My device was showing 'sim failure' this morning. I tried turning off my phone and back on again and also tried my sim in another device, which also said 'sim failure'. I am unable to call customer services, as I have no network. What should I do?

Hi @hughbert32
Sorry to hear you are having issues with your sim card. Please see the guide on alternative ways to contact O2. Guide: How to find help & contact O2
Hope this helps

Download Skype and call any of the free numbers and press any option
The 4005 number seems to give best results
