What to know before buying

Listing details to confirm

Listing details are inconsistent about the antenna, describing it as fixed in the specifications but foldable in a highlight, and about power, with USB-C power support claimed while the box list names a power adapter. Confirm the exact hardware and included power arrangement for the selected listing. The listed 150 Mbps mobile and 300 Mbps Wi-Fi rates are stated maxima, not guaranteed speeds. Actual 4G performance depends on coverage, network and location.
