Always the message, but less recursive, despite the updates

The problem remains present even in unstable.
The problem is mainly that it eats the battery

Can you post your carrier you have? Also, that message is related to mobile data, it is WIP at the moment and does not affect calls or sms/text. Most likely introduced due to our work with Canonical and KDE e.V.:

reinstall: before sav: calendori/vard phonebook
indeed when I turn off mobile-data I no longer have an alert.

stop mobile-data blocks the restart of the telephone link ;
On the other hand when you restart you have to do sudo systemctl restart ofonoctl

How to configure MMS .svp

Hello, the 2021/03/19 last update plasma-mobile.

I only have one message telling me a problem with the mode and it is only after a reboot, otherwise the recursive messages on disappeared.

That’s nice to know. :slight_smile:

Sounds like this is known and being handled, but wanted to put forward my experience as well anyway.

I’m also getting this notification. I’m not 100% sure what the cause is yet as it’s not all the time, but when it happens it tends to notify me every 5 minutes with the following:

Modem (quectelqmi_0)
The modem shows no carrier

I’m with Honest Mobile (UK), but I’m roaming and connecting to Proximus (Belgium) cell sites.

I’ve also noticed another issue in a similar area.
I get the following notification occasionally:

Modem (quectelqmi_0)
IP configuration was unavailable

When this occurs, I lose signal and must restart the phone again to get it back.

Just got the new pinephone beta edition. Was getting “modem shows no carrier” mobile data did not work. I could make phone calls okay.

sudo systemctl status ofonoctl
and it reports
inactive (dead)
Trying to online a modem that's not powered on

sudo systemctl restart ofonoctl

Get’s me a promising:

Brought quectelqmi_0 online

But still I get no data/internet connectivity.

Any ideas?
(I hope this helps somebody.)
