Before iPhones and Androids dominated the market, there was a phone that ruled the world of texting, instant messaging, and mobile swag—the Motorola Sidekick. Though often associated with T-Mobile and the Danger OS, Motorola also had its imprint on this legendary device lineup, combining unique hardware with stylish form factors and unmatched messaging capability.
While the Sidekick name wasn’t exclusive to Motorola, its involvement helped cement the phone’s legacy as a game-changer for teens, celebrities, and business users during the early-to-mid 2000s.
What Was the Motorola Sidekick?
The Motorola Sidekick was a collaborative release with T-Mobile and Danger Inc. that featured Motorola’s take on the hugely popular swivel-screen smartphone. It stood out with its iconic flip-up display, revealing a full QWERTY keyboard underneath—revolutionary for the time when T9 texting was still the norm.
Motorola developed specific models like the Sidekick Slide, which replaced the traditional swivel hinge with a compact slide-up screen, adding a sleeker, more pocket-friendly form factor.
Key Features of the Motorola Sidekick
Slide-Up Display
Unlike earlier Sidekicks with a swiveling screen, the Motorola Sidekick Slide offered a smooth vertical sliding display, giving the phone a more modern and compact look while retaining full access to the keyboard.
Full QWERTY Keyboard
Texting and emailing were never easier. With raised tactile keys, users could type quickly and accurately, making it a dream device for social butterflies and professionals alike.
Instant Messaging & Email
One of the Sidekick’s biggest selling points was its support for AIM, Yahoo Messenger, and MSN Messenger, along with real-time email push—a rarity for consumer phones of the era.
Customizable Interface
Using the Danger OS, the phone offered a cartoon-style interface, theme customization, and dedicated apps for social media, messaging, and more.
Camera and Media
The Motorola Sidekick Slide came with a 1.3MP camera, MP3 playback, and support for microSD cards—allowing users to enjoy music, take photos, and store media on the go.

What Happened to the Sidekick Line?
