Most times, you might forget your phone number not because you don't know it but maybe as a result of too much thinking. Or you bought the Sim card new. Whichever way, in this post, am answering questions like how do I check my phone number on Glo, Airtel, MTN and Etisalat.
Dial *663# or Dial *123# and follow onscreen process that follows.
Simply dial *248# and your number will be displayed.
To check and know your mobile phone number on Airtel, dial *121#
Follow the onscreen instruction.
Dial *135*8# on your Glo enabled phone and your number displays on your screen.
