I have a DROID RAZR MAXX HD by Motorola and the pass several months if I get a text from an iPhone, I first get a text stating that it is downloading. It normally takes 3 minutes to 3 hours for it to download. Some times longer and several times it took over 24 hours. But at times the text is on the phone right away. When I stopped in at a Verizon store they said it was because the iPhone under setting did not have the send as SMS checked. All the ones that I could check that I receive texts from did have the setting checked correctly. Any ideas Dennis
