I have the D801 (I think that's it, the TMobile variant) and unlocked it to take it over to AT&T. We had to change the APN settings to get it to work of course. I am now wanting to sell the phone but would like to know if the Unlock still sticks, and if the APN settings were reset back to the Tmobile/stock settings?
The phone hasn't been rooted or anything of that nature, just the unlock code when I took it over to At&t.
Thanks!

The unlock will remain but the apn settings will most likely need to be re entered. I have the opposite situation(at&t d800 that I'm using on t-mobile)and I have factory reset this device and did the upgrade to kit kat and the unlock remained. I did have to re enter the apn settings after both the reset and the os update.

Excellent, thank you very much for the information. I wanted to be able to be a little more informed on that stuff before I try to sell it in case they ask. Appreciate it.

Guys,
I just had a quick question. Does anybody know if I do a factory reset on the phone, will it erase the SIM unlock that I did already from T-Mobile? My phone is extremely sluggish and locking up. However, Iam worried that doing a factory reset will "lock" the SIM again to T-Mobile. Any help is appreciated. Thank you!
You can unlock your phone as many times as needed with that code. The code is locked to your device!
It shouldn't remove the SIM unlock.
I have never tried with the Vibrant, but in me experience with about a dozen other unlocked GSM phones, a factory reset has never re-locked the phone.

Yup, same here.
unknown amount of odin's and roms 2.3 included, never a relock.
Factory reset doesn't even have access to that partition.
You should be able to factory reset with no issues. Once that unlock code is in, that phone should stay unlocked for life.
no, but I wish it does because some people with corrupted imei are having a hard time to fix it.
anyways, you'll be fine.

I have a Verizon Trophy that has been GSM unlocked (I use it on ATT). After a factory reset, CDMA mode is my only option. I can't even find a way to enter the unlock code again. Is there a way to re-enable GSM mode? Thanks in advance for any help
nevermind. I fixed it by flashing a custom rom on it. I still don't know why it was only cdma after the factory rest.

Where you using a default Verizon factory rom? That's just plan weird. The default option should always be Global Mode unless the SIM Card wasn't seated correctly.
yeah it was the original firmware. It happened after a factory reset. The option under cellular settings would not change to anything other than cdma. it possibly could have been related to the sim card. Who knows? I guess it just gave me a reason to flash a new rom.

Hello. Tell me please what ROM you use to unlock GSM?
Thank you!
I did the software unlock via the dial code & UMTS menu, I can make phone calls with a different carrier sim, but I cannot get the data to connect. I have been searching xda and google for months trying to get this to work. I have a Canadian Bell mobilty i337m. Stock rom (mdj) and its rooted. I have tried factory reset several times but it doesnt fix it. I also tried flashing back to stock with odin. Does anyone have any other ideas?
When I try a telus (or other provider) sim, it give me voice service only and in the about > status menu the mobile network state either says disconnected or connecting. I have the data toggle on also.
Those unlocks don't work that well with the Canadian variants. They're designed for the i337 not the i337m.
Have you made sure the apn is set up right for the carrier?
Maybe this will help
Code:

I will say the reason that cause the problem is that this is an ATT phone with At stock ROM. So it doesn't have the APN setting for other carries. You should set that by yourself.

Not true. I successfully unlocked my first S4 I337M on Bell following this tutorial. I sold that one because I was able to make a profit once I unlocked and flashed the AWS mod to make it compatible with WIND and Mobilicity.

Try reflashing the original 4.2.2 firmware from here and then immediately follow this tutorial before rooting (do not install any system updates!). Then you can root, install custom recovery, reset the flash count, etc.

You did exactly what I am in the process of doing. I will try what you suggested now. Thanks!
Also, ive manually inputed apns for telus and eastlink and neither seem to work. I can always make voice calls, but the data will not connect.

oddly enough, when I put a telus sim in it and waited for a while (in hopes it would eventually connect to data) and the apn settings for telus were in the phone. I know I didnt put them there because the apn settings for koodo were also present along with a third apn that I cant remember.
For future reference, try not to double post. Just edit your current post.

It's actually not an odd thing to happen. Once an activated SIM is inserted and the phone is unlocked, the phone searches for the best APN settings from all compatible carrier bundles. Some phones do this more accurately than others. However, it may not do this well enough if a custom ROM is installed. I know this to be true because this happened with my older Galaxy S3 when I tried selling it to someone (it was a T-Mobile unlocked running CM 10.0 at the time). However, setting the APN manually (assuming all settings are correct and that nothing else is wrong with the phone) should resolve your issues.
If you're still having problems, I suggest doing these things:
1. Try going into your network operators and let the phone search for carriers nearby. Once the list shows up, tap on Telus and wait until that screen closes on its own.
2. If you can't get data going yet, try disabling it, re-enabling, and reboot.
3. If this still doesn't work, try going into the network mode screen and select GSM/LTE and reboot.
4. If it's still derping on you, then it must either be your SIM not connecting to Telus's data network, or your account has a data block. That's all I can really think of.
Good luck.

Ok, reflashed stock 4.2.2 (the first one) and manually entered TELUS apn settings from the telus website, got data to connect finally. As a note, there was a typo in the apn settings that it auto aquired for telus. Going to try a eastlink sim tomorrow and hopefully AWS is working.
Edit: all seems to work. thanks everyone!!
OK, I finally got Sprint to uicc unlock my phone yesterday. Now I need to figure out how to change carrier options., any help would be greatly appreciated. Also now that it's carrier unlocked shouldn't I be able to access the hidden menus and stuff or can I only do that after root?
No getting unlock didnt change anything. It just unlocked the uicc slot for a different sim. Have to get another sim and pop in phone and then you can set ur apns for that network.
Nothing else gets "unlocked" and is nothing near the access root gives you.
That's what I thought ugh. But I've tried to do that and can't get the APN to save.... I've tried to edit it with##debug# I have my msl also. And I also like I idiot purchased a unlocking app off eBay and all it was is hidden menu apk. You can add APN with that but still don't save. I inserted my Verizon sim card in the phone and it shows me roaming for service. I'm going to root my phone hopefully tomorrow afternoon. Once I do that the way I understand it that I'll be able to change and access more things. Sorry I'm a newbie when it comes to rooting, can do a lot with phones but some stuff is all new learning experience

Dont need to root.
If you have msl you can use cdma workshop or another efs program. Need to change ur prl to a vzw one. Then set apns.
Root will fix the issue with apn not saving as the hidden menue stuff needs root to activate the right menues.
But you should be able to swap prl to vzw one and put in sim and do *228 to activate. But rooting will make easier.
Root and flash a vzw rom and profit instantly lol
Quick question? i have the vs997 and i rooted and flashed the vs996 to utilize my Verizon sim. I am able to access and edit apn settings, lte and such work fine but are you saying i could flash a verizon rom to this vs997 so i dont have to use the vs996 rom with the debug kernal?

OK I'm want root also cause I want to tinker lol, I love messing with the different menus and stuff. I'm kinda nervous to root cause will be first one and don't want to make expensive paper weight.... But I ran into some issues the other day with trying to root but didn't know needed SD card and couple other things. But like other guy said I can flash the VZW ROM and be golden? Also will I pick up all the band's that VZW towers put out?
I bought used S8 that had clean IMEI (not blacklisted), it was locked on Sprint and with financial eliglibity. Before I got it unlocked it didn't recognised any sim card, after unlocking it did regular setup on my ATT card with all the ATT apps but it doesn't have service. Then I tried with Verizon SIM and it did the same, regular setup but no service. What do you think what's the problem ?
Phone build number : R16NW.G950USQS3CRE2
Is it rooted, and if it is, have you uninstalled any system packages
If not, try a factory reset and making sure the sim is active and APN settings are working and you have chose a network

It's not rooted, I did remote unlock with unlocking service and they flashed original firmware on it, nothing should be messed up.
I did factory reset few times as well as network reset. I double checked APN info and ofc it's setted up together with card.
I forgot to mention that phone is not showing up IMEI, actually nothing when I type *#06# in dial
that mean you lost imei ....flash factory firmware by yourself...it will do the trick

Can you explain me which one I need ? What about bootloader, is it the same ? I've checked thread about bootloader and mine is "carrier firmware", not unlocked.
Which career search for career. Look at the build number in abiut and search for that.
I'm using ATT and my phone was locked on Sprint, so I flashed Sprint firmware and It's the same. I put the SIM card in, it did ATT setup and all of the apps from carrier but it's still block sign instead of signal sign in top right corner and airplane mode is light blue (not usual blue like when you turn it on)
At least this time it's showing up imei in dialer
I couldn't find ATT firmware, if someone knows there's my build number in first post.
