Unable to use mobile data on Sony Xperia 10 III 4.4.0.64

4.5.0.19

Finland, Home

  • Elisa, Dual, Xperia 10 III: Data is available

Greece (Spili, Crete), Roaming

  • vodafone GR, Dual, Xperia 10 III: Data is available (but see below)
  • WIND GR / NOVA, Dual, Xperia III: No data (2,5G (edge), no data arrows)

After device connected this ‘NOVA’ then – in the first times, had to reboot the machine for vodafone connection to get data connection working (data arrows with 4G and 2,5G).

I unchecked Select network automatically to avoid changing from vodafone to nova, but it still did change sometimes (it could be that vodafone was not available at all or something)…

Then I went south to Plakias (that was yesterday), at mediterrian – there vodafone and 4G was consistently available. There, to know better, I “forced” nova from connections menu, and as expected,
data connection was lost – but I could not get it back after rebooting anymore (2.5G w/ vodafone and no data arrows)…

… Now I did the “trick #3”, i.e. disable ofono, rm …/ofono/* and reboot… and got vodafone 4G and data arrows back.

Great, I thought, problem soloved… but not so fast – when got back
to Spili, and in a place where vodafone signal was not strong enough (or so I think), phone connected to this ‘WIND GR’ – which
then converted to ‘NOVA’ and data connection lost. Now even reboot did not help, had to the trick #3 again.

Today I have done the trick #3 another 2 times. I am not sure if all of those were necessary. Last I did 1/2 hours ago – after that w/ vodafone I had 2,5G and no arrows – but I just got a message (phone in wifi), but noticed 4G (and after disabling wifi, data arrows)

I’ve tried everything I could imagine to get the data connection up without rebooting, sim2 on sim1 off sim1 on again – which may be quite same as toggling flight mode. I also tried sim2 slot but there was no difference. sailfish utilities network restart and systemctl ofono restart were tried, and so on…

I have quite a few screenshots taken from settings view and from CellMon screens, if these are of any help. I’ve also redirected dmesg outputs to files (10 of those in last few days).

I am soon heading back home (sunday), and there network just works for me. But while I am here I could try to collect more useful data if I’d know what to do…
