Fix and solve invalid IMEI issue due to no signal and network on your Android device with this useful method for Mediatek phone
Incorrect IMEI is a common problem faced while installing a custom ROM or updating your Android device. This issue mostly occurs with MediaTek based Android smartphones. Due to the problem, the network is not recognized by the SIM card and the SIM does not show any signals or network.
Here I have come up with two ways to fix the problem.
Method 1. Assign IMEI number
- Rooted Android Phone.
- You need to know the IMEI number of your device.
- Dial *#06# on the dialer.
- You can check for IMEI in About phone under Settings.

According to 6 Once done you will see the network.
Note: If the command does not work, simply put The space after AT means AT +EMGR Instead of AT+EMGR.
