I've read a lot of questions about this, and the answer that I saw is that its' not possible and there's a possibility that the app will be rejected.
One of the requirements that we have is to get the SIM card number of the device to serve as an identifier.
Is there a workaround to get the SIM card number? Also, if there's any, can we have the number encrypted for the app to avoid the rejection?
Thank you!
