Have just called EE for the third time. I’ve now been told to put the EE sim in my phone and I’ll be without my number for 24 hours until it transfers. Unfortunately got cut off before EE could fully check my account out.
Not sure why the first two people didn’t say that. One told me to wait until I got an email to put my sim in. Then another told me just to wait until my plusnet sim stopped working.
