T-Mobile and the National Park Foundation (NPF) announced the first-ever Do Not Disturb Season, a nationwide invitation to silence everyday distractions and spend more time connecting IRL among the splendor of America's national parks — without missing the moments that matter most. Powered by the nation's largest and fastest 5G network and enhanced by T-Satellite with Starlink connectivity, T-Mobile's network gives customers the peace of mind to turn on Do Not Disturb and explore on their own terms.

To bring the spirit of Do Not Disturb Season to life, T-Mobile is giving anyone, even non-T-Mobile customers, the chance to experience the ultimate national parks Adventure On Us. Beginning today, through May 8, outdoor lovers can enter online or in participating retail stores nationwide for a chance to win.

And because protecting these natural and cultural landscapes is just as important as exploring them, T-Mobile is committing up to $1M to support the National Park Foundation. As the nonprofit of the National Park Service, NPF works to preserve America's national parks for present and future generations.

"Our customers take their phones virtually everywhere — including some of the most remote places in the country," said Mike Katz, President of Marketing, Strategy and Products, T-Mobile. "Connecting people in those places is exactly what we've built our network to do. Do Not Disturb Season encourages people to step away from the everyday noise and spend more time outside, knowing their network is built for the places they want to go — from the trailhead to the summit."

Bringing the Parks to Grand Central Terminal

More than 320 million people visit America's national parks each year, drawn to wide-open landscapes that offer a break from the noise of everyday life. To bring that spirit to the heart of New York City, T-Mobile and the National Park Foundation are launching the first-ever Magenta Base Camp at Grand Central Terminal.

From April 14–18, travelers can step into park-inspired landscapes in the middle of Manhattan — swapping marble floors for the trailhead. Magenta Base Camp will feature immersive installations that capture the sights and sounds of these iconic destinations, offering a brief escape from the rush of the city and reflecting how T-Mobile empowers people to wander freely on their terms. Between April 14-18, visitors to Magenta Base Camp will also be able to enter for a chance to win the Adventure On Us sweepstakes.

Whether mapping a last-minute route on AllTrails with coverage that extends beyond traditional cell towers, checking the weather before heading out or video calling family from the summit, the experience brings to life how T-Mobile's 5G network and satellite connectivity support the moments that matter — even in remote places.

"America's national parks offer an inspiration that no screen can replicate," said Chad Jones, SVP of Corporate Partnerships, National Park Foundation. "With T-Mobile's support, we're not just helping more people reach these parks — we're encouraging them to truly be present once they arrive so they feel inspired to also protect these cherished places."

Magenta Base Camp is open to the public on Tuesday, April 14 from 3-7 p.m. ET and from Wednesday, April 15 to Saturday, April 18 from 10 am – 4 p.m. ET
