    Are you able to bring the phone in to your wireless provider's store and ask them to check it? That sounds defective.

    How long are you waiting after turning the mobile data back on again to see if it works? There can be a lag of several seconds before the mobile data connection is reestablished.

    Not sure how you were able to accidentally update the software. Did you try to install a system update that wasn't intended for your phone? That might have messed things up. In any case, you may just have to send the phone back to Samsung to see if they can fix it.

    There are a number of different versions of the S4, and each one may have somewhat different system updates, depending on the wireless provider. These updates are typically pushed to your device over the air (and, in the case of Samsung, also via Kies). When you said that Samsung told you that you shouldn't have updated, I was thinking that perhaps you might have downloaded an update from the web intended for a different version of the S4, and that's what may have caused the problems.

    My mobile data stays on or comes on automatically even when I turn it off. I wanted to use my phones camera on holiday recently but didn't want to pay the charge for using mobile data when I didn't want to use it anyway. I ended up having to buy a camera to capture memories.

    Is your phone unlocked? Do you have your APN settings in? This could be as simple as that.
