Roaming issues!

[Joe29]

Landed in Kos, Greece on the 8th June 2025. Plane landed, turned my data back on and roaming. Within a few minutes I received a text from O2 stating I had access to my data etc etc just like normal. Since the 13th June my 5g signal has completely cut off and I have no access to any form of signal/data. I haven’t touched any settings it just stopped working. Does anyone know why this is?

We are a community of customers here so can't advise on that.

Generally

Manually search for another network

Make sure 4G calling is on

Turn off 5g

Change your data APN to "mobile.o2.co.uk" if using an iPhone.

Check with O2 whether you have a roaming bar on your account. 

Do this via social mediaIf you message O2 on Facebook ( https://o2uk.co/O2CFB) , 

X Twitter ( https://o2uk.co/O2CTW) or Instagram ( https://o2uk.co/O2CIG) , they should be able to help
