    Interesting thing happened yesterday.
    I had turned off cellular data for the past few days as I was almost over my data cap, and was near the end of my billing cycle.

    I had been limited to SMS to communicate those few days, but assumed it was working fine.
    Once the new billing cycle finally began I re-enabled cellular data.
    As soon as I did this, tons of SMSs I hadn't received while cellular data was disabled began flooding in!

    I always thought SMS was independent of the data connection?

    Just thought I'd post my experience as a heads up about the unexpected effects the setting can have. D=

    As far as I know, SMS is not affected by "Turning off cellular data." However, MMS is.

    But that is strange if you got a bunch of SMS messages after data had been re-enabled.

    +1 are you sure they were MMS that were coming in?

    Another confirmation that SMS does not use the data network but the voice network. Turning off the data network will have no impact on SMS messages.

    As others have suggest must have been MMS messages which does use the data network.

    Yes, two of them were MMS. That made sense to me.
    However, the other 10 or so were plain old SMS. All from different senders as well.
    Very strange.
