Description
Huawei Impulse 4G (U8800), Factory Refurbished, AT&T branded, unlocked
This Huawei Impulse 4G is the factory refurbished lot of the AT&T U8800, reconditioned to working order and GSM unlocked. A refurbished unit suits prop departments and collectors who need a functioning 2011 AT&T Android with its 3.8-inch screen rather than a parts phone. The -RB SKU suffix marks the refurbished grade.
The Huawei Impulse 4G (U8800) is a 2011 AT&T Android sold under the carrier's early 4G branding, which meant HSPA+ rather than LTE: a 3.8-inch WVGA touchscreen, Android 2.2 Froyo, a 5 MP camera with 720p video, Wi-Fi 802.11n with mobile hotspot, Bluetooth 2.1, GPS, a microSD slot with a 4 GB card included at launch, and a 1,500 mAh battery rated for about four hours of talk time. It weighs 4.41 oz and measures 4.7 x 2.5 x 0.46 inches.
TG Wireless offers the Impulse 4G as a tested 3G-era handset for collectors, prop houses, and parts buyers; it has no LTE and cannot be activated on a US carrier today.

Condition: Factory Refurbished
Factory refurbished units have been reconditioned to close-to-new working order. They are not brand new and may show light signs of handling. TG tests and grades each unit before it ships. Tell your account manager whether you need units with the original box and accessories or handset-only packs; the mix varies by lot.
Network and compatibility
The Impulse 4G U8800 is a 3G GSM/UMTS phone; its '4G' label referred to AT&T's HSPA+ network, and it has no LTE or VoLTE. AT&T shut down its 3G network in February 2022 and T-Mobile retired 2G GSM on August 3, 2026, so the handset cannot register for voice or data on any US carrier. Lock state is per listing; see the network status line in the table. Realistic uses are export to markets with live UMTS service, collectors, film and TV props, parts and display units, and Wi-Fi-only use.
Resale fit
- Export to markets where UMTS 850/1900 service is still live and an early Android sells at a low ticket.
- Collector and retro-tech shops that stock early AT&T Android phones.
- Film, TV, and theater prop departments that need a period-correct 2011 carrier handset.
- Parts and display units for repair shops and store fixtures.
