Won’t connect using mobile data when WiFi is switched off

[K8]

Can anyone help me? In the current climate I can not get to speak to someone at o2 as my problem is classed as none urgent.

Over the past couple of months...when I turn my WiFi off my mobile connection doesn’t seem to work. I still have my full allocation of data left so it is definitely not an issue of buying a bolt on. I have tried turning the mobile data and WiFi on and off and turning it on to flight mode and back off. Also switching off/on and taking the sim out.

I have never had problems prior to this.

Any suggestions of what to do would be greatly appreciated.

Many thanks

Hello @K8 

No expert me!   just a thought 

Have you gone into settings and had a look?

@K8 

Have you tried your sim in another phone to check whether its a sim issue?

Have you checked your network status? https://status.o2.co.uk/ 

If all ok then I'm afraid it is going to be a case of calling O2.
