Dual SIM card - change "mobile data" provider based on location

[Janez Kranjski]

I use two SIM cards (different providers) in my OnePlus 5.
I can change which provider will be used for mobile data in "Sim & Networks -> Mobile data" and it works as it should.
But it is annoying to do this many times a day because each provider has its pros and cons locations
How can I automate this based on location? I spend some minutes in Tasker, but I didn't find mentioned setting.  

[joaomgcd]

Did you try using the Custom Setting action and try to find the setting automatically? Maybe that works. Thanks!

[Janez Kranjski]

Thank you. Your suggestion helped a lot :-) 

[João Dias]

So it worked? :) Great!

[Janez Kranjski]

I'm not sure yet. I prepared task and will see on my way home :-) 

[João Dias]

Ok. Hope it works! Some settings simply can't be changed this way, but if you're lucky it'll work!

[Janez Kranjski]

Report:

Both tasks (task itself and exit task) work in that way that they change what is written in "Sim & Networks -> Mobile data". So, it changes to expected/wanted provider. 
BUT - this only disconnects the active one but not connect to the wanted provider. As I said, the setting has a new provider selected, an old provider is disconnected, but there is no signal with a new provider.
Well signal is, but there is no 4G sign near signal indicator.

Any idea? Can I restart network or do something additional after changing settings?

[Janez Kranjski]

Can this be a "Custom Settings" feature bug?

I read about similar problems here on the forum. It looks like it changes the desired setting, but phone doesn't react to this (well at least in some cases).

[João Dias]

Yes, unfortunately not all settings will work this way. Sorry! Does it work if you reboot after changing the setting? 

[Janez Kranjski]

Tnx.
No, it doesn't work even after rebooting the phone.
Short conclusion:
1. Task (with Custom settings) changes selected mobile data provider - for example from SIM2 to SIM1 (I can see it).
2. Even if SIM1 is shown in a dialog, the phone still uses SIM2 provider for mobile data. But if I click with a finger to SIM1, then phone will change to SIM1 as it should.
3. After reboot, SIM2 is selected again (if this was changed from Tasker, otherwise it works as expected). 

BTW - Do you think that this will work next versions?

[João Dias]

No, sorry, some settings simply aren't prepared to be controlled from the background like this.. Maybe you can work around it using AutoInput? 

[Janez Kranjski]

I tried yesterday, but without success. 

As a newbie to AutoInput, I tried many times, but task simply didn't open the right menu. 
Is there any way to find Android IDs of the menu? I'm not sure which way is the best. In many attempts, I was not successful. Is maybe better working with screen position or some other idea?

[João Dias]

Usually what works best in Android menus is to simply use the text :) Did you try that?

[Janez Kranjski]

Yes, I did.

But in page "SIM & network" there are two same strings "Mobile data" and I want to change the second one and Tasker want to change the first one :-)

[João Dias]

Can you please show me a screenshot of that? Thanks!

[Janez Kranjski]

Of course ... Attachment.

[João Dias]

Did you try clicking on the text "Mobitel"? :)

[Janez Kranjski]

I tried many times, so I'm not sure. But yesterday I tried with a combination of "text" and "number in the menu" with AutoInput. I also noticed that wait 300-500 milliseconds between each action is very helpful.
Now it works, but only from time to time, to be honest. 
This morning I found "Accessibility service not running" (in attachment). I'm new to Tasker but I'm sure that I get this error before. When I check this in Android settings, it is enabled. Then I have to disable/enable it and it starts working. 

Any idea about this?

And not to forget - otherwise, I'm an experienced Android user but until now, I didn't use Tasker. So, I'm new to Tasker and I was really surprised how powerful this application is. I bought it and I'm sure that my friends will also be keen on it. 

[João Dias]

Do you think that AutoInput crashed before that error appeared? If not, something on your system is probably killing AutoInput in the background. Make sure the option for it to run in the foreground is selected in the main app and that no third-party app is killing it.

[Janez Kranjski]

I disabled Battery optimization for AutoInput. Maybe this will help. 
Tasker battery optimization was disabled before.

[Janez Kranjski]

Now I found something strange:
1. If I run Task manually, everything works fine.
2. If Task is triggered by profile, the task starts but then stops. 

I enable logging and maybe someone can comment this:

Can you please export your profile's description (not xml) so I can take a look? Long-click the profile in Tasker->export description Thanks in advance

[Janez Kranjski]

Yes. Here is it:

And there is also one more issue which is maybe connected with this - I'm often getting errors. Please see the attachment. 

Thank you for your great support.

Is the screen off when that happens? The screen must be on and unlocked for AutoInput to do its thing...

[Janez Kranjski]

Yes, the screen was off. 
My idea was that task is triggered when I come to my valley. And if I drive then the screen is normally off.

Should I add a task on beginning to switch the screen on? Is that possible?

[João Dias]

Yes, but only if your screen lock allows it. If you have to unlock it manually it won't work, sorry!

[Jimmy Jimmy]

Yes, when the profile triggers and if the screen is off, you can add a few actions to turn screen on, and enter the pin to unlock your phone with AutoInput. Then run your other SIM switching actions.

[Janez Kranjski]

I added a "Screen On" at the beginning of an action. My phone use fingerprint for unlocking the phone. 
It looks that profile is started but is waiting until I press on the fingerprint scanner. After that, action works.
This isn't perfect, but it is quite usable. It needs more test to be sure if everything is ok.

[João Dias]

Great :)

After some days, I can say that the solution isn't perfect :-(
So I'm looking forward.

Can Tasker get an information (to a variable) which SIM card (SIM1 or SIM2) is selected for data?

[João Dias]

Maybe try with the Custom Settings action?

[Jimmy Jimmy]

After a screen on action, you can use AI to unlock your phone using PIN. I believe even though you have fingerprint enabled, you always have a PIN. This will then work automatically.
