Problems with text messaging
Hi--
I am using my friend's old iPad (he's on Verizon and I'm on AT&T. I have permission to use his data) . Trouble occurs when I try to send messages to certain contacts. It switches from SMS (blue) to MMS (green) and fails. No BLOBs (pictures or images) just plain text. Why does it switch from SMS to MMS? How can I prevent it?
I took the latest update iOS 9.3.4. I am not tech savvy, simple answers please????
