Anyone noticed that for other people who still have iPhone's that their texts go to the iPhone and not the Lumia 920 at all? My lumia 920 was activated yesterday 11/20 but even after that, in two cases I have friends who still have iPhones and when they text me, it comes to my iPhone 4 even though this sim card is no longer active in my iPhone 4. Is there a way to prevent that from happening? I'd like to not have to carry around both ALL the time to make sure I get text messages from friends with iPhones
