I’m currently roaming in germany with a Fairphone 6 and a Shift 8.1.
Both are using O2/Telefonica SIMS.
The Fariphone is having no problem connecting to 5G whilst the Shift can only manage an Edge connection. It shows it has a data connection while reporting there is no roaming internet access.
Can anyone help please?
If physical SIMs, try to swap them and see if the issue is coming from the device / config, or the carrier.
I was here a few weeks ago with the same SIM in my old phone (OnePlus 10 Pro).
That was working without issue.
I have looked at the APNs and polled round those showing as available for selection.
One or two of the APNs briefly show data coming up. But after a second or so, this drops.
In all cases the data connection edns up as EDGE.
