LG Wireless Phone

I have at ATT Phone and want to use TMobile SIM Card. It's asking for unlock code. But from which company?

Which cell company should I get the unlocking code from?

1. Uh, AT&T.
2. There can be many ways to get your unlock code. If your contract period is complete you can ask your cellular operator for the unlock code. But, they do make it very difficult for you to get the code. You can also visit http://www.unlock-zone.com/ and can see different options there to get unlock code for a price. Choose any price appropriate for you. Hope this helps
3. the phone is locked to at&t....you'll need to get the unlock code from them. if they won't provide you one, you can purchase one here: http://gsmunlocklabs.com/att-network-imei-unlock-codes.html
