good day house and gurus, i have an app idea am currently trying to put in place, pls i want to know if its possible to have an app installed to mobile device and that app to be able to restrict that phone to only one user, my app would require a phone number during registration but i want where the user cant change the sim to register another account on same app and phone. thanks. hope i was able to pass the message properly.cheers

1 possible solution I can think of right now is, once the user is logged in with their phone number into the app, don't provide an option where they can log out.
Unless they uninstall and reinstall the app or clear app data.

Very possible, only if you make the app run in hidden process and know how to reverse Mobile Phone OS.

You can then write a function to accept only one sim, if the phone is stolen and somone else puts another sim, it should go blank. You have to only learn how to reverse the phone OS totally if you can learn assembly / Android reverse engineering, that sort of app would sell Billions.

I have been thinking of some app like that.

TOS phone number verification can do that by sending the codes as SMS. Provider like auth0and twillo has API for implementation.



or u can buy unlimited SMS create a php script to send pin automatically and connecting it using HTTP (retrofit or volley) to Android .

Thats another good one. But he can do something like a lockdown, so that no one uses the cell ... for security. If hes developing on Android, he can use Bluestacks as Emulator.

it is 100% possible u can use imei phone identity and store it in registration db and check db if user is attempting to register with another sim ave done dis using Json php mysql with android studio whatsapp me @ 08142528303
