I'm going to be purchasing a cheap (under $100) Android tablet from an upcoming vacation and would like to have the ability to do basic web surfing when away from Wi-Fi hot spots. I can currently do the basic stuff on my cell phone but would like a larger screen. So, is it possible to attach a SIM card to a tablet via USB somehow? I will not be using 3G, just internet through phone towers, so I don't want to buy a $80 mobile broadband dongle, then pay an outrageous amount for service. Or, is it possible to link my cell phone and tablet via Bluetooth for web access? Thanks! BTW: I'm new here, so I hope this is the right place to post.
