Sir, I have recently placed order for Samsung Galaxy tab 10.1. The seller says that it comes only with wi fi and no 3G sim. He says the one with 3G SIM not yet launched. But i could find GT 10.1 with 3G+ wi-fi in other online buying sites. If my devise has no 3G sIM slot is there any way to stay connected to NET on the go where there is no wi-fi spot.
