Roaming with O2 - country specific issues

[w1bbles]

I previously had an iPhone 7 on O2 (contract) and it roamed no bother in France, Netherlands, Abu Dhabi, Qatar, Dubai, Hong Kong, Singapore, China.

Took it to Dublin - nothing doing. O2 say nothing wrong their end.

Upgrade to iPhone 8. Exactly the same problem.

Change SIM to eliminate that as an issue (keeping same number).

Upgrade to iPhone XR. Not been away with it since I swapped the SIM. In Dublin right now. No mobile signal. Live chat with O2 using WiFi... def not a problem at their end. Must be mine.

It won’t work on auto or manual network selection.

Any ideas please?

Any apps available to verify cell signal strength etc? Could it be that you've been unlucky enough to land in a signal blackspot?

Have o2 confirmed given your location during a web chat that 3G/4G services are available?

Given your roaming abroad without issue I can't believe its a phone or account issue.

I would try all the local networks to find one that works.

Dy default when roaming, the phone will latch onto the first one it finds - which may not work.

Sorry don't know how to do this on iPhone.

Should probably go onto Three as that's who took over O2 in Ireland.

It’s happened three times (i.e., three separate trips to Dublin, two overnight and all in different parts of the city).

I’ve tried manual network selection for all the available options, including 3.

I ended up tethering to my EE-powered iPad this time. At least I could get emails and WhatsApp calls.

Anyhow, just landed at Gatwick and I have full 4G service again. Bizarre.

When you're roaming it should latch onto the strongest signal at any time.

I had this with EE in the IOM and they eventually resolved it by pushing through some information or another, it took a getting up to the second tier of support though, the front line guys didn't have a clue.

I get this every time I go abroad, to rectify I change the mobile data APN from idata to mobile and it always resolves the issue.

Interesting... just the idata.o2.co.uk bit in the top level ‘CELLULAR DATA’ box?

What exactly do you change it to please?

Yes just the first line - mobile.o2.co.uk

I was in Dublin from Monday until yesterday and my O2 phone worked perfectly from landing at Dublin airport, as did the missus' phone.

If you've swapped handset it surely is a SIM or account issue?

You’d think so, wouldn’t you?

But not according to O2.
