I'm traveling to Ireland from the UK at the moment and my mobile plan isn't working anymore. For the first few days everything was working fine, texts, data, the lot. Everything is now not working, and when I go to call customer service (4444) my phone says I am not registered to a network. I've still got tariffs, and my data roaming is turned on. What could be the problem?

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.
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.
