It's pretty safe to assume that your cellphone bill is bigger than you'd like it to be. With the help of a new service provider called GIV Mobile, you can slice a little chunk off every month, but it'll go to charity instead of your pocket.

GIV Mobile is a MVNO operating on T-Mobile's 4G network, and offers a pair of non-contract plans: $40 unlimited everything with 250MB of data at 4G speeds, or $50 unlimited everything with 2 GB of data at 4G speeds. That's a pretty standard offering as far as non-contracts go, but GIV Mobile lets you pick up to three charities on a pre-approved list, and each month they'll donate 8 percent of your bill to your picks every month, automatically (up to $50 a year). The charity list includes heavyweights like the American Red Cross, St. Jude's Children's Hospital, and the American Cancer Society, with more on the way.

Charitable urges aside, GIV seems like a decent deal on its own; its plans are actually $10 cheaper than the T-Mobile counterparts (with slightly less data). You can send off for a free GIV Mobile SIM—which will work with any GSM phone—starting today. When it comes to features you can pick up with your plan, being a halfway decent person is a pretty unique one. What's that? You're going to just do that on your own? Suuuure. Yeah. OK. [GIV Mobile]
