When abroad is america difficulties with maintaining signal and Internet access, phone is saying that there is Internet connection despite showing 4G or 5G

Have you tried a manual rather than auto network selection?

See if changing network helps

@Lele 

Some things to try:

Check data roaming is on in phone settings.

Manually search for another network. Try T-Mobile and AT&T.

Turn off 5g

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

Check with O2 whether you have a roaming bar on your account. Do this via social media

If you message O2 on Facebook ( https://o2uk.co/O2CFB) , Twitter (X)( https://o2uk.co/O2CTW) or Instagram ( https://o2uk.co/O2CIG) , they should be able to help.
