That happens regardless. The reason for it is this: SMS and MMS use true voice channels instead of data. EV-DO means "Evolution Data Only" or some say "Evolution Data Optimized". Either way, EV-DO only supports data. No voice, no SMS, and no MMS.
You'll notice the same thing when you're in a voice call, unless you have Rev. A EV-DO in your area, which I BELIEVE is theoretically capable of handling a data call AND voice call simultaneously.
