The mobile number to text me a code to verify my identity is wrong

[Andrea9]

When I try to log in, it sends a 6 digit code to a number to verify my identity, but this is not my number. So I cannot log in.

When the code is sent, you get the option, if more than one number is present, to select the number you want the SMS to be sent to.

If this is not happening, despite the correct number being selected, @Andrea9 , try the tips here Guide: Text Message Tips (not sent or received) and meantime see if the MyO2 app lets you get into your account - then check your details to confirm the correct number is registered. You can also add a second number if it helps, as here:

(Screenshots in there are from Web version of MyO2, this section in the app should work as well, from Account at foot of screen, then the easy-to-miss View all details from the next screen!)

Otherwise, contact O2 via Social Media at one of the ways in the link just below. Good luck @Andrea9 .
