I have exactly the same problem with PAC code and EE number not not transferred by THREE despite their repeated promises that it will be transferred without any problem!! The man at THREE retail in Sutton, implemented the transfer from EE to to THREE(...allegedly). He Promised me that my EE number will be transferred to my new mobile no problem. My EE number has disappeared.
BTW broadband sim installed by Three retail Sutton stopped working after a few days. I lost many days and hours trying to get help from THREE to sort it. This is not reliable nor helpful THREE service.
How can I get Three to get and install my old EE number. I have heart condition and have a pacemaker. My the NHS, my GP, hospitals and doctors have my old number. They cannot contact me nor text me with appointments and other medical details. I need my old number back. Without it THREE have placed me in a dangerous medical situation. Thank you.
