How to Fix Invalid IMEI on my TECNO Phone

What causes “invalid IMEI” to show on your TECNO smartphone’s display could be a variety of issues: 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 — which means International Mobile Equipment Identity — is that unique 15-digit serial number every GSM cell phone carries. As you might have guessed from its name, an IMEI number is used by GSM service providers for identifying your Android mobile phone.

But 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.

Fortunately, this post explains “invalid IMEI number” solutions to help nip the issue in the bud.  It’s a step-by-step guide on how to change IMEI on TECNO smartphones, covering areas such as how to fix invalid IMEI on TECNO phones, how to fix invalid IMEI without root, and related issues.

How can I solve the invalid IMEI problem on my TECNO phone?

The method explained in the steps below on how to fix the issue of invalid IMEI on TECNO works for almost all phone models from the maker.

Before you proceed, consider enabling developer options in Settings. Let’s get started:

  • Dial *#06# to know your current IMEI number (you may write it down somewhere)
  • Download the MTK Engineering Mode app from the Play Store
  • Launch the mobile app
  • Tap Connectivity > CDS Information
  • Select Radio Information
  • If your phone is the dual-SIM type, click on Phone 1 and then Phone 2
  • If it supports a single SIM, then tap on Phone 1
  • In the next menu that shows up, put a space in the (AT+) bar, and delete the space
  • This brings up a tab, where you click on AT+EGMR=1,7’’’
  • Put a space in AT+EGMR=1,7’’’
  • Tap Send AT command
  • Restart your Android
  • For the IMEI number of SIM 2, go to Phone 2
  • Tap AT+EGMR=1,10’’’
  • Put a space in the code
  • Restart the phone

Having completed the steps above, you can now dial *#06# again. You can also find the IMEI number in Settings or at the back/front of your phone’s battery.

Your IMEI number should now be valid. In this technique, we’ve highlighted how to fix invalid IMEI without root.

Step-by-step guide on how to change IMEI on TECNO

If the method above doesn’t work for your specific TECNO phone model, you can give the procedures explained below a try. Lots of Android users have this pertinent question on their mind: “Can I change my phone’s IMEI number?” If you’re one of such people, note that you can do so.

In this section, we’re looking at two methods for achieving that aim. One of the simplest procedures for fixing the invalid IMEI issue is to change your phone’s IMEI.

Method one: Using dialing code

With developer options still enabled from the method above, you can proceed as follows:

  • Dial *#*#3646633#*#* or *#7465625#
  • This operation takes you to EngineerMode
  • Tap Connectivity > CDS Information
  • Select Radio Information
  • If your phone is the dual-SIM type, click on Phone 1 and change the first IMEI number
  • You’ll find a place to enter the code: AT+EGMR=1,7,” IMEI 1”
  • Copy and paste this code there
  • Reboot the device once you get a response saying the command is successfully sent
  • Go to Phone 2 for the second IMEI number
  • Copy and paste this code: AT+EGMR=1,10,” IMEI 2”
  • Restart the smartphone

Method two: Using the app

Some TECNO models don’t support the use of the dialing code in the first procedure for changing IMEI without the root above. This second method should work effectively for these smartphones:

  • Launch the MTK Engineering Mode app downloaded earlier
  • Tap Connectivity > CDS Information
  • Select Radio Information
  • If your phone is the dual-SIM type, click on Phone 1 and change the first IMEI number
  • You’ll find a place to enter the code: AT+EGMR=1,7,” IMEI 1”
  • Copy and paste this code there
  • Reboot the device once you get a response saying the command is successfully sent
  • Go to Phone 2 for the second IMEI number
  • Copy and paste this code: AT+EGMR=1,10,” IMEI 2”
  • Restart the smartphone

NB: Changing your phone’s IMEI number is a punishable act if you alter it to that of a stolen device. In many countries, modifying an IMEI number is illegal, but it isn’t in Africa and Asia. However, note that changing the number is likely to damage a phone.
