Why would I need to look up my phone number?

You might want to look up your phone number if you don’t have a record of it, or if it has simply slipped your mind, but you need to pass it on as one of your contact details.

What if I have dual SIM cards on my phone?

If you’ve got two SIMs in your phone, then both phone numbers should be listed in the About Phone menu, as ‘Phone Number (SIM slot 1)’ and ‘Phone Number (SIM slot 2)’ as shown above.
