Can't seem to find this answer. If I bypass the SIM unlock part, unlock my bootloader and load a custom ROM, like LOS or crDroid, will the new ROM overwrite the SIM lock? Could I then use an international SIM (I live in the US) when I travel abroad?
T-Mo is giving me the run around cause I'm not a T-Mo customer, saying they won't SIM unlock for me.
Here's how I did it: Settings -> About Phone -> scroll down to Network Unlock -> hit Continue (mine's unlocked already so I only see "Continue" or "Cancel" for a brief moment before it says, "This mobile device is permanently unlocked and can be used with any carrier!" Also I was not a T-Mobile customer when I unlocked this phone (never have been) and did this over Wifi in another country. I didn't have to contact T-Mobile either. I recommend trying to unlock it from the menu because it seems a lot easier than attempting a bypass.
Is the phone giving you some kind of message/error when you attempt to unlock using this method? Or are you attempting an experiment with the phone for research/discovering additional SIM unlock methods?

First of all, Hello
I have a HTC Touch HD which is locked in Vodafone (i am from Romania).
I have used the SIM Unlock program that this site provides for contributing members and i have a problem:
I have followed all the steps and i have unlocked my phone but when i put an Orange RO SIM, it cannot register in the network, even though if i try with another SIM from another carrier, it works.
My question is: is there a way to revert the phone to its locked status like it was before i used the unlocker?
I have an 1.3 rev Samsung Focus. It was an unlocked model I got from outside. I was in the US at the time of Mango update and updated my phone with Mango from AT&T. Now I have moved out of the US and want to unlock it. AT&T doesn't have the unlock code because I didnt purchase it from them. Any Ideas on what I can do? Will a custom ROM help me with Unlock? When I check lock status, it is SIM Lock is Disabled, only Network lock is enabled.
I'm not sure what you meant by "It was an unlocked model" in the context of "out of the US and want to unlock it". Was it unlocked or locked? Anyway:
Read the wiki, (carrier) locks are in NVRAM, no relation to flashing whatsoever, so any custom ROM won't SIM unlock your phone.
Have you tried ebay? Unlock is cheap as $1 and it doesn't hurt to try (unlock via IMEI - I unlocked AT&T and Rogers Focuses). If that fails, I recommend fastgsm, I've unlocked my own AT&T Focus with them, via USB (no affiliation).

It was carrier unlocked, as in I could place any sim in the phone and it would work. After I updated it on my Zune with Mango, it was loaded with AT&T's version and hence locked to AT&T. Now AT&T doesn't have the record of the IMEI in their database and aren't able to provide me with an unlock code. They were able to provide the unlock code for my other windows phone that I purchased from AT&T. Thereby lies my predicament. Let me try the ebay version, if not I hope FastGSM works. Thanks.
I was not able to get the unlock code from ebay. But FastGSM seemed to work wonders. I used their USB unlocking tool and it worked just fine. Thanks for the tip.
Hi All - I recently bought a Samsung Galaxy S8 from someone else. It worked fine when I was with T-mobile but when I moved to another network and popped in a new SIM, it asked me to "Enter network unlock code". I figured it must be locked to T-mobile so I reached out to them. They said my account met all the unlock criteria and said they'll send me instructions via email. I got the email two days later saying I need to use the "Device Unlock App". However, there's no such app on phone and there's no way to install it either (its not in the Play Store). I went back to T-mobile and they said since the device wasn't purchased through T-mobile, its not be a T-mobile "branded" phone. My questions are:
1. If its not a T-mobile branded phone, why does it only work on the T-mobile network? I checked its not rooted. It doesn't have any T-mobile apps and doesn't show any splash screen with the T-mobile logo.
2. Someone said that Samsung GS8 locks to the network of the first SIM you put into an unlocked phone. Is that true?
3. T-mobile says they've "whitelisted" my IMEI, so if I can somehow get the Device Unlock app I may be able to unlock it. Any idea how I can do that? Do I need to flash the firmware and install the T-mobile version or is there another way.
Thanks!
If you need to app, you can try here: https://support.t-mobile.com/docs/DOC-14011
However, as your phone is asking for the unlock code, the app might work but not unlock your phone.
You really need to do a network check and see which network is your phone actually locked. If your phone needs unlocking code, you might need factory level codes.
I think you should visit :

hi, i just got my (second hand) nexus 6p and so far i like it alot.
updated to 8.1, unlocked the boot loader, installed twrp amd magist to get root all working fine.
the phone seems to be locked to vodafone (uk) as it works ok with a voda sim but when i try a ee sim or 3 uk sim it will not register on the networks and says emergency calls only. the thing thats confusing me is that it does not ask for a unlock code when i try another network sim, every other phone i had has always asked for a code to unlock it. am i missing something or is there another way to input a unlock code if / when i get it from voda or a third party unlocking provider?
cheers / thanks
You might be right but the solution is there check out this page https://support.vodafone.co.uk/Usin...one-device-if-I-m-not-a-Vodafone-customer.htm
thanks to a message from Exodusche my problem is solved. the phone is not network locked at all, when changing the sim for some reason i had to turn off the security pin then reboot the phone and as if by magic after that i had service and everything working fine. some sort of glitch in 8.1 i guess.
Soooo I have a N20U via T-Mobile and obtained a Sim Network Unlock code. Tried to use another carrier's sim card to enter the unlock code when prompted and was directed to the Network Unlock in the Mobile Network settings. I chose permanent unlock but T-Mobile wasn't going lol. Denied! Is there not a way around this to sim unlock the phone without going through T-Mobile??
Thanks for the help
