Roaming not working in Reunion Island (EU)

[Ajondyh]

I am in Reunion which is listed as EU with O2 and can’t get mobile roaming. Have changed settings as suggested on here and by O2 in the help but still nothing. Using iPhone 8 Plus with sw 12 version. Any help appreciated

@Ajondyh make sure data roaming is on and try both apn's 

"mobile.o2.co.uk" and "idata.o2.co.uk"

Also try manually selecting different neyworks.

Also check if you have a roaming block on your account

Tried everything you said apart from data block. However I was in Malta last month and it worked ok. Thanks for reply though

Most likely an isolated issue which may just resolve itself without any interaction from yourself then.
Just reboot the phone occasionally to refresh the network settings.

This isn’t an isolated issue I know numerous people who have had the problem with O2 & Iphones in Réunion.

Yet to find a solution that works, changing the apn and trying different networks does not help.

Any other suggestions?
