I've had this issue since 3.1.2, everytime (and I mean every single time!) I open my SMS's I get the message

Could not activate cellular data network

You are not subscribed to a cellular data service

Now from what I know this is basically telling me I do not have any settings to connect to my telecom data service, but why is my phone trying to connect to the net when I'm looking at my SMS's? (The SMS's are there and there is no issue with them themselves)

I don't have a data plan and don't want my bill going up because my phone wants to go off connecting to the net just cause i'm reading SMS's!!

Am I missing something here? Is there a fix?

Thanks :)
 
You probably need to call your cell provider. It sounds like a problem from their end, unless something else isn't working right. If they can't help you, maybe get a sim replacement or restore in DFU mode.
 
Reset Settings on your iPhone...

So, I just started encountering the same phenomenon and when I saw what you guys were suggesting... well, anyway... I just went in under Settings > General > Reset > Reset All Settings. I tried just resetting the Network Settings first, but it did not change things. The unfortunate bit about all this is that you'll have to go and tweak your phone settings to the way you like them again as it will default all your ringtones/sms tones, erase your WiFi passwords, remove any themes you may have running through Winterboard, etc. It's a drastic step, but it worked for me.
