Following our post on high-speed cellular networks , we’re going to show you how to switch your internet connection settings to turn off 3G, turn internet off and turn roaming off.
How to turn off 3G Internet on the iPhone
If you still want to use the 3G network but turn off the internet, this is how you do it:
* Note that turning “Cellular data” off, you’re turning Roaming data off as a result.

How to turn 3G off (switch to 2G) on the iPhone
If you prefer to downgrade from a 3G network to a 2G network (maybe because of better coverage), this is how you do it.
*Note that some carriers might not have a 3G network. So by turning 3G off, you are basically shutting all communications down, as the phone is unable to switch to the carrier’s 2G network (as one doesn’t exist!).
“Settings” – > “General” – > “Network” – > “Enable 3G” – > Done, no 3G!

* Note that there is no indicator on the status bar to show that you have roaming off.
“Settings” – > “General” – > “Network” – > “Data Roaming” – > Done, no roaming!
