Tell me if this is a bad decision: Paying $167.xx for 3 lines. (After 24% discount that applies only to some parts of the bill) Line 1: Unlimited Data Line 2: 3GB Datapro with $7.99 insurance Line 3: Dummy line I used for 2 year upgrade subsidizations If I switch to a mobile share plan with 25GB, it'll be $83.xx (24% discount) + $20 access charge x2 + $7.99 insurance x1. Naturally I'd drop the dummy line since it's worthless now. I'd be paying approximately $130 instead of $160. Is my calculation off anywhere? I'd gain tethering on my own phone with the same amount of data. After 22GB I'd get throttled anyways on unlimited or on mobile share.
