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
Denied (Device no longer supported)! - Resubmit with premium
If your IMEI is not rejected instantly = it will most probably be unlocked!
