What Kind of World Do You Want? Another great and emotionally powerful performance last night by @johnondrasik /Five for Fighting. Thank you John!

[Mike Sievert @MikeSievert]

The secret behind @TMobile’s success is a team with relentless spirit. 💪

In my final episode of Sidekicks Conversations, I talked with @SriniGopalan about the We Won’t Stop ethos that powers us: customer love, empathy and drive. And with Srini, that spirit is in great hands!

[Mike Sievert @MikeSievert]

As @WSJ highlights, @SriniGopalan is ready to unleash the Un-carrier as our next CEO. He’s already driving the business forward in wireless, broadband and fiber - with so much more to come. There's no better leader for @TMobile’s next era.

T-Mobile US named Srini Gopalan, its chief operating officer and a veteran of parent company Deutsche Telekom, as its next chief executive officer https://t.co/iBe8xusl7d

@JohnLegere Thanks, John! Grateful for the foundation we built together. The company’s never been stronger, and I can’t wait to see where @SriniGopalan takes it!

[Mike Sievert @MikeSievert]

Today marks a milestone moment for @TMobile — and for me personally. I’m proud to share that @SriniGopalan, our COO, will succeed me as CEO, effective Nov. 1.

This transition comes at a time of extraordinary success and momentum for the Un-carrier. I've long said the best time to plan for what’s next is while you’re at the top — and without a doubt, Srini is the right leader to guide T-Mobile into a new era of growth, innovation and customer obsession.

I'll continue as vice chairman of the company and board, championing our leadership team and supporting our mission to be the best in the world at connecting customers to their world.

I’m incredibly optimistic about what’s ahead for our customers, our employees and our shareholders. It’s been the honor of a lifetime to lead Team Magenta. And the best is truly yet to come.

Please join me in congratulating Srini!

The Olympic & Paralympic Games are a chance to show the world what leadership looks like. For athletes, absolutely. And in 2028, for @TMobileBusiness, too.

Proud to be the Official Telecommunications Services Provider for the #LA28 Olympic & Paralympic Games!

It’s official: @TMobile and @UScellular have joined forces!

We’re welcoming UScellular customers to America’s best network with unbeatable value, a best-in-class experience, and more choice. This is a gamechanger, especially for consumers in smaller markets and rural areas.

And we're adding 3,000 new towers so T-Mobile customers will benefit from enhanced coverage and added capacity, too!

There's never been a better time to be part of the Un-carrier! https://t.co/Gm78Tew1NG

Today marks a huge step in @TMobile’s mission to end dead zones. T-Satellite is officially out of beta and available to anyone who wants it — including Verizon and AT&T customers!

With 650+ satellites in orbit, the largest satellite-to-mobile constellation on the planet aims to connect you almost anywhere you can see the sky. It's already helping save lives during disasters and providing an extra level of safety for those who love to explore the great outdoors.

And we’re just getting started! #WeWontStop

The @Starlink team and @TMobile have also enabled basic texting (SMS) through our Direct to Cell satellites for TMo customers in the areas impacted by flooding in Texas. This includes Kerr County, Kendall County, Llano County, Travis County and Comal County.

Additionally, anyone in the impacted areas with a compatible smartphone will be able to receive emergency alerts from public safety authorities.

[Mike Sievert @MikeSievert]

My heart is with everyone in Texas as this terrible flooding impacts so many.

@TMobile’s network is holding strong. We’re providing supplemental coverage to support first responders, have community support vehicles ready to help as soon as it’s safe, and we’re in touch with government agencies.

Please stay safe, everyone.

[Mike Sievert @MikeSievert]

12 years ago, we were dead last.

Today, @TMobile has the BEST Network in America — confirmed by Ookla in the biggest network test ever in the U.S.

This isn’t just a big claim. It proves a different approach works: Build with customers at the center. Bet big. Stay relentless.

That’s the Un-carrier way. And we’re just getting started! #WeWontStop

@Techlife32 Appreciate the concern, but there was no hack. The data doesn’t relate to T-Mobile or our customers.

[Mike Sievert @MikeSievert]

@ChevyJ_ @TMobile @JonFreier Congrats on your degree! 👏🎓 So proud we could back you on this journey.

[Mike Sievert @MikeSievert]

@LuzRodTMO You said it... THE BEST OF THE BEST! 🎉 Congrats again!

I grew up Catholic, and while I am not personally close to the church as an adult, I have deeply admired Pope Francis, who led with humility, compassion, and humanity. Today I join millions around the world in mourning his passing. May he rest in peace.

[Mike Sievert @MikeSievert]

2024 was a landmark year for @TMobile. One that proved you don’t have to choose between growth and staying true to who you are.

Now, we’re using that momentum to transform how we serve customers in a digital-first world.

We just shared the highlights in our Annual Report. ⬇️
