Some things to try:
1 - Reboot phone. (or toggle airplane mode).
2 - Manually search for a different network
3 - If using an iPhone, change data apn to "mobile.o2.co.uk"
4 - Turn off 4g (use 3g)
5 - Check with O2 for any roaming bars.
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.
I have no affiliation whatsoever with O2 or any subsidiary companies. Comments posted are entirely of my own opinion. This is not Customer Service so we are unable to help with account specific issues.
Please select the post that helped you best and mark as the solution. This helps other members in resolving their issues faster. Thank you.
