Sim not swapped after 24 hrs

[JMB]

Hello,

I have upgraded my phone and due to it being 5G ready i needed to use a new sim,

I used the website to swap my sim and typed in my new sim code but now both my phones have so signal and i cant receive or make calls and text.

Your live chat isnt up due to COVID and i understand, i cant call a support line as i have no signal so not sure if they are open and you dont have a contact email on your website so this is my last shot.

Thanks,

Jake

You need to contact O2.
All numbers are in this guide including Skype Guide: Coronavirus Community Help and Support 
When you call, you will be asked for 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.
You can also try saying "Upgrade" or "Fraud" to be connected to an advisor.
