T-Mobile shutting down Sidekick service May 31

T-Mobile has announced that it will be shutting off the Danger Services for T-Mobile Sidekick phones on May 31 of this year. At that point, anyone still using a Sidekick phone will be left twisting in the breeze, although T-Mobile says it plans to roll out unspecified “offers” to existing SideKick customers in the next few weeks to get them to transition to a new device.

Without the Danger service, nearly all functions of the Sidekick phones will stop operating.

There may not be many T-Mobile Sidekick customers left: back in October 2009 the Danger services supporting Sidekick phones went down, leaving users without their data. Danger—a subsidiary of Microsoft—initially claimed that users’ data was almost certainly lost, and tried to place the blame at the foot of outsourced data center upgrades. Eventually, Microsoft announced nearly all user data was recovered and offered customers $100 gift certificates as compensation, but the incident was a serious blow to the Sidekick brand—Microsoft’s next step on the Danger line, the Microsoft Kin, fizzled almost as soon as it got out the door. The incident was also touted as an early example of the perils of cloud computing—although technically inaccurate, this week a number of Gmail users are certainly feeling the pain of having their precious data go missing “in the cloud.”

T-Mobile has launched a Web-based tool on myt-mobile.com that enables users to export their data—including contacts, photos, calendars, notes, and more—from the Danger service to a new device, an email account, or a computer. T-Mobile is also offering an app that enables users to export their Sidekick data to a memory card for quick transfer to a new device.

The first Sidekick devices were launched all the way back in 2002 and were among the first devices to enable mobile Internet connectivity—albeit via a GPRS connection. For a while, the devices were a fashion statement proudly touted by glitterati like Paris Hilton.

T-Mobile just set another 5G speed record

T-Mobile’s rivals may be nipping at its heels in the 5G race, but the Uncarrier is determined to stay ahead of the game. It not only boasts the fastest and most expansive 5G network in the U.S., but it’s actively working on technologies that will help it reach even greater peak speeds.

Two years ago, T-Mobile used a relatively new technique known as 5G Carrier Aggregation (5G CA) to achieve the kind of 3Gbps download speeds on midband frequencies that had previously been the exclusive domain of extremely high (and extremely short-range) mmWave technologies. Now, it’s chalked up another 5G first by taking advantage of the latest developments to shatter the traditional cap on upload speeds over sub-6GHz frequencies.

T-Mobile is a consistent leader in the ongoing 5G race, and to kick off 2024 on an interesting note, the carrier has announced that a big change is coming to its T-Mobile Tuesdays app. In short, the app is going away — and in its place, a new one is launching soon.

If you open the T-Mobile Tuesdays app today, January 2, you'll see a card that says "Introducing T Life." Below that is additional text that describes T Life as "a new app for T-Mobile Tuesdays."

T-Mobile still has the fastest 5G, but its rivals are catching up
T-Mobile smartphone.

For most of 2023, we’ve seen median 5G speeds among the big three carriers remain fairly stable, leading us to believe that things were beginning to reach a plateau. However, it now seems that this may only be true at the very top end of the 5G speed race.

Today, Ookla released its latest market research on 5G speeds for the third quarter of 2023, and it’s an interesting mix of surprising and not-so-surprising developments in the 5G market.
