So hi. i'm thinking about getting 9300 becuase is newer than 8520. I just have a problem about the plan. when i click on it i said pick a plan 25,30,35+ data plan. But 8520 doesn't have the data plan. For 9300 do i have to pay extra 10dollars on the data? If i want go to like best buy and buy it. And i want BBM with it. Please help me.
