How to Fix an Invalid or Missing IMEI on the Alcatel 2012D If your Alcatel 2012D displays "Invalid IMEI" or a series of zeros, it won't connect to any mobile network.

1. Install MobileUncle Tools.
2. Open → Engineer Mode (MTK).
3. Swipe to Connectivity tab → CDS Information.
4. Select Radio Information → Phone 1 (SIM1).
5. Type:
   AT + EGMR = 1,7,"YOUR_IMEI_1"
   (Replace YOUR_IMEI_1 with the 15-digit IMEI from phone’s label)
6. Send AT command.
7. Repeat for Phone 2 (SIM2) with:
   AT + EGMR = 1,10,"YOUR_IMEI_2"
8. Reboot phone. Dial *#06# to verify.
