Hello community.
I wanted to make an app with app inventor which can send messages using the SIM card installed on the device. Like the messages app installed on Samsung phones, or Facebook messenger.
Is there a way or an ext (
) to do this?
What have you tried yourself?
Yes it is possible.

Well, I have tried messeging with cloud DB which worked perfectly, but I didn't now how to use the SIM card?
Thanks, but how?
Oops, and I forgot to say: the texting module of app inventor, opens the default messaging app in the system, and it can't send a message without opening that app.
I don't want that to happen, if there is another way, please tell it, else, I could continue with the texting module. 
That is a security change by Google. If your App is not going to be distributed via Google Play Store, then you can use text direct instead, but it's probably only a matter of time before Google makes the change a permanent part of Android itself.
Under Googles new measures, It would seem Apps only have read-write access to their own ASD (App Specific Directory) so no SIM Card access if using Android 10+.
So if you want to make a Chat App rather than a Texting App, then yes CloudDb is one way to achieve that.
