answers

I recently purchased an open box Galaxy S10+ G975U. Phone was in excellent condition. Was told it was an unlocked phone from Verizon. Upon receiving it, it had ATT Splash Screen and Apps. Was trying to get it working on Page Plus, and MVNO of Verizon. After much effort between seller and Page Plus, we finally got just about everything right.
We switched it back to Verizon Splash and Apps. We got everything working or so we thought finally with some APN changes. However, after using it a day or two, I noticed that during a phone call, LTE would always drop to 1X, thus making MMS and Data usage unavailable. Page Plus Customer Service is not good, some are better than others, but I cannot seem to get the issue resolved.
I recently got rid of the Verizon from CSC just to see if it would help and switched to XAA/XAA/VZW. Thinking it would help and it has not. My Galaxy S8 that still works with the same Sim Card with LTE that works correctly as well during calls, has a CSC with TFN/TFN/XAA.
I do not have the ability to switch to Tracfone (TFN/TFN/XAA) but don't really think that is the issue as Page Plus uses VZW devices.
Does anyone have suggestions or an answer as to what could be the issue? I have collectively spent at least three full days of my life between customer support and reading through all the forums and posts.
Thank you in advance to anyone who replies or has knowledge that may help.

Project Fi on galaxy s6?

Ok ok before you all start saying that Project Fi is only on Nexus phones hear me out:
If I have an Galaxy S6 and pop a Project Fi sim card in it. What would happen? Will it not work at all or something else will happen? Will it work for all services(talk, text, data) or just some of them and in a limited way?
And assuming that I can use Project Fi on S6 then I have these questions:
Will it effect the cost of my bill at the end of the day? If I use a non-Nexus phone how much more will I be charged and for what exactly?
Oh and the last question: Will it work on all editions of galaxy s6 or t-mobile compatible models only.
I already have an invite but do not want to buy a new phone just for that and my current plan is not that bad.
I just tried this. I put the Project Fi SIM in on Tuesday and waited for my number to be ported. Today I checked the Fi app and it said there was a problem with my SIM card and to contact customer support. Of course, they just hit me with the rhetoric about it not being compatible and that, despite videos showing it working on the S6, the forums say that it stops working after a few days or they start getting a lot of error messages. This doesn't really make sense as it's basically just cellular service, but whatever. It seems they don't want it working on anything other than their flagships, and I'm not buying something I can't afford when I have a better phone in my hand right now. I'll be checking MetroPCS or the like instead to get away from T-Mobile.
I ordered my sim card and did the same thing. Just like you I run into the similar situation.
For activation you can only do it on a nexus phone. They can actually see what kind of phone you have when you activate. Also number porting takes a few seconds to a minute to complete. If it gives the error right away then the problem is with the phone model.
Wonder once activated if it would work?
Galaxy Note 5 On Project FI
I switched Sims between my Note 5 and N 5X on fi, and the Note 5 is fully functional.
Has anyone tried to use Project Fi on an S6, Note or non Nexus device outside of the US?
I have it working on my S6 Edge, but I'm curious if it will work in Europe.
Remember which networks this rides on
I think if you were to use a phone unlocked for Sprint/T-Mobile this would work. Remember that fi rides on Sprint and T-Mobile networks.
I have fi in the UK. However I am using it on a 6p uk version and it works fine

Hi people,
Been reading the forums for help for a long time - finally decided to join; hopefully will be able to help... I am not a pro - actually quite a newbie; hopefully will become a pro spending enough time here
I am trying to make my SMG920V (Samsung S6 Verizon unlocked) work with Project Fi. It is working but only very poorly.
T-mobile network shows up but disappears intermittently (I changed the APN settings from apn . gishan . net)
Even when it works, I am getting only H or H+, not LTE
Request your help please?!
I would ideally not like to root the phone (my wife uses it and she knows nothing about technology!) but if that is the only option to use all bands (IF that is the problem) then I will; the phone is on 7.0
Looking forward to your help!

[HELP]Samsung Korean S8+ KT - SM-G955N TMobile Network Problem

Hello everyone, im new here kept searching everywhere for solution for my problem without any success. In may 10 i bought SM-G955N KT module, it was working great with 2g / 3g / 4g / LTE / LTE+, i went out of usa for almost 3 month and when i came back my phone doesn't work well with tmobile, i can send msgs use lte internet but i cant do calls at some areas, some times i have full lte bar and when i try to make a call it goes to 0 signal bar, i called tmobile many times about the issue but no solution i found out that they did upgrades to their towers in the period i was out of usa from may to august, right now i cant use the phone as any normal person its been a month that i cant use the phone at my house and some areas, i can make calls sometimes if im at different tower locations. Question is, is there any solution for this problem since tmobile did those tower upgrades its screwed up everything..... should move out to att or verizon or what should i do. I really need help with this problem its been a month, any solution would be welcome if it requires root or not i dont care i just want to find a solution for this,
Thank you.
Have you tried resetting your network settings and/or getting a new sim card?
Its not the sim card i already changed it to a new one also i tried it on a iphone 7s plus and it works fine, my phone is bone stock no root no custom software alsi its the korean version when i looked around i found that tmobile did some network upgrades from may to aug and thats when my phone got screwed up, i was albe to play with the ims setting and i got the phone to recive calls but i cant make calls, does my phone screwed up because it has the korean csc and the stock firmware or whats going on here
I'm not quite sure I understand your experience. From what I am reading, you went to Korea, got the G955N (which I bought for both myself and my wife), and then came back to the states and can't get it to work with T-Mobile?
I tried to get mine to work with T-Mobile and have experimented extensively with different CSCs and ROMs.
I eventually went over to AT&T
I've also had a rather extensive experience of how to get 4GLTE working here in the states with AT&T.
Feel free to reply here or DM me if you wish.

Hello thanks for your input, actually i bought the phone in the box brand new from amazon, it came here on may 10 i used it for 7 days 4G LTE 3G works great then i had to go out of country for 3 month i came back at the end of august to find that tmobile did a huge tower upgrades in my area, since i came back i wasnt able to do calls and receive calls, i was only able to text and use LTE internet but not calls, i went to different towers area and i actually was able to make calls but not in every area because some times my signal bar goes down to 0 or even 1 signal and i cant make calls still but my other friends who owns iphones or usa version of android works fine except me. Yesterday i edited the IMS setting im still on stock fw and i enabled every single feature there and i was able to receive calls in my area but still i cant do calls, i wanted to make sure if im gonna follow the steps here in this guide i will be able to use TMOBILE CSC with the korean stock firmware and get the features of tmobile as VOLTE and WIFI CALLING etc with the right CSC for sure and without tripping knox
Thank you
Hi, I did some extensive searching and was not able to find a solution for this.
I've got the SM-G955N, and ran into the same issues as other users in this thread with T-Mobile, has anyone found a workaround to unlock the LTE bands necessary to make the SM-G955N work with T-Mobile?
I didnt find solution yet too, i dont know what to do i gave up i tried everything on the official software no root.

I had a phone with the Korean CSC as well, N phone as well. I left the CSC alone and it worked with T-Mobile and ATT here in the US just fine, last fall.
I later changed the CSC to XXA, and still works well. Just tested it this week with T-Mobile, and it's working. I have to say, that locally, T-Mobile has much poorer spot area service than ATT. Kinda puzzling, but that is the way it is.
My phone is rooted, so it make things a bit more handy to mess about and return to my previous setups.

Data not working at all

So having recently upgraded from an unlocked T-Mobile device running on ATT, I was expecting that I would have better connectivity since the T-Mobile device I had didn't have support for a lot of bands. However I haven't had data work at all since setting up this phone.
Full disclosure, I'm on blackwireless. But it's an ATT mvno so I should still get their network.
But I'm getting zilch.
Talk and text are just fine, just no data.
I'm also not fully used to the interface on this phone cause my old one had actual "bars" in the icon and would also say LTE or 4g. Maybe both, is it sad that I've already forgotten just three days into owning a op7?
Firstly, anyone else an blackwireless, or ATT having issues with data?
Haven't yet called blackwireless because their support is 100% outsourced.
Had same with T-Mobile, it wanted me to sign in...and that page said this plan has no internet. So I called support, they ran a diagnosis but before it could finish ! Near the lte disappeared and it worked

Have you looked at your APN settings?
Sometimes it just doesn't select anything or it's empty!
You're right. That was the exact problem. I ended up calling the support line and it was a much better experience than I remember. And there were several apn to choose from. I just had to choose a different one according to their documentation.

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.
https://www.ebay.com/itm/LG-V50-Thi...972866&hash=item1f015f8485:g:k9wAAOSw4kZdX2mi
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?

Question An A52 4G Dilemma

So this past summer I purchased a 4G version of the A52 from Amazon, my main reason being it was cheaper than the 5G. Now I'm finding that this choice may be affecting my carrier situation. I am in the United States, and had Cricket Wireless at the time of purchasing the phone. It worked for about 4 hours, then the service quit on me. Apparently Cricket claimed that my phone did not have the proper technology, blah blah blah, something to do with the discontinuation of 3G and or VOLTE. This obviously does not make sense, since this phone is from 2021 and would not be made with old tech. Anyway, I got them to turn my sevice back on, after it being in a "suspended" state. It was still working for a while, and then some time in september I think Cricket sent a text to me (and my fiance as well, also has a phone cricket doesn't like) saying that they would start redirecting our calls to customer service to get us to "upgrade" since the phones would supposedly stop working completely in February or whenever 3G is supposed to go kaput. So, we switched to Mint, who claimed that our phones would both work on their network, and they did, except that the service sucks, even while being in a modest sized city. It also has little to no service at my work, and I'm convinced that T-mobile's service, at least through Mint, absolutely sucks.
So, my question is, what do you all suggest? Does anyone have this model, and what carrier are you with? What kind of luck (or lack thereof) has anyone been having?
Sorry if this has no place here, just doing all I can to get some answers
Well, I don't think I have a clear answer to your question, this is something that I found very very weird. I handed over a Galaxy S9+ to my fiancee who's carrier name I forget, I think it also got acquired by T-Mobile, but I'm not 100% certain. However, the phone didn't work properly. I can't remember what problems exactly it had but they were network related. Turns out that if you're going to change phones you need to go to a store for them to configure it and change it in their system. Otherwise it will either not work or not work properly.
And this was also the case with her sister who bought an unlocked, Mexican phone and she also had to take it to the store for them to configure it. It would have these problems unless she took it to them.
You would assume that all you need is to insert the SIM and it would work out the box but I don't know why this carrier had this method which just makes everything so annoying and complicated when it doesn't need to be. Oh and this isn't a one time thing, every time they changed phones they would need to do this! So you should probably look at going this route, it's my best guess.
EDIT: Oh and also before we knew this, we had also purchased a Galaxy Note 3 (which yeah it's old, but had 4G when I used it with my carrier and all of a sudden it turned to 3G when used on her carrier) so we ended up giving it away. So it was definitely a carrier problem. It was so annoying.
