Bellevue, Washington — April 1, 2018 — It's time for a comeback. T-Mobile (NASDAQ: TMUS) today announced it's bringing back its most beloved and iconic device — the Sidekick! And it's even better than you remember! ... Today, T-Mobile unveils the world's first Smartshoephone™: T-Mobile Sidekicks.

Why did Sidekicks get discontinued?

Microsoft bought Danger Inc. ... As the physical keyboard became less useful, the Sidekick brand went through its biggest change in 2010: T-Mobile announced that it was dropping Danger's data service. So, Danger turned off its servers, and older Sidekicks that relied on their data centers were rendered useless.

Can you still use a Sidekick in 2020?

If you wish, you can still use the Sidekick for calls and text messaging. T-Mobile will begin sending out letters to current Sidekick owners tomorrow to alert them to the change and provide information about transferring data and transitioning to a new device.
