Roaming in Europe not working

[Hutchables]

Good evening all, I’m away in Europe at the moment and my roaming doesn’t seem to want to connect to the local network, I have all the settings correct and the relevant bolt ons.
It will briefly connect to 4G but won’t show any signal bars, this last about a minute before it goes off and shows up as no service.

This is frustrating as a few of my work colleagues are on O2 and have had no problem connecting.

Any help would be greatly appreciated as I need to use my phone while I’m out here and there is no Wi-fi where I’m staying.

First step is reboot your phone ,you may need to do this a couple of times. Are you friends on O2 also? I’m asking as O2 have been slower that other operators to sign up for 4G roaming cross agreements with other providers.

I have tried resetting settings, turning phone on and off countless times.

Turning airplane mode off and on will connect to 4G for about a minute before it disconnects.

My friends are all on O2 and have 4 bar signal and 4G, this is irritating as I need to use my phone while over here.

To help others give suggestions can you say which phone model you have?

iPhone? 

Change your data APN to mobile.o2.co.uk

Also, o2 have about 3 agreements to use 4G so it might be that where you are they do not use it...

Try switching to 3G and see if you can get a connection.
