The Huawei B636-336 router supports 4G LTE with multiple bands compatible with many European carriers, including Iliad. It uses a Nano-SIM card and supports LTE bands B1, B3, B5, B7, B8, B20, B28, B32, B38, B40, B41, B42, and B43, which cover the 4G frequencies used by Iliad in Italy and France. Therefore, it is suitable for use with a 4G/5G Iliad SIM card, although it supports only 4G LTE and not 5G connectivity. The router offers stable 4G internet with Wi-Fi 6 and multiple Ethernet ports for wired connections.
