A phone that is blacklisted or locked to another network will not work on AT&T. Check the IMEI here before you buy it or switch.
Dial *#06# on the phone, or look in Settings, About.
We send a 6-digit code to confirm it, then your result. Use a real inbox.
No card needed.

Not until the original network unlocks it. The full report shows the lock status and the locked network for iPhones, so you know before you buy.
No. Slashtel is an independent service and is not affiliated with AT&T. Use AT&T's own compatibility check as well to confirm the model works on its network.
Dial *#06# on the phone and the 15-digit IMEI appears on screen. It is also in Settings under About, and printed on the original box. On a dual-SIM phone use IMEI 1.
Yes. Confirm your email with a 6-digit code and the result appears at once, with a copy sent to your inbox. No card is needed. Each email can run a few free checks a day.
For $1.79 the full report adds the blacklist history and, on iPhones, the network lock, Find My iPhone and iCloud status and the warranty, with a plain list of what to sort out with the seller. You are charged only once the report is ready, and not at all if it cannot be completed.
