Hey guys, if I have Cellular Data turned off, is it pertinent to have Enable 3G on? does it actually changes something? It seems that I have a bit more signal when Enable 3G is on, even if Cellular data is off...

Thanks!

    When accessing the internet via your carrier's 3G network, your internet connection will be faster and more battery will be used when doing so.

    If you don't need or want a faster internet connection when connected to your carrier's cellular network, you can turn 3G network access off which you aren't using for internet access via your carrier's network when Cellular Data is turned off. When cellular data is turned off, you can't access the internet via your carrier's network via your carrier's 3G, EDGE, or GPRS network, whichever is available at the time.

    You will place and receive calls and exchange SMS/MMS via your carrier's 3G network when Cellular Data is turned off if 3G network access is available at the time, and if 3G network access is turned off in addition to having Cellular Data turned off, you will place and receive calls and exchange SMS/MMS via your carrier's EDGE or GPRS network whichever is available at the time.

    But if 3g is enabled, and cellular data is off, I won't get billed any data fees, correct?

    As already provided, if Cellular Data is turned off, you can't access the internet via your carrier's cellular network so it will be impossible to have any data fees if you don't have access to the internet via your carrier's cellular network. You can place and receive calls and exchange SMS/MMS via your carrier's 3G network - SMS/MMS does not use data. SMS/MMS is exchanged via the same network as calls - SMS/MMS is not exchanged via your carrier's internet network. You can place and receive calls and exchange SMS/MMS via your carrier's 3G network if available at the time and if 3G access is not available at the time, calls and SMS/MMS will be exchanged via your carrier's EDGE or GPRS network. If you have 3G turned off, you will exchange calls and SMS/MMS via your carrier's EDGE or GPRS network.
