What causes “invalid IMEI” to show on your TECNO smartphone’s display could be a variety of issues. For instance, using the device after a factory reset on it, flashing your Android with the SIM card left in it, and others. Sometimes, the culprit might be a problem in your Android’s MTK setup.
IMEI contains 15 digits unique serial numbers for every GSM cell phone. When your device displays the “invalid IMEI” error message, you find out that you can’t make or receive phone calls and can’t send or receive text messages.
