T-Mobile customers wanting to upgrade their phones through Customer Care will have to pony up for the cost up front. Beginning July 1, 2010 customers will no longer be able to bill the upgrade charges to their T-Mobile account. Instead, they will have to use a credit or debit card to cover the costs.

EIP (Equipment Installment Plan) Customers will be required to pay the first installment only in addition to any upgrade and shipping fees. Government and business accounts are exempt from this policy change.

This will bring consistency to T-Mobile's purchase policies in place with FlexPay and Retail purchases. It is anticipated that this move will give T-Mobile a boost in revenue which may be applied to future promotions. Who knows, we may see another "free phone" weekend.
