I am mobile but the whole grandfather in with unlimited data is a lie. Now when you upgrade or buy ANY new phone you have to switch to their unlimited plan. Which is $45 smart phones a month, $30 for regular phones, $10 for tablets. Which isn't bad....but wait if you want data....you have to pay $50 for 1 gb that all have to share 2 gb $60, 10 is $100. On average most people use about 3 gb.
Right now my plan is 700 with 250 text on two phones and pay per text on 3. I have one smart phone with unlimited and two regular phones and my bill pre taxes is $115. We never go over mind in fact we used about 250 combined (most people are in network) With the new plan with out data its $90 add in that my phone say I average 2 gb a month (I use lots of WiFi.) That is $150 before taxes.
I am pissed. And I have to stay with them until 11/24/2013
Edit to add: this takes affect June 28, 2012 NOT before, and it only affects you when you use your renewal discount OR add a device. You can keep your old plan IF you buy your phones retail ($400-800 for smart phones, $100-400 for regular phones)
