I have a quick question about using iMessage with an iPhone user that has a cell phone registered in a different country I understand that in order to call a number outside the US, I need to dial 011+country code +city code and phone number. This is the same case to initiate a text message. Would this also be the same case to initiate an iMessage, or FaceTime Audio/Video Call? I am not talking about using iCloud e-mail address and using that e-mail address but the actual cell phone number? Since all the iPhones register a cell phone number automatically with the Apple servers how does Apple know how to route the iMessage or FaceTime between iPhones that reside in different countries? I appreciate any info.
