Mobile data doesn't work: Error activating /ril_0/context1: org.ofono.Error.NotAttached: GPRS is not attached

@kugiigi I'm not sure if I understand your question correctly. When mobile data doesn't work, the only effect is that the button for mobile data moves to green. Beyond that I cannot see anything happen.

@Martin5 What happens when mobile data don't work? I'm actually having an issue on mine too and turning on mobile data will just change the Wifi icon to something like it's trying to connect but never connects. However, there are times mobile data works fine. In my case, there are multiple possible causes. This is a new FP4 I transferred to from my old FP4. I also upgraded to OTA-8 before transferring. And lastly, my new FP4 has an eSim configured on Android but it's inactive in UT.

humm, did you ever had battery-saver ?
If so maybe the service is still running if app data hasn't been cleaned ?
systemctl --user status batterysaver.service

@lduboeuf No, never used that.

@Martin5
This is by the way what happens when I encounter this issue. The Wifi icon has dots and stays like that.

@kugiigi I'm sorry for providing the wrong answer yesterday. It's the same like in your picture: Activating cellular data brings the dots in the Wifi icon.
@lduboeuf Never used that too and output of

systemctl --user status batterysaver.service

is

Unit batterysaver.service could not be found.

On the weekend I updated to OTA8 and the problem is as before. Does anyone has any good ideas?

Martin5

After reinstalling UT the problem persists. Shall I submit a bug?

@Martin5 Have you checked the APN settings if they correspond to the ones provided by the telecom operator ?

The default ones may not be accurate.
