A letter from T-Mobile to SunCom customers

December 18, 2007

As you may have heard, T-Mobile is in the process of purchasing SunCom to enable us to provide wireless services to the Carolinas sometime in 2008.

While we still need to get all the necessary approvals, we thought it would be important to answer some questions about T-Mobile for current and soon-to-be SunCom customers.

Let’s talk about T-Mobile’s planned approach to serving SunCom customers. Simply put, it’s our intention to provide comparable or greater value rate plans to SunCom customers. So whether you’re a SunCom customer today, or you’re thinking about signing up for SunCom service, T-Mobile looks forward to serving you and your existing rate plan, including the SunCom UnPlan.

T-Mobile, like SunCom, has a variety of plans that let customers make unlimited calls to the people who matter most to them. There’s a host of other benefits too. For one, we will be bringing SunCom customers complete access to a coast-to-coast national wireless network. On top of this, we’ve committed right out of the gate to making further improvements to the SunCom wireless network in the Carolinas. In addition, T-Mobile also has an outstanding customer service record. We’ve captured the top J.D. Power Award for Wireless Customer Care six times in a row. All this, combined with our cool lineup of phones and wireless devices, is great news for SunCom customers transitioning to T-Mobile.

We’re excited to be bringing T-Mobile service to the Carolinas. And once everything is wrapped up and we receive all the necessary approvals, we will be working around the clock to ensure that the transition for SunCom customers goes as smoothly as possible. Happily, as part of this transition, customers will not need to change their phone number or migrate to new phones or new technology to use their current service as our two companies already offer services on the same industry platforms.

No doubt there will be other questions that come up. But for now, rest assured we are doing all we can to put everything in place to bring T-Mobile’s stellar wireless services to the Carolinas as soon as we possibly can in 2008. We can’t wait to serve you!
