Philipp Humm, CEO of T-Mobile's US business, has circulated an email to the company's employees today encouraging them to stay upbeat through the Department of Justice's attempt to block the carrier's merger with AT&T. The focus seems to be on stemming customer churn and pulling new subscribers into the fold -- key metrics that T-Mobile USA has had trouble with over the last several quarters -- saying that "we will continue to prove there’s no better time to be a T-Mobile customer." AT&T's statement released earlier in the day certainly indicated that the company was totally blindsided by the DoJ's move -- and Humm echoes that, saying that both AT&T and Deutsche Telekom were "surprised by this sudden announcement" and vowing that the companies will fight it out with the government in court.

Follow the break for the full email.

Colleagues,

By now you have heard the news that the Department of Justice (DOJ) has filed a lawsuit to block the AT&T and T-Mobile merger in U.S. District Court. We were surprised by this sudden announcement, and DT will join AT&T in challenging the DOJ’s case in court.

DT and AT&T believe the DOJ has failed to acknowledge the significant consumer benefits of this deal. DT remains convinced that bringing together these two world-class businesses would create significant benefits for customers and the country.

While this action is addressed in Federal court, the best thing you can do is continue to focus on strengthening our business and offering world class customer service.

Customers have many reasons to choose T-Mobile—from the great value we offer, to compelling devices running on America’s largest 4G network and our leadership in customer service and satisfaction. Working as a team, we will continue to prove there’s no better time to be a T-Mobile customer.

Let’s build upon the positive momentum we’ve created in recent months. We have a great team here at T-Mobile, and I know you will join me in ensuring that, no matter what, ‘I Am T-Mobile Count on Me.’

I promise to make more information available to you in the coming days and weeks on OneVoice and through your leaders as this news develops.

Thank you for your ongoing commitment and support.

Regards,
Philipp Humm
CEO & President
T-Mobile USA
