On my Fairphone 4 with Ubuntu Touch 20.04 OTA-7 and a german amiva (Vodafone) SIM mobile data doesn't work.
It's a used phone and I think I tested the mobile data with Android.
At one time with this Ubuntu installation mobile data worked. But after a power cycle mobile data is gone again.
I tried another SIM card from congstar (Telekom) and mobile data doesn't work either.
Both SIM cards work on other phones with Android.
Airplane mode on and off, Data roaming on and off doesn't have any effect.
I tried serveral ofono commandos and I think here is the problem:
activate-context
gives this Error message:
Error activating /ril_0/context1: org.ofono.Error.NotAttached: GPRS is not attached
I attached the output of
list_modems
Could anyone help?
