Samsung Galaxy M21 64 GB Midnight Blue, A Grade, GSM unlocked
A Grade Midnight Blue Samsung Galaxy M21, 64 GB, 4G LTE, GSM unlocked, listed as A-stock: lightly used, fully tested units sourced through carrier-return channels, with at most very minor marks. Marketplace sellers and overseas refurb dealers take this tier for buyers who want the M21's 6,000 mAh battery and AMOLED screen at a used price with consistent cosmetics.
The Galaxy M21, model SM-M215F, is Samsung's 2020 mid-budget phone built around a 6,000 mAh battery: a 6.4-inch Full HD+ Super AMOLED Infinity-U display, an Exynos 9611 octa-core chip with 4 GB of RAM and 64 GB of UFS 2.1 storage, a dedicated microSD slot, a 48 MP, 8 MP ultra-wide, and 5 MP depth triple rear camera, a 20 MP front camera, a rear fingerprint reader, USB-C, and Android 10 with One UI 2.
TG Wireless carries the Midnight Blue M21 in three conditions, new, A Grade from carrier-return channels, and factory refurbished, for exporters and overseas dealers who want an AMOLED Samsung with a two-day battery at each price tier.

Condition: A Grade
A Grade (A-Stock) units are lightly used, fully tested, and working, and may show very minor nicks or scratches. Units are supplied as graded; ask your account manager about packaging (original box, accessories, or handset only) when you request a quote.
Network and compatibility
The M21 is a 4G LTE phone, so the 2022 US 3G retirement and the August 2026 T-Mobile 2G retirement do not affect it, but its listed LTE bands 1/3/5/7/8/20/38/40/41 are the South Asian, European, and Latin American set; US bands 2, 4, 12, 17, and 66 are absent, so it is an export handset rather than a US activation phone. Lock state is per listing; see the network status line in the table. Confirm band fit and VoLTE acceptance with the destination carrier before ordering volume.
Resale fit
- Export lots for South Asia, Africa, the Middle East, and Latin America where the M21's battery and AMOLED screen make it the mid-budget volume seller.
- Overseas prepaid and marketplace sellers who stock new, A Grade, and refurbished tiers of one model at three price points.
- Fleet buyers abroad who want a 6,000 mAh Android 10 phone with USB-C for long shifts.
