Hello! I recently upgraded my phone (existing EE customer) from an iPhone 11 to 12. I moved everything over successfully, then followed the instructions to activate the new sim (type phone number and serial number etc). Despite this, the number has not transferred and I am unable to make calls/message from either phone now. Just wondering if I have done something wrong. The top right where it shows your signal is greyed out so cannot even ring to try and rectify the problem.
Many thanks.
