Samsung Sidekick 4G Wi-Fi 1 GHz 3.5" Touchscreen QWERTY Android, New, T-Mobile / SimpleMobile
The Sidekick 4G WI-FI 1ghz 3.5" Touchscreen Qwerty T-Mobile / Simplemobile Android is a new, boxed Samsung Sidekick 4G in the standard finish, with a 3.5-inch touchscreen, five-row QWERTY keyboard, 1 GHz processor, Android 2.2, 3 MP camera, and Wi-Fi. A sealed Sidekick 4G is the unit nostalgia resellers and prop houses pay for, box and accessories included.
The Samsung Sidekick 4G is T-Mobile's 2011 Android reboot of the Sidekick, a 5.7 oz slider measuring 2.42 x 5.0 x 0.6 inches with a 3.5-inch WVGA touchscreen, a five-row QWERTY keyboard, a 1 GHz processor, Android 2.2, a 3 MP camera, Wi-Fi, and a physical jump key for switching apps. Sidekick Group Text and Cloud Text ran group messaging across phones and PCs, the Sidekick Media Room pulled together streaming video and music, and HSPA+ data on T-Mobile's Bands I and IV peaked at 21 Mbps, with quad-band GSM for roaming.
Collector shops, prop houses, and nostalgia resellers buy the Sidekick 4G from TG Wireless in new and refurbished grades, since its GSM/HSPA+ radios get no US service today.

Condition: New
Brand new units in the original box with the original in-box accessories as listed. Nothing has been activated or reconditioned. If your channel needs sealed retail packaging rather than open-box new, say so when you request a quote so the account manager can confirm how the lot is packed.
Network and compatibility
The Sidekick 4G is a GSM/HSPA+ phone whose "4G" means HSPA+ data on T-Mobile's Bands I and IV; it has no LTE radio and no VoLTE. US 3G retired in 2022 and T-Mobile shut down 2G GSM on August 3, 2026, so it gets no US voice or data service. These are T-Mobile / Simple Mobile branded units; see the network status line in the table. Realistic uses are collectors, film and TV props, Wi-Fi-only Android use, parts, and export to live UMTS 2100 markets if unlocked.
Resale fit
- Collector and nostalgia resellers who want new or clean refurbished Samsung Sidekick 4G sliders.
- Film, TV, and theater prop houses needing 2011-era T-Mobile Android phones.
- Parts dealers supplying five-row keyboards, screens, and housings.
