When I respond to a text that was sent with multiple recipients, my phone converts my text to a multimedia message. I asked Samsung about this and they said the carriers automatically convert messages over a certain number of characters to multimedia. This has happened to me with short messages. The Samsung rep couldn't tell me the character limit for Verizon. I'm not sure her answer makes sense in light of the fact that it happens with short messages, and only messages with multiple recipients. Does anybody have any experience with this?
