Hello to all,
As part of the development of an application, I would like to link my user's account to a cell phone in order to ensure that the user uses only one cell phone, is this possible and how to do it?
I would also like to make sure that this phone is used. To do this, I thought of checking that a SIM card is connected to the phone in question, is this possible and how can I do it? Do you have any other ideas?
Thank you for your help.
