Swap over

[Clairet]

My old EE number was meant to change over but this has not happened yet, have restarted phones but still nothing?

Use Skype to call any of the free numbers in the link

Guide: Coronavirus Community Help and Support 

You need to call customer service
Advice from an O2 Guru to get through:
If you call 202, when it comes to the reason you are calling stay silent for 15 seconds and you will be taken to the keypad options.
Press 2 for Everything Else
Press 5 for More Options
Press 7 for Anything Else which will put you though to someone.
Choose the fraud option if necessary

The process starts with your EE sim turning off.

Once it has, keep rebooting your phone with O2 sim until it comes online. It can take up to 24 hours.
