I bought a Samsung Focus the other day from AT&T.
I have a 'go phone' SIM for when I'm in the US, I live in Canada and am with Telus.
I ordered an unlock code from nckzone, and it worked to allow my new focus to work with my Telus SIM.
But when i insert my AT&T SIM, it shows Emergency Only.
the phone (as far as I can tell) is unlocked.
When I go into the diagnostics and check the network lock, it says 'disabled'.
Any suggestions on how to get this working with the AT&T 'go phone' SIM?
As the title states, I decided to fork out 20$ on an unlock code for my SGH-T999L. The unlock went smoothly, but I can't connect to any networks for some reason, whether I use my inactive AT&T SIM or my active MetroPCS SIM.
When I set my phone to auto-select the network, it tells me that my SIM doesn't support the network it picks. When I search for networks, I get T-Mobile, AT&T and "311660" on both SIM cards, which neither of them will connect to. I'm sure it has nothing to do with APN settings, as those are solely for MMS and Data if I recall correctly.
Any ideas?
Were you using it with metro before the unlock?

I recently switched carriers and took my unlocked SGH-I747 to T-mobile. It's worked decently though not as well as it did on AT&T. I subsequently rooted the phone.
In looking through the settings, in the "Network Operators" list, it does not show T-Mobile. It only shows AT&T, Verizon and 31160. Is this an issue and if so, how can I select T-Mobile as the Network Operator? My apn settings are for T-mobile.
Thanks.
I have a Galaxy S9 (SM-960U) purchased from T-Mobile, but unlocked and running with an AT&T SIM (among others, at times). Up until today, the phone was running the stock T-Mobile ROM which received various software updates on a monthly or every two month interval. I've installed them as they were released (while running various non-T-Mo SIM cards) and the latest was October 1, 2018. Today, I clicked the "Software Update" function and saw that a new update was available. When it installed and restarted, I noticed that the phone was running an AT&T branded ROM, along with the typical AT&T bloatware (e.g., CNN, Groupon, Amazon, AT&T-specific apps) that was not previously installed.
The other thing I noticed was that the phone now is only connecting to HSPA and HPSA+ networks, whereas before it would also connect to LTE.
I'm not sure why I suddenly received and installed an AT&T-branded ROM today when my S9 and all of my previous devices were fine running the T-Mo ROM and receiving updates as they were released. Does anyone have any insights as to what caused this change and whether future ROM updates will be carrier-specific based on the inserted SIM? In the past month I've used SIMs in Vietnam and Japan and it seems odd that ROMs would suddenly be based on the carrier of the day.
Also, any ideas about restoring LTE service? I've tried removing the SIM and powering off the device a few times, but no dice. This was a network/account-problem when I initially ported over to AT&T from T-Mo which took a lot of troubleshooting at the store (unsure of actual root cause), but it seems odd that a software update on the device would undo that.
The latest update (3BRJ5) is BYOD firmware. With B firmware, a carrier sim will change the csc of your phone to match the network you are connected on. Good luck getting LTE back, I have no idea on that.
*#*#4636#*#* entered into phone dial. That will allow to select preferred network type in device information.

you have to change APN setting on the menu to reflect AT&T network. let me know if it works by changing APN.. I used to have S9+ tmobile and I was waiting for this BYOD update but i traded in my s9+ already =/ i have note 9 unlocked now..

The issue required a visit to the AT&T store, where they replaced the SIM and reset some of the network features on the back end of my account. This required a call to the retail technical support team and about 45 min. No settings were changed on the phone. The APN settings were already configured correctly (which I had confirmed as a part of initial troubleshooting).
The phone works fine now, though some features like AT&T HD Voice and the AT&T Call Protect app still don't work. I've tried contacting them twice about it and they opened a ticket but it hasn't helped. These aren't features I used before so I don't really care.

Keep in mind though that HD voice only available to postpaid At&t only not prepaid and they do required special sim card for hd voice but since you already changed sim card then the problem is not the sim card. You can try and dial #*#*4636*#*# and see if Volte is provisioned.. I wish i had my s9+ from tmobile but i dont have it anymore i was waiting for that byod software update.. Hd voice should work on BYOD custimization update on at&t
Just picked up an A5050U unlocked from ebay for my wife. I bought it, because it said that it can be used on Verizon. It says that it's unlocked for any SIM card. I moved the Verizon sim card over from my wife's old phone to the new phone, and it tried to activate on Sprint's network (we have Verizon).
I've tried to install the Verizon firmware from sammobile. When it goes through the initial setup it keeps installing the Sprint software. Does it recognize the CSC code as being SPR and contact Samsung servers and install the software? When it finally boots up, it says Verizon in the status bar for a second, then switches to Sprint, then to Preferred Network.
I can make/receive calls and texts from the phone, but it has a R above the signal bars.. and that whole activation thing with Sprint.. Any ideas on if I'm doing something wrong, or do I need to return this one and get a "Verizon" phone?
