yesterday i took BSNL 2G Sim i want to switch to bsnl 3g for that i called bsnl customer care they said u will have to do a Rs.5/- recharge and then u will get a confirmation sms and then u will have to recharge by any 3g pack . (Eg:- Rs.400 for 1Gb)
Now i know that For using 3g we must untick the option "Use only 2g network" but all i want to know is when shall i untick that "Use only 2g network" option after getting settings for 3g or after recharging with desired amount of 3g pack???
