What to know before buying

Listing details to confirm

The listing's Wi-Fi details conflict: it gives 802.11ac alongside Wi-Fi 4 and Single-Band operation at 2.4 GHz. The 50 Megabits Per Second upstream rate is also listed separately from the claimed 150 mbps download and Wi-Fi speeds, so treat these as distinct claims and confirm the intended figures before buying. The claimed 10-hour battery life is not a guarantee of use time. The listing excludes use in the USA and Japan. Compatibility with most countries and regions is a claim, not confirmation that a particular SIM or network will work.
