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 Studio 5.3 II D551A is a 2G GSM and 3G UMTS phone with no LTE and no VoLTE. US carriers retired 3G in 2022 and T-Mobile switched off the last US 2G GSM network on August 3, 2026, so it cannot register for calls or data on any US carrier in any lock state. Lock state is per listing; see the network status line in the table. It still runs as a Wi-Fi Android device and as a phone in export markets where UMTS service is live.
Resale fit
- Exporters supplying Latin America, Africa, and the Caribbean, where UMTS networks are still live and a boxed BLU Android sells on brand recognition.
- Wi-Fi-only deployments such as kiosks, point-of-sale companions, media players, and loaner devices.
- Prop houses and collectors who want a clean, boxed mid-2010s Android handset.
- Parts dealers and repair shops that need batteries, displays, and housings for BLU's Studio line.
