Unlocked model AT&T sim tethering issue - Samsung Galaxy S20 FE Questions & Answers

Just turned this on, then inserted AT&T sim and it asked to reboot. Once done I was able to put in APN then turned on hotspot and set it all up. I got data on the phone, laptop can connect to hotspot but no internet. Playing with all the settings and still no internet on tethered devices. Did unlock version somehow download AT&T firmware and block tethering? Help?!

My unlocked phones have been doing this on at&t for a couple of months now. I think at&t just wised up to it somehow, but I'm unsure.

I am using hot spot right now..I do all day...using the FE on AT&T. No problems at all...but...I believe it depends on what plan you have!
I am on the unlimited elite so maybe that's the reason. Not sure why you would have to put in an APN??? THat should be automatically enabled when the SIM is installed.

no firsthand knowledge, but it sounds weird. you sure you have the right APN settings for data? the right type of plan on t-mobile? if it's unlocked and you have a t-mobile sim in it, it should work. i bought a used at&t model and am using it on straight talk.. granted it's the at&t side, but still i had to add an APN etc and it did that without a hitch.
also one thing i've never experienced before is the at&t wifi hotspot thing. it's connected to wifi networks out in public on its own but lately it's saying i need to confirm eligibility. that setting is in wifi to turn it off. perhaps you're connecting to wifi or something? no idea though.. just trying to brainstorm for you!

[Q] Pure Edition AT&T Go phone

I recently purchased a Moto X Pure Edition and am trying to use my old gophone sim (previously in a feature flip-phone) in it. I have tested and confirmed that it works correctly on T-mobile, however when I put my gophone sim in it, it shows service for 30-60 seconds and then goes to "No Service" which I know is not true. It is also worth noting that I can't turn on cellular data. As soon as I do it turns itself off.
Other things that might be relevant:
My gophone plan is the 10c/min, no data plan.
This was originally a full size sim which I cut down to nano size. I have put it back in my old feature phone with an adapter and confirmed that it still works.
I have tried a dozen different APN settings, including copying the APN settings from a friend's Moto G that has the same plan, with the same result.
For the short period that I do have service, it usually works correctly. I still can't turn on mobile data, but I can make and receive calls as well as send and receive non-MMS text messages (MSS requires mobile data). Sometimes attempting to text/call seems to trigger me losing service, but that might be a coincidence.
I'm currently on rooted stock 5.0 lollipop with an unlocked bootloader.
Any ideas how can fix this?
I am going to try using my friends gophone sim and see if that works. I will update with the results of that.
Att contracts require data plan for smartphones. Maybe related. Call them and ask.
As I mentioned, my friend has a Moto G with the same plan. I did call and they suggested I get a new SIM. I'm going to do that, but I'm doubtful of the result

Problems with using this phone on tmobile

Just switched from verizon to tmobile. Thought I can just pop the sim in, adjust APN and be good to go but it didn't turn out that way. Two major issues: only getting 3g connection and unable to activate hotspot. Phone is not rooted but can root it easily. Are there stable fixes or should I just sale and get a tmobile phone? Thanks

There is a particular G4 model (H811) which has the highest compatibility with T-Mo US. So do you have that one, or something else? (eg the Verizon-specific model: VS986)
The H811 is 100% compatible with Tmo, the Verizon model is probably barely compatible. (Verizon's network was historically based on CDMA, and regular voice/SMS still travels on that network, unless you have VoLTE working on your device)
Also, you do not get hotspot capability on any T-Mobile plan. Currently I have 2 T-mo phones, my daily driver at the moment is still on Verizon. So I have a low-end SIM for T-Mobile (infamous online or Walmart $30/mo plan) which includes 5GB of monthly data but you cannot do tethering/hotspot with it.

Restore wi-fi calling - carrier unlocked

Hi. I'm new (and old) so apologies in advance for any faux pas. I couldn't find another thread with a problem like this, so I'm posting a new question.
Here's what happened:
I have been using Ting MVNO SIMs on two Galaxy S8 phones for about 18 months. Preparing for an overseas trip, I asked T-Mo to unlock the phones so I could use foreign SIMs.
T-Mo unlocked the phones, but now I can't get wi-fi calling to work on the Ting SIM. Tried a MintMobile and FreedomPop and the same thing, no option in the tools or phone app to activate wi-fi calling although it is activated at the MVNO and the E911 addresses are correct.
T-Mo says it's impossible that unlocking did that. Well, it happened. Ting doesn't have a clue about how/why it happened or how to fix. Samsung says it's the carrier's problem not theirs.
I factory re-set hoping it would restore the lock, but that didn't do anything. I don't get a signal at my home, so wi-fi calling is necessary. My next step is to buy new phones.
Ideas? Thanks!

Samsung note 9 N9600 VZW network issue

Hi guys,
My toy is a samsung note N 9600 and its factory unlocked. Last week ported out from T-mobile to keep my original number and facing a wried issue.
The day I ported out from T-mobile, VZW network couldnt be recognized when I tried to activate the VZW sim card. "No network connection." and no call or text can be made. However, after I RESET my device to factory model, it SUCCESSFULLY recognized VZW and LTE function works well. Sounds wried? The story doesnt end here.
Yesterday after I turned off the VZW sim card by accident-- n9600 is a dual sim card which allows you to turn either sim card off-- the network connection lost again, im not talking about LTE connection, but all network service including internet, phone call and text function. Tried a lot to get the connection back but failed. Guess what? RESET, THEN VZW comes back!!! Being driven by curiosity, I turned off the sim card agian, and then, as my expect, no network connection. Ok, rest---works---turning off sim card---no connection---reset……
I am really annoyed by this and have no idea why it is. So if anyone of you have clue of it, plz let me know. Thank you in advance!
Teddy
