At the risk of sounding like the old guy crabbing about how easy the younger generation has it, do you remember when there were no mobile phones? When you left the house or the office, you were just basically unreachable. If you needed to call someone, you had to find a pay phone and hope you had change, maybe if it was a real emergency you would call collect. You paid per call, and if long distance was involved it was on the order of dollars. For ONE call.
Texting, mobile apps, the ability to call anyone from pretty much anywhere all unlimited, with the phone itself amortized into the monthly bill, for what? $30 a month? $40, $50? A BARGAIN.
And it's not like this fee isn't easy enough to avoid. Sign up for the recurring plan, or pay with an ACH, or send in a paper check if you think YOUR time to deal with a paper bill, write a check, find a stamp, address an envelope, and trek out to the mailbox is worth less than $2.
