Sign of things to come for other carriers?

Aside from the reality that not every cell phone user owns a computer, when you contract with a service provider their billing has already taken into account the cost of all aspects of billing. This would in effect amount to a double billing.

They are eager to pass off any expenses to them onto their customers, so, if T-Mobile realizes a savings in not printing bills, they should pass that savings off to their customers as well.

I'm sure they'd be happy to explain how you can use the web browser on your phone to access the bill online... and happy to sell you a fancier, web-capable phone and an upgraded data plan if you need it! *sigh*

Just call T-Mobile and tell them that you're instituting a $2.00 Processing fee for receiving electronic bills when you want paper bills.
