No service

[Jayde]

I changed my tarrif and since receiving the email that the tarrif has changed I have no service. I have tried turning the device off and back on again and still no service. This is never usually a problem. What do I do?

Try removing the sim, clean it gently and reinsert. Reboot the phone.

If that doesn't work you may need a new sim. You need to call O2.

Numbers here Guide: Coronavirus Community Help and Support 

Advice from an O2 Guru regarding a way to get through:

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 an advisor.

Press Upgrade, Lost/Stolen or Fraud if you have to.

8am is the best time to call
