is it possible to somehow have SIM tools app to switch roaming?
-
Hi,
my network operator require to switch roaming manually and my Ubuntu Touch does not have such app (like it is in Android) that can allow me to switch it.
Only thing I am left of when crossing the border is pull SIM card out, put it in some Android device, switch roaming, pull the SIM card out again and put it back to my phone.
Any advice what can be done is appreciated.

Hi @readyblue
In the drop down menu, you can select "Cellular settings..."
The second swith is "Data Roaming"Is it what you were looking for?
After crossing a border I noticed recently that I need to reboot the phone because switching to flight mode and back is not working for me. -
@AppLee nope. I know about Data Roaming, but that does not work. I have to manually switch roaming on my provider, so my SIM will be allowed to connect.
If I do not switch roaming on my provider, which is only possible by "SIM tools" app, my phone just say "denied" as network and there is no way to do anything with network at all. I have tried everything, believe me.
Android does have this "SIM tools" app which will show once you are connected to network which allows you to switch to:
- roaming abroad
- without roaming
-
That's weird.
But if this is an android app made for your provider then I guess you can try with Waydroid.I don't understand what this "manual switch" is about that would be different from the roaming switch we have in the settings.
-
@AppLee no, this is common Android app that is not for any particular provider. It is for general use
Also tried Waydroid, the app does not show up there unfortunately.

I'm sorry @readyblue
But it sounds to be an issue related to your specific provider.
People in your area might help on that, maybe you can join a local group on Telegram and see if others have the same issue and if they found a workaround. -
@AppLee yes, you are right, however on every Android this is possible via "SIM Tool" app, so I wander if something like that is planed for Ubuntu Touch?
Perhaps porting "SIM Tools" app?
-
@readyblue I don't think a SIM tools app is in the works unless we go and make one or commission one.. and coders aren't cheap. The OS is community run and these things only happen if somebody makes them happen.
Just to check, have you tried Mobile Settings -> Carrier & APN -> Carrier? From there I can select Automatic, or manually choose a carrier.
I do find that roaming can sometimes work strangely. Often I switch into roaming automatically once there's no signal for my carrier, but then it doesn't switch back when I'm back in a zone that my carrier covers. Sometimes there are glitches whereI seem to lose coverage in a zone that I know has coverage.
But adjusting settings or restarting usually works for me. -
I can't help to do this on UT, but I can explain what you are looking for.
Sometime there is two operators in a SIM card : your local operator and a roaming sponsor.
As example in europe, roaming sponsor is often Orange or BICS (Belgacom).So if you are in another country, the SIM card must act like it is from the roaming sponsor.
It can detect and switch context automatically, or you need to switch manually.
To switch manually, you have to run a "javacard applet" on the SIM card, to do that phones have a menu like "SIM-Toolkit-App". -
@ywilien Thanks for the helpful info. Who knows, maybe a thread like this spurs somebody to create something like that. It does sound like a pain in the neck the way that @readyblue has to do it. Hopefully something easier materializes.

Hello.
If this application is indeed an apk for Android, have you tried extracting it (via apkextractor for example) from the Android phone, transferring the apk to the UBT phone and installing it in waydroid?
I've recovered a few apks from my old phone this way. Some work, some don't.
