I can't answer that. The device works perfectly in the Salt and GoMo networks. Switchable to 2.4 and 5 GHz Unfortunately, the device does not have a rechargeable battery and must be permanently connected to the mains, making it less suitable for travelling.

The device does not have a battery and requires external power via USB Type-C. It can be powered through USB Type-C and also provide internet to a connected computer via USB Type-C tethering, enabling a wired connection instead of wireless. This USB tethering mode uses the USB 3.0 Type-C port for both power and data transmission to the computer.

The router must be connected to the power supply. Then insert the SIM card. If you have ordered a new SIM card, you must first activate it (or have it activated).

Hello, it says on the back of the device under Haslo sieci Wi-Fi: .....

No, it has nothing to do with the fluid. I assume you mean the speed. With an SD card, the thing acts as a USB stick and as 5G access. Works perfectly even with an iPad that doesn't have 4/5G

Hello, no it doesn't, it acts like a CPE, does NAT from WAN to LAN, which makes it quite secure. But no, it does not have an actual firewall.

Thanks for the tip, I have just reported the error. According to the manufacturer, a bandwidth of up to 1830 Mbit/s can be achieved.

The router requires a power supply unit with a USB-C connection, as it is supplied with power via a USB-C interface. This enables a flexible power supply, be it via a mains adapter, a smartphone or a power bank.

The device can be operated directly from the mains adapter as it does not have a battery and is powered via a USB-C port. Information on whether external antennas can be connected is not included in the data provided. It may be helpful to consult the manufacturer's official documentation or ask ZTE directly.

Hello, To tell the truth, with the images, I didn't have to look for instructions. What's more, depending on your phone, you can use the translation application to translate the message instantly.

Yes, the ZTE F50 5G router supports the use of a SIM card. There is a SIM card slot that accepts a single SIM card.
