O2 data not working abroad...

Seen many posts already regarding this, but can’t seem to make it work. Data roaming turned on, APN changed to mobile.data.co.uk anything I’m missing? Every time I switch WiFi off I get hit with the ‘Could not activate mobile data network’ message, thanks

@Baaz  Please see this link: https://community.o2.co.uk/t5/How-to-Guides/International-Roaming-and-Whats-it-all-about/ba-p/309678

From the link: "O2 Contract customers may need to call 202 to confirm they have Roaming Activated on their account if they have never used the service before or had issues in the past."

Re: O2 data not working abroad...

Hi @Baaz 


If I have read your post correctly you're abroad at present, though you don't mention what country you're in.


As @Bambino has said you need to check with customer services that data roaming is actually activated on your account. You should also check there is no roaming bar on your account, as well.


From your mobile you can ring O2, free of charge, on +44 344 809 222 between 8-8:30am UK time to avoid a long wait on hold.


This is not O2 but a customer community and we, therefore, have no access to your account to check whether data roaming is activated and/or there is a roaming bar in place.


Good luck and welcome to the forum Welcome

Re: O2 data not working abroad...

@Baaz the APN to try is "mobile.o2.co.uk"

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.
