Samsung Wave 578 3G Wi-Fi 3.15 Megapixel Touchscreen Bada OS, New, GSM unlocked (listed AT&T)
Brand new Samsung Wave 578 3G WI-FI handsets, the 3.15 Megapixel Touchscreen Bada OS phone listed as AT&T GSM Unlocked, boxed and SIM unlocked. Exporters who sell sealed low-cost 3G touchscreens with NFC in UMTS markets are the fit; US band compatibility is not claimed.
Samsung's Wave 578 GT-S5780 is a 2011 bada 1.1 touchscreen with a metallic body, notable as one of the first budget phones with NFC. It has a 3.15 MP camera with geotagging and QVGA video, a VGA front camera for video calls, 100 MB of memory with microSD to 16 GB, 3G HSDPA data, Wi-Fi 802.11 b/g/n with hotspot, Bluetooth 3.0, A-GPS, and a 1,200 mAh battery.
TG Wireless sells the Wave 578 new to exporters serving markets with live UMTS or GSM service, to collectors of the bada platform, and to prop and parts buyers. It has no LTE and does not activate on US carriers.

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 Wave 578 GT-S5780 is a GSM/UMTS phone with 3G data and no LTE or VoLTE. All three US national carriers retired 3G in 2022 and T-Mobile ended 2G GSM service on August 3, 2026, so it cannot register for calls or data on a US network today. Lock state is per listing; see the network status line in the table. Buyers move it into export markets where GSM or UMTS is still live, to collectors, prop houses, and parts dealers.
Resale fit
- Export lots for regions where GSM or UMTS service is still live and an NFC-capable touchscreen sells at a low ticket.
- Collectors of Samsung's bada platform and early NFC phones.
- Parts and display units for repair shops and store fixtures.
