Hey everyone. I have this bug that already plaged several iphone users. I m gonna post my specific problem and I hope someone can share some insight. Screenshot bellow. 2 Questions: Lets begin, so 3 of the main Carriers in my country are "Vivo", "Tim" and "Claro" I bought 2 unlocked iphones. On the 1st, I put a "Vivo" chip. On the 2nd I put a "Tim" chip. On Vivo, iMessage activated. On Tim, it keeps forever waiting for activation. Afterewards, I took out the Tim chip and put a Claro chip on the 2nd iPhone. iMessage activates. Then, I got a second Tim chip and placed on the 1st iPhone. iMessage keeps forever waiting for activation. So, I am curious why the carrier Tim is not working properly with iPhones. There maybe some similar case worlwide, or even someone in this forum familiar with this particular carrier, so I tought this was worth posting. 1) Why does this happen? Now the second question wich is the most important. As I changed carriers (from Vivo to Tim, and numbers in the process) iMessage is not activating, at least not getting the new number. When I got to "send and receive" it shows my old number greyed out and not "checked" (old number is cancelled and SIM in the trash) Cause I do have an apple ID, I can log in into imessage using my icloud email, and therefore I have iMessage functionally working. My iPad and phone are gettint the same messages, everything looks good, even tough we know it isnt. 2) So, regarding security, do I need to worry? Eventually, my old number will go to someone else. When this happens, will this someone get my iMessages? When someone messages this old number, will I receive the messages instead?
