I have a T-mobile Vibrant that i need to unlock for ATT but it doesnt want to unlock. Ive searched multiple ways to unlock it but they all seem to require a tmobile sim card which i do not have.

Try jocky's security unlocker, theorically it should remove SIM lock with all other security stuff.

SIM Unlocking phone on MIUI

hello everyone,
been out of the scene for a while, and I just sold my dell streak, however, the new owner cannot use his new dell streak as its locked to AT&T. I obtained an unlock code from them by calling them, but the streak is on MIUI and the menu that ask for the unlock number does not come up, is there any other way to do this? do I have to flash an original android firmware to it? Thanks in advance.

you said it is sim unlocking... therefore (usually) it is phone related locking... not from at&t... there should be a menu for security > sim card lock
im just trying to unlock the phone to be used with TMobile, it is locked to AT&T not sure if it's phone or sim. AT&T gave me a code to unlock it but when I insert the sim the menu to unlock it doesn't pop up

open Settings > Security and search for something similar to sim card lock... you should get something from there...
if you get nothing.. most probably the phone is network locked... my phone is network unlocked where i can insert any sim... and it does have sim card lock in case there is someone else want to use the phone and use another sim card in it...
If you mean CARRIER unlocking and not the sim card itself, you have to install a stock rom. Sim unlocking isnt exactly something that can be easily tested on a custom rom, so that's your only reliable way of doing so.
If you mean the actual sim card itself, cant help ya
anyone care to share some rom links, all the ones ive tried dont work or a whole bunch of ads come up.

[Q] Difference Between Unlocked and SIM Unlock

Hi,
I have a noob question. When you unlock bootloader, that's mean is SIM Unlock or it's completly different ? I know SIM unlock is to go with any phone company.
Thank you.
Completely different things. With the bootloader unlocked, you're able to install custom kernels, but the SIM Lock will remains (if you have it).

[Q] SIM Unlock on Custom ROM

I got a SIM unlock code from Tmobile, however it is not working with CM10, so I went back to the RUU and tried and it still didnt work. Any ideas of what I need to do?
contact the person you got the unlock code from to re-enter the code.. or you can always s-off your device and use the unlock sim for s-off method which would disable the sim lock on your phone
