Our family has decided to add an extra phone line to our international students. I went to see our carrier and I added it without problem, so I was a bit confused when my sister came down and told me that she had a problem with her phone. My sister has an iPhone, but the language exchange student and I have an Android phone. I was able to conduct an SMS conversation with the foreign exchange student, very well. My sister was able to receive text messages from the student's Android phone in exchange for currency, but when she responded, the message was sent to another iPhone user who previously owned the phone number. this student's phone. We know it because another girl answered. I called Apple to solve the problem and they gave the student in currency exchange a link to remove her iMessage number. This seems to have solved the problem for us.
I'm afraid it does not really solve the problem. And if two people had met in a bar, one with a newly connected Android, the other with an iPhone, and the first thing exchanged was nude photos? What happens if one of them has just received a new number that remains connected to an iMessage account? The Android user would have his picture sent to the right person, but the iPhone user would have his picture sent to the person with the previous phone number of the Android user (this is This is how iMessage works). And what happens if an iPhone user receives text messages to the point of changing their phone number and not updating their iMessage account? The spammer can register a phone on this number and use it to intercept text messages sent to him by other iPhone users. This is obviously a security issue with iMessage, but would it be considered a security exploit?
