Changed tariff - Lost signal

[DavidB286]

I have upgraded my tariff this morning and kept my existing SIM. However since I completed the upgrade I have had no signal. I have tried removing & re-inserting my SIM and rebooted my phone but this has not worked.

There was no mention that I would experience a loss of signal when I performed the upgrade

We’re just customers like you but it sounds like you’ll need someone to access your account which can’t be done from here. If you message O2 on Facebook (https://o2uk.co/O2CFB) , Twitter (https://o2uk.co/O2CTW) or Instagram (https://o2uk.co/O2CIG) , they should be able to help you with this

Thanks

The same has happened to me. It’s a joke. Can not get thru to them on the phone or by message. Have try Facebook my o2 and other social platforms. 
I will be ending my contract once I have finally spoken to someone.Customer  service is a complete job
