The samsung galaxy s3 was on sale today at bestbuy and i have an upgrade so i thought i would go buy one. right now i have t-mobile with a $29.99 voice plan (old voice plan) and a $4.99 texting plan. I was going to add a $20 data plan for my galaxy s3. So i get to bestbuy and he starts the setup, asks our address blah blah blah and then he says "oh.. the current plan you have wont work with the galaxy s3."............................... How does a voice plan not work with a phone? Out of every single friend or family member that has a smartphone, none of them had to change their plans. Even the ones who had their voice plans for over 15 years. Why do i need to change my voice plan? according to bestbuy id have to change my $55 plan(including data and texting) to a $70 plan. I don't want to pay $70 every month plus tax. I have a cheap plan for a reason.. Whats the point of upgrading a phone if they make you chose certain plans to use with that phone? If all this is true, then t-mobile is the biggest scam i've ever seen and im going to ****en AT@T. Any help is appreciated. thanks!
