Samsung Galaxy M40 64 GB Midnight Blue, Factory Refurbished, GSM unlocked
Factory refurbished Samsung Galaxy M40 in Midnight Blue, 64 GB, 4G LTE, GSM unlocked, reconditioned to close-to-new working order. For a price-led exporter to South Asia this is the volume tier: a Snapdragon 675 Samsung with a 32 MP triple camera and 4K video at a cost well under new stock, in the color that sells best for this model.
The Galaxy M40, model SM-M405F, was Samsung's mid-2019 M-series flagship: a 6.3-inch Full HD+ PLS Infinity-O display with Screen Sound in place of an earpiece, a Snapdragon 675 octa-core chip with 4 GB of RAM and 64 GB of storage, a microSD slot in the shared SIM tray, a 32 MP, 8 MP ultra-wide, and 5 MP depth triple camera, a 16 MP front camera, a 3,500 mAh battery with 15 W USB-C charging, a rear fingerprint reader, and Android 9 Pie with One UI.
TG Wireless lists the Midnight Blue M40 new, factory refurbished, and as A Grade carrier-return stock for exporters and overseas resellers who want a Snapdragon 675 Samsung at three price tiers.

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 M40 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 1/3/5/8/40/41 are the Indian and South Asian set; it lacks US bands 2, 4, 12, 17, and 66. Treat it strictly as an export handset for markets using those bands. 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 and other markets on LTE bands 1/3/5/8/40/41, where the M40 is a known model with Snapdragon 675 performance.
- Overseas marketplace and refurb sellers who want new, A Grade, and refurbished tiers of one model.
- Parts and refurbishment supply for repair shops servicing the M40 in its home markets.
