connection problems

[SandEClements]

I am in Cyprus and have registered on the Cyta Vodaphone network. Depite having a signal, when I make a call to a UK number it just keeps telling my no network connection? I have tried my wifes phone also O2 and she has the same problem. we also have a seperate Cyta sim which works fine, but O2 doesn't.

Some things to try:
Manually search for another network
Reboot the phone
Turn off 5g in network settings
If you have an iPhone change your data APN to "mobile.o2.co.uk"
If still not working then contact O2 to remove the Roaming bar on your account.

It may also be that you need 4g calling enabled on your account if the network you are using has switched off 3g.
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.

Try manually selecting a different network

You may need 4G and wifi calling enabled on your account
