I understand the default tmobile plan and the pricing for it. Currently I have a 3 line uncarrier family plan with tmobilethay can be cancelled anytime. It would cost $10 monthly to add a new line to the plan which comes 500mb of 4g and ulimited 2g(?). $20 for 2.5gb. And $30 for unlimited.(which I currently have on my phone.) I understand it gives me a bit lower data for the price point unless I go for $30 unlimited. But would it be worth it to get the $20 plan with .2gb less but not have to worry about running out because after I use up 2.5gb I would just get slowed down and not have to pay again to use the 4g like the default plan. I hope I was being clear. Thanks in advance.
