Hi I've signed up with a sim only deal and asked for my old number to port across today. New SIM in phone - great! Trying to register on app but I'm being asked to provide a security code, which I don't have. I've requested one which has been sent to my phone by text. But I'm not receiving the text cos the phone isn't registered to the network - either the original number or my old number.
Help!🤷♀️
