Is not working roaming in Europe

Hey guys, isn't connecting to the network whilst on data roaming with 3G connection in European countries. It works fine in the UK however doesn't connect in Europe and I've tried in 4 different countries so far. I haven't re-installed it yet as I have so much data on there to back up first. Any ideas? All other apps work fine whilst using roaming. Thanks

Some things to try:

1 - Reboot phone.
2 - Manually search for a different network
3 - Change data apn to "mobile.o2.co.uk"
4 - Check with O2 for any roaming bars.
If you message O2 on Facebook (https://o2uk.co/O2CFB) , Twitter (https://o2uk.co/O2CTW) or Instagram (https://o2uk.co/O2CIG) , they should be able to help you with this.

I’m having the same issue. Travelled twice to Spain on both times on Moviestar. When I make a call, it drops from 5G to 3G and then the call fails. 

I’ve returned again today and the same issue. Tried a new SIM, tried manually selecting the network, turned 5G off. It makes no difference. It’s like my phone refuses to use 3G for calling. I’m not sure why it’s dropping from 5G to 3G. It must be a network config as GibTel only drops to 4G  with no issues. 

Very fast data, but not able to make or receive work calls. iPhone 12 works fine. 

No bars on the AC
