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.

Global version works just great with AT&T, no need to get tmo phone that just makes it more of a pain int the ass to go through the unlock process

Unlocked Pre-Order from Samsung w ATT SIM - will I be able to use WiFi calling /VoLTE

Current Note8 user on ATT (phone locked to carrier). I pre-ordered a Note20 Ultra from Samsung direct, unlocked version. Have been off XDA really for a couple years and not rooting/modding much lately but have read that ATT will not allow unlocked phones on their network to use WiFi Calling and/or VoLTE. If true, are there workaround options for me (assuming I stick w ATT as the carrier I mean) to get these to work, or should I cancel the unlocked model and order the ATT version? Was hoping to root eventually and remove bloatware / play w custom ROMs again on the Ultra etc etc. - that is why I ordered an unlocked version.
Thanks gents for the guidance here! Best forum around for us phone geeks

If it will be like Note 9 or 10 plus just have to flash the U version csc with odin and it will give you wifi calling advanced..messaging..volte

Much thanks - I will do this then when it arrives.

Did not work for me on the unlocked note 10+. Worked right away on the tmobile.
Att was actually fun to have. Nothing that att expected worked on the unlocked device. For example I had unlimited hotspot, despite it was not included in my att plan.

That's bizarre. I am rethinking this unlocked route. I must have wifi calling since signal at the house is terrible in my area. I don't need the drama of uncertainty if this will work or not. Might as well cancel the unlocked one and just upgrade via att. Oy. Wtf is with att these days? They lost my directv account last year and now their wireless policies are looking like a royal pita.

I don't think you have to worry .... ATT seems to consistently allow Samsung unlocked devices to have carrier functions
You just have to flash the U CSC as mentioned above. Worked for me on Note 10 and is currently working on a s20 ultra device

Whats going on buddy. You jumping on the Ultra?

I strongly recommend switching your order to the ATT model. I got my note 10+ unlocked based off the suggestions found here saying that flashing the att firmware would give me all the features, and I've been through a year of headaches.
For a little wile i was able to enjoy wifi calling, voicemail and VOLTE, but after my first software update the features were lost. i was able to get them back briefly by putting my sim back in an old Att phone and keeping it for a day or two, but that trick never lasted past a week. I've tried re-flashing the software, switching back to unlocked and then back to ATT, basically anything i could think of and it never worked.
calling ATT didn't help either, as the reps gave me a canned line about not supporting outside phones. the whole reason I'm updating to the 20 ultra is to just get my phone fully functional with an ATT model

Thanks darth. Yeah, I switched to the att version. Hate the hidden tracking bloatware etc that comes with it but must have a very workable phone for daily work calls and wifi calling is a must. No drama is my motto these days. Thank you for reporting your experience.

I had the same situation with my unlocked Pixel 4 XL, keep calling ATT until I got the right person to modify my sim to allow WiFi Calling to work, that's my plan when I get my unlocked 20 Ultra.

I'm not a gent, but I doI have the Note 20 Ultra in for review and am using it with an AT&T SIM. VoLTE works, no option for WiFi calling.

What worries me is the 5G. Will unlocked work for ATT 5G?

It does on my unlocked Galaxy S20+ 5G. The Note 20 Ultra is a ways to release and their system doesn't yet correctly identify the IMEI, so I can't say for sure what will happen after release day.

Hi Lisa,
Your reviews are the best, so thank you first of all. Can you check if it has any eSIM capabilities? Supposedly S20 was going to get an update to allow eSIM use in US but that never happened...

Thanks . I'm not seeing anything under connection settings on our US unlocked Note 20 Ultra (there's no IMEI listed or cellular network option listed under connection settings when no nano SIM is installed. EsimClient is running on the phone, which makes me think the hardware must be there. EsimClient is not running on my GS 20+ unlocked.

Great, thank you for checking and comparing with S20+ !
eSIMClient running gives me hope that we will get eSIM support in an update...Still perplexed how or why Samsung has gone out of the way to disable eSIM on US variants when Apple, Google support it.

Ha! Thanks Lisa (love your tech vids!!) - I switched to the ATT version. Supposed to be here 8/21. I can't take a chance with wifi calling being borked, or that just that I may need to Odin-flash updates or CSC packs periodically to keep up with the monthly patches (ie force an unlocked unit to keep working on ATT's network if my previous firmware gets overwritten etc. I mean). I guess as I got older I went from a tech pioneer and adopter to just an end user LOL.... I just need it to work. Maybe I can do that package remove thingy and chop the bloatware periodically... we shall see once the community gets these units and starts their dev magic for us.
I guess I will need to make an appt at the local ATT store in a week to get on a new 5G plan from my current 4G one to take advantage of the coming speeds.

You're welcome- glad you enjoy our vids! With AT&T, you can simply change your plan online, no need to visit a store. The mid and high tier unlimited plans include 5G.

Could you tell me more. I have the US unlocked note 20 ultra, I put an AT&T sim in (from my note 9 unlocked) and I can't find an option to turn on wifi calling. I pretty much gave up on feature like this, because I would rather have the unlocked phone, but if it works now maybe I am missing something.

Help going back to TMobile from Global

So I am having remorse about going from stock Tmobile firmware to Global. The 5G connection just does not work well. I cant get standalone 5G and do not want to root to get this.
This is unfortunate because i like the way the global works with dual sim and less bloat but the lack of good 5G is not acceptable. I have tried to enable standalone 5G and it just does not work. I even flashed a tmobile modem and the phone would not boot so i had to flash the global modem back.
What is the easiest way to back to stock rom and if possible not wipe all my data?
Obviously i am unlocked but not rooted.
I am on Global 11.0.6.8.KB05AA and want to eventually get back to the current stock Tmobile as i received from the tmobile store when i bought the device. is MSM tool the only way? or can i revert back using a local upgrade assuming that the tmobile update is newer than what I have now? And where would I get a full rom of tmobile?

I am also on KB2007.
when I screwed up root and completely janked my boot partition the only remedy was MSM tool.
I could not find any images for the 2007 variant.
That was a month or so ago so maybe someone has pushed them out since, but im not aware of an offical repository of 2007 images.
I would love to see one if it existed though.
I did find the MSM tool while unnerving as I thought I had bricked my phone at the time surprisingly simple and effective to use.

I believe msm is the only way but I'm kind of in the same boat as you. As much as I like the global for the fact it has less bloat, i feel like the data connection in general was affected.

MSM is the way to go. I did it yesterday.
On global I could not connect to the 5G signal. The funny thing is at my location the 5G speed test is 1/2 speed of the LTE! Oh well!!!

It's been stated on various forums for various phones that 5G is not always faster than LTE. It all depends on where you are located, what phone you have, and what carrier you are on. 5G is still overrated for the next few years.

Hi
Have Samsung galaxy 2 fold at&t unlock
Can I change Carrier from att to t-mobile I flashing T-Mobile firmware or can I just Flash csc??

if your phone is sim-unlocked, once you insert a t-mobile simcard it will change the phone to t-mobile. no need to flash anything.

Yes, it works for making phone calls, texts, even 5g. But you won't get OTA updates. At least that's what I was told. I'm typing from a purchased AT&T unlocked Fold 2, with a TMobile sim inside. It works fine, just no updates. Still on One UI 2.5, and android 10. I'm actually here hoping to change this by flashing a TMobile rom. I did a little research last night, and it seems a little scary with the danger of bricking the phone. Back in the PPC hayday of flashing roms, I was all over it. I even flashed a few roms on my s6 years ago, so I have some experience with Odin, but it still seems nerve wracking because I can't return this phone if I brick it. Bought it used.

@vinscuzzy I feel you because I understand what you're going through. I used to flash my devices back in the day. I haven't flashed or rooted in a long time but like you, I also have an unlocked AT&T branded Z Fold2. It seems easy enough. Any reason why you would install the T-Mobile firmware rather than the U1 Unlocked version?

Theoretically I would think the unlocked version would be better because when theres an update, I'm guessing, we wouldn't have to wait for the carriers to do their stuff to it. But I'm not 100% sure if that's how it works anymore. The last truly unlocked phone I had was a Nokia 1520.3, with windows mobile, and it was great, BUT if I remember correctly I had trouble with wifi calling, visual voicemail, and tethering. I actually asked @zimgir124 the same thing in the other thread about which one is more beneficial, but haven't heard back yet.

Well, I just found another thread on how we can go back to AT&T in case we need to.

If it's running well now I would not be concerned with updates. You could well end up with a less functional device by updating.

T-Mobile Note 10 Plus 5G

I unlocked my note 10+ 5g from t-mobile, but it won't get service with verizon.
When I install a non-tmobile sim, the software does not switch from tmobile for some reason.
Also Sam Mobile only has t-mobile and metro pcs firmware availible for the sm-n976u
Does anyone know if there is a way to get the phone working with verizon? Thanks.
-God Bless

Try clearing Sim card tool kit data.
Network reset.
Clear system cache.
Edit Access point names to correct values.
That's all I got but sure there's more. Never had use more than the above but never changed carriers. Verizon advanced tech support should be able to help... AT&T would.

The Verizon Note 10+ 5G has a different model number. So they probably won't allow the T-Mobile/Metro/AT&T version on their network

I think you're correct. AT&T is compatible with Tmobile but not Verizon according to B&H Photo compatibility charts.
So it look like AT&T is in your future. AT&T is easier to deal with anyway. Do not use a corporate store though, use over the phone or online AT&T.
It may be possible to change out the C port PCB for the Verizon variant. Yes that PCB controls internet access. I can't confirm this is the only difference though! That PCB is only $20 and relatively easy to change out.

It's gets service with att, but it still has the tmobile boot logo. I flashed the att rom, but it didn't help. The carrier is supposed to automatically switch when you insert a different sim card right?

It's actually super difficult to hard brick a Qualcomm device, and even if it is hard bricked and only enters EDL mode, it can be fixed as long as you have the correct files.
There are too many safeguards in place between Qualcomm and Samsung - the average user will always be blocked from doing anything that would brick a device. There's really no danger in flashing firmware whatsoever

I hope I can be of some help.
I recently ordered a Note 10+ 5G - Locked Verizon from a popular online re-seller. When I turned it on, I was greeted with an AT&T boot logo. I was pretty upset, but I though I'd try to get it up and running on Verizon before spending a couple weeks sending it back and getting a replacement. I tried Verizon's online software and I couldn't get beyond the IMEI change. It kept telling me that the Note's IMEI was what I was already using with my Droid, which was obviously not the case. So, I headed into my local Verizon store.
Nothing they did would get my 4G SIM to work, so they swapped out for a 5G SIM for free, then switched my hardware IMEI numbers and proceeded to have a some difficulty getting on the network. After doing a network reset, it seemingly worked. More on that below. I was getting both data and voice over network. I was able to transfer my setting, apps, etc from my Motorola Droid with Samsung Switch. The phone indicates both 3G and 4G signals as I travel around town. 5G is not available in my immediate area, though it is in some cities I occasionally travel to, but I'm unable to test that just yet. I become aware that there are differences between Verizon's 5G and other networks and it seems the non-Verizon phone I have is probably for the best in terms of compatibility.
Unfortunately, texts frequently take 10-30 seconds to send. Images, gifs and other non-text MMS can take multiple minutes to send and sometimes just fail. Other times the recipient will receive them twice. I feel like this may be due to the poor coverage at my residence. Further testing in areas of good to excellent coverage are necessary. I tried changing the network settings from Settings > Connections > Mobile Networks > Network Mode, but anything other than the default "GLOBAL" would result in a disconnect of data and voice services. The only way to fix it was Settings > General Management > Reset > Reset Network Settings. This would restore the Mode to GLOBAL and bring back data and voice services.
In an effort to remove the AT&T branding, I learned how to trigger a carrier switch, dialed the code and changed it from AT&T to XAA. That got rid of the AT&T boot animation and I was able to remove all but 2 stubborn AT&T apps. I noticed that my android version was 10 and UI was 2.5, so I set out to update.
This is where things got frustrating. Every attempt to update through the settings > software update was met with failure. Try again in 24 hours, it would say. I assumed this was because I was now using a Verizon sim on an AT&T firmware, but I wasn't sure. I thought I might be able to flash to a Verizon firmware, but after several versions and some more research, I learned that going from 976U to 976V was not possible.
So, over the course of several days, I learned a lot. I looked up the firmware releases on AT&T's website for the 976U and saw that they matched the T-Mobile and MetroPCS versions. So, I settled on a T-Mobile version of Android 11 / UI 3.1. It updated without any issues and even remained in XAA mode. No bloatware, no loading images, all settings and apps the same.
So, even though I have an unlocked AT&T Note 10+ 5G 256GB and you have a T-Mobile, the fact that we both have a 976U model, I think there is hope for you to get up and running on Verizon.
Hope this has helped.
