I want to program my nfc tag to start forwarding calls, With task phone call and *21#1234567890#. This i can actieve, but i can’t use task phone call and #21#, to stop the call forwarding. Had anyone archieved to stop the dall forwarding with nfc tools?
Pretty sure those are two separate actions, is there a way to set it as a toggle?
You could use tasker Tasker - React To NFC Tag - YouTube it’s not as easy to use but I think you can make it do what you want.
Looked more at it and you can do it in nfc tools if you go to tasks and include conditional blocks
Thats exactly whattsapp i have
The mmi code (Ussd code) for call forwarding is working.
Only the stop code is not working. I get a message: connectionproblem or invalid mmi code.
I use *#21#. When i use this in the phone app. The callforwarding is stopped. So There it works.
So do hou have any ideas?
It might be that * is a special character that needs to be escaped somehow
Hmm, i think so too.
Now the question is how to escape this.
I get it working. I make a new contact with the #21#
Then i make a run a shortcut to this new contact,
Then it works.
