T-Mobile is expected to announce a new phone plan/club today called “Jump” that will allow customers to upgrade to the latest smartphones when they like, at a “new customer” price.

Details remain sketchy, but The Verge and TMONews report the new plan will continue T-Mobile’s efforts to break free from the traditional 24-month upgrade cycle for phones offered by other carriers.

Although new by North American standards, providing an “equipment plan” is not unprecedented in Europe. O2 offers a “Refresh” plan specifically targeting likely early upgraders who want the latest devices and do not want to wait through a two-year upgrade cycle.

In North America, customers buy the phone at a subsidized price and then pay back that discount subsidy over the life of the traditional two-year contract (through artificially higher cell phone plan rates).

When one buys a phone on the O2 Refresh plan in Europe, the customer signs up for a 24-month equipment plan which covers both the cost of the phone, the Refresh feature and an airtime plan which covers everything else.

Customers who want to upgrade early simply pay off the remaining balance on their equipment plan (at a rate lower than the usual penalty fee) and upgrade the device at a discounted, new customer price.

T-Mobile has done away with the two-year contract most North Americans are familiar with, so the Jump plan will be different from O2’s Refresh Plan.

The Verge suggests T-Mobile will introduce a type of lease-to-own financing with Jump.

Customers will presumably pay a monthly fee to join the Jump “club” offering early upgrades. When a customer wants a newer phone, they might pay the same upfront fee a new customer would, but instead of being forced to pay off the full remaining balance due on their old phone, they would return it to T-Mobile and start a new financing arrangement for their next phone. If a customer keeps the phone until it is paid off, the customer would presumably own it.

CNET reports customers will also be provided with handset insurance, important if T-Mobile intends to keep an ownership interest in the phone until it is returned or paid off.

The details are forthcoming, but such a “lease-to-own” arrangement would still leave plenty of room for T-Mobile to recoup their costs, depending on how much they charge for the “upgrade anytime” feature.

The downside is that some customers may decide it is easier to pay off the remaining owed balance on a traditional T-Mobile financing contract and sell the phone to a third-party instead of sending it back to T-Mobile.
