T-Mobile Unlimited Plans Will Boost Keeping Customers?

By Lynn Walford 03/03/2009

T-Mobile has launched an unlimited plan for customers who have been with T-Mobile for at least 22 months without adding a contract commitment.

The plan includes unlimited calling for $50 a month, taxes are not included. These select customer can add up to four numbers to the plan for $40 each, (taxes not included. Unlimited data is $25 a month while unlimited BlackBerry data is $35 a month, or unlimited messaging for $10 a month.

This could keep customers from leaving for Boost. Early this year, Boost Mobiles Matt Carter said that the Boost unlimited voice/data plan was getting subscribers away from T-Mobile.

T-Mobile is also offering a $135 credit for referring new subscribers.
