Hello djrandee, welcome to the forum.
The 7100t is intended to be used on T-Mobile's network, and it's most likely carrier locked to T-Mobile.
If you want to use a Cingular SIM card in the 7100t, you must get the 7100t unlocked. Currently, there is no software available to do this, however if you have a T-Mobile account which has been in good standing for 90 days, T-Mobile will prove the Unlock Code to you free of charge if you ask them to.
Another route would be to send your phone to Bongo (www.bongowireless.com
) and pay them a fee to unlock the handset for you.
