Data roaming in Croatia is not working.

[Rachel27]

I am in Croatia with my pay monthly sim only iPhone 14 Pro. Data roaming is not working at all despite:

* mobile data on

* data roaming on - shows 4G or 5G on the Croatia networks in top right

* I did receive the ‘welcome to Croatia’ text confirming I have free roaming. Since then I received a very slow ‘E’ signal in the middle of a city but get absolutely nothing when I have an 4G or 5G signal and cannot connect to anything despite the above. My phone is a house brick. Everyone around me having no problems at all.

My travelling companion is on Giffgaff (which uses O2) and is working perfectly.

any idea what is going on? Will be switching away from O2 as soon as I get home if this can’t be sorted.

help!

@Rachel27 - 

Check your phone's APN, https://support.apple.com/en-gb/102483 , is "mobile.o2.co.uk" instead of idata.o2.co.uk (something was missed by O2 when your account was set up, and idata is missing on O2 side).

Make sure you are using 4G (5G should work too, but 3G most likely won't work any more).

Set your phone manually to a cellular network, even one that shows as "Forbidden".

Ensure you have Data Roaming enabled (as well as roaming).

Finally, contact O2 via Social Media or the free to call from an O2 phone +447860980202, to get them to check you have not got a Roaming Bar in place on your phone - seems many have had that setting inadvertently applied on new contracts over the last 2 years or so. You can also contact O2 via Social Media, links just below, use either one and ping them occasionally until you get an agent to respond.

Good luck, @Rachel27.

Rachel, I am having exactly the same problem with the same o2 account as you and a 16 pro. Mine worked perfectly on the 3rd July and 4th July became a pointless housebrick.  Navigating the 350 miles on a Croatian road trip yesterday was a nightmare. I too shall be leaving o2 asap. Absolutely hopeless service.

@-kim- - all the steps in my reply above hold true for you, with the added complication this week of asking if you use a physical SIM or an eSIM - O2 have been having major issues with certain eSIMs over the last week or so:

"...if you use an eSIM, to fix this you will need a replacement sent.

As you're logged into the Community you should be able to access MyO2 via the webpage rather than the app, link up at top of Community pages, so CS can send replacement eSIM over, however you can also visit a store with valid I.D.

eSIM - How to activate  "

Note as you are not in the UK, you may have difficulty getting the replacement eSIM to install, and may find you need to get a local SIM with adequate data for the rest of your trip (a PAYG SIM), and address the eSIM swap when you return to the UK. The 2 links below for O2's Social Media Team will help you to contact O2 privately for further assistance. Note that roaming networks are not directly under O2's control. Good luck!
