Unable to use mobile data while in Spain.

[Teddy1]

I was unable to use my mobile data while in Spain "you are not subscribed for this service" kept popping up.

This was a major problem as I was unable to open my covid vaccine app at the airport luckily I took a paper copy as a backup-I discussed with o2 live chat twice and was advised there was no issues with my account but there was as I have had no issues using data abroad in the past.

I would be very grateful for any advice thanks.

Some possible solutions:

1 - Reboot phone.
2 - Manually search for a different network
3 - If using an iPhone, change data apn to "mobile.o2.co.uk"
4 - 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.
