Every mobile device has a unique IMEI number. Here is how to find it on the most popular platforms.
Dial *#06# on the phone keypad. The IMEI appears immediately — no internet needed. Write it down or take a screenshot.
Devices with two SIM slots have two IMEI numbers (IMEI 1 and IMEI 2). Check both when verifying device status.
Once you have the number, verify it instantly at uapi.relock.net.
