AT&T USA - Apple iPhone "Out of Contract & Clean" Source B

What's especially interesting with our service is the INSTANT rejection of Unsupported IMEI with comprehensive reason provided with our API:

Denied (Non AT&T IMEI)!
Denied (In Contract)! - Resubmit with premium
Denied (Lost or Stolen)! - Resubmit with premium
Denied (Active on Another account)! - Resubmit with special service
Denied (Recently Upgraded)! - Resubmit in 14 days OR Resubmit with premium
Denied (Not following guidelines)! - Resubmit with premium

If your IMEI is not rejected instantly = it will most probably be unlocked
