Asus ZenFone 3s MAX 32 GB Black 4G LTE, New, GSM unlocked
Black is the finish of this Asus ZenFone 3s MAX, a brand-new 32 GB handset, GSM unlocked for 4G LTE. The black 3s Max is the one fleet and field-service buyers pick, since it looks uniform across a deployment and the 5,000 mAh battery covers a long shift without a charger.
The ZenFone 3s Max, model ZC521TL, is the early-2017 refresh of Asus's battery-first budget phone. It packs a 5,000 mAh cell into a 5.2-inch 720p metal body, with a MediaTek MT6750 octa-core chipset, 3 GB of RAM, 32 GB of storage with microSD expansion, a 13 MP rear camera, and a fingerprint reader in the front home key, on Android 7.0 Nougat. Reverse charging through OTG lets it top up other devices. TG Wireless sells it new and GSM unlocked to dealers who need a cheap, long-running Android handset for export, field and delivery work, and prepaid-style counters where runtime is the selling point.

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 ZenFone 3s Max is a 4G LTE handset, so the 2022 US 3G shutdowns and T-Mobile's August 2026 2G retirement do not take it out of service by themselves, but LTE service still depends on the band set and VoLTE support of the exact regional variant. Lock state is per listing; see the network status line in the table. Before buying volume for US activations, confirm VoLTE acceptance with the carrier; for export, match the variant's LTE bands to your local networks.
Resale fit
- Export to markets where a dual-SIM, 5,000 mAh budget Android is a daily seller.
- Field-service, delivery, and institutional buyers who need all-day runtime from a cheap handset.
- Prepaid-style dealers and kiosks selling new unlocked phones at an entry price.
