I heard that I might be missing a band or something....anyone got some knowledge to drop on me?

Take a look at this link from Apple. Compare the bands for carriers. Band 30 is the one you're referring to. As of the 6S release last year, it was a relatively new band for ATT and not available in all of their coverage area. I don't know where they stand now.

Typically, Sprint devices will not work on AT&T's network, but I'm not sure if that has changed.

Gotta check the bands. If it's unlocked, it may work. I know for the 7 it will bc it's the same model as the Verizon one and I'm using a Verizon one on ATT.

Did you have any problems with MMS on AT&T using the Verizon version?
