IMEI is short for the International Mobile Equipment Identity. It is a unique number to identify GSM, WCDMA, and iDEN mobile phones. You can find these numbers in several places, including its original packaging, the Settings menu, or dial a special lookup code on the dialpad. Here are the quick ways to check IMEI number on your Tecno mobile phone when you can’t find the its original box or the box label is missing.
Check IMEI/MEID number from dialer on Tecno phone
Open the phone dialer on your Tecno mobile, and dial *#06# A box should pop up with your IMEI number inside. If you saw two IMEI numbers on the dial pad, it means you have a dual-SIM phone, one IMEI/MEID number for each SIM slot.

Find IMEI/MEID number from Tecno phone Settings
Open Settings on your Tecno mobile phone screen, tap on My phone. Scroll down until you see IMEI entry on the screen to open.

If your Tecno phone supports two or more sim cards, you may find two or more IMEI numbers, one for each. I am using a dual-SIM phone mode, Tecno Camon 15, in the demo. Thus you can see two IMEI entries in the phone settings above.
