You need to Unlock Sidekick LX model from T-Mobile network lock.After Unlock it use with any GSM Network Sim card...you can Unlock it easily using the unlock code from Online sites...You can get the unlock code at Onlinegsmunlock.com/sidekick-lx/rs7wp9/
and Unlock it easily.Then use with AT&T Sim card..You can use all Features that in the Phone.
