T-Mobile Offers Square Mobile Payment Readers With Smartphone Upgrades

T-Mobile is unveiling a promotion with mobile payments company Square this week. Basically, T-Mobile is offering its business users an upgrade plan where they can get a 4G Pro smartphone, and an unlimited data, talk and text plan for $69.99 with a two-year contract extension.

But along with all of the above, T-Mobile is chipping in a free Square mobile payments credit card reader with a 4G smartphone upgrade. This appears to be the first promotion of Square by a carrier, which should provide nice publicity for the mobile payments startup.

Square first got a major promotion earlier this year when Apple began selling the mobile payments readers in its retail locations and e-commerce site. Now, Square is sold at 9,000 retail locations, which include Apple, Best Buy, Radio Shack, Target and Wal-Mart.

A few weeks ago, Square, which is processing $11 million in payments per day, launched its own marketing campaign to encourage existing users to give their favorite entrepreneur or small business owner a mobile payments device as a holiday gift.
