how does o2 expect us to login if there is no phone signal

[slowsandal]

o2 now require a code to be sent to your phone to log in, there is no option to send it to email, if there was no signal how would i login, this would also make it impossible to manage my account if i was using my sim in a router for example

You can add another number @slowsandal - this post

https://community.o2.co.uk/t5/My-O2/The-code-you-send-me-is-to-the-wrong-mobile-number/m-p/1730103/h...

has examples and shows you where to access this hidden feature.

If you cannot access App or Web MyO2, then you would need to engage CS, Social Media Team links all in the link just below 

Good luck!
