Why has O2 turned off my 4G calls?
If you’ve had a notification which says “4G Call Turned Off” you’re not alone.
The strange alert doesn’t exactly go into great detail about what or why this has happened either.
“O2 has turned off 4G calls on your account,” it simply reads.
This can be a little alarming and leave you wondering if you’re still able to make any calls at all.
“@O2 just had a notification to say you’ve switched off 4G calls on my account – why would this be?” one confused customer tweeted.
According to O2‘s response, it has something to do with a change in the network.
The firm has previously said: “A device does this check against the network every time it’s restarted, and one is done at 24-hour intervals.
