Why are the text messages from answering service coming in "Download"

[AC Question]

These messages are from a third party answering service.Why are the text messages from answering service coming in "Download". When i hit download the message still wont come through. They came through for a year and then we got a new phone. After a few months we started having this problem. Answering service says its carrirer. Carrier says its answering service and phone store says its the phone (so he can sell us a new phone). We tried a reset (not master).

Welcome to Android Central! The "Download" option usually means it's an MMS message. MMS requires mobile data to be on--is yours on?
