T-Mobile may be a distant fourth in the wireless carrier race, but it’s scrappy. Bouncing back after its proposed acquisition by AT&T crumbled, T-Mobile is aggressively courting small business customers with a variety of services.

For starters, T-Mobile is the first of the wireless providers to start offering the Square credit card reader in its stores. The reader can be acquired for free directly from Square, but T-Mobile is helping small business customers expand their payment options and get paid faster by giving customers even easier access to it.
