I called ATT and gave me my unlock code for my Motorola Atrix. I used a Tmobile sim card, entered the code. And it said Network unlocked successful. So do I need to enter the code every time I use a non-ATT sim or it is unlocked forever?
And if I do an update, would it still be unlocked, or would I need to re-enter the code.
Thanks.
It is permanently unlocked.
Your good to go
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.
I have a Samsung SGH-i437 that was a contract phone from AT&T. I wanted to unlock it for use over seas, so I rooted the phone and installed CyanogenMod cm-10.2-20130925-UNOFFICIAL-expressatt but the phone still has a carrier lock on it. I now have a unlock code but can not get the prompt by using #7465625*638*CODE# because it give me a no network message. When I insert a different sim it does not recognize it. It only has the icon for the sim with a ? make on it.
Any help would be appreciated!
Got an unlock code from AT&T, but I can't seem to be able to get to the point where I can punch it in and unlock the phone (no, I do not have a SIM card). Any advice? I tried a bunch of codes to get it to unlock mode, none works. Currently running CM13 on my 1337.
Many thanks!
In order to be promoted for sim unlock code or to enter the unlock code using the dialler menu, the phone needs to be running a stock or close to stock rom with the stock dialler.
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
