It's sad that I will never really know about it. Because for some reason they never made Voice compatible with it. I only have 2 people I really text at all, and I use my voice number for everything, not my carrier number. I use the carrier number only for things that won't accept what they say it's a voip number. Even though that shouldn't have anything at all to do with their end of sending a message. I don't understand why they even check for that. It's not much of a problem, almost everything uses an app of some kind, I basically only get to see the actual texting app when the pharmacy says my medicine is ready to pick up. Voice number seems to work for pretty much everything else. (and by Voice number, I'm referring to Google Voice if you're unfamiliar)
