Roaming not working

[kitenski]

My wife is currently in France, the first time she has been abroad since she switched from 3 to O2 and data roaming isn't working.

She gets a connection, can send SMS and ring me, but get's no data. She connects to the network and can see 5G at the top of her iPhone.

We've reset the network settings, and mobile data and roaming are on. I've a case open with O2, but was just checking my APN which is set to idata.o2.co.uk with a username of vertigo (my phone has been working fine). Is this APN correct? from searching on here I see it should be mobile.o2.co.uk?

She's got data now, so thanks! Do you happen to know if I can get the O2 carrier settings resent at all? Can't see anything from myo2 on the web.

They should update automatically when the phone reads the sim card @kitenski 

You can try a hot sim insertion but probably best done when in UK and connected to O2-UK network.
