I've got a 3G dongle and would like to use it with my Android tablet. Is that possible?
If the tablet has a USB socket into which the 3G dongle can be plugged and the appropriate driver software for the Android OS you should be all set. If not it could be tricky to achieve this with the dongle. However there is an app available via the Google Play store called PPP widget which is a no cost app. Results are apparently mixed so without testing this with the specific tablet and dongle it's difficult to predict how it'll pan out.
