FAQs

What does a WiFi USB do?

A WiFi USB improves your device's WiFi performance either by making a more reliable connection with your active wifi network or establishing a new SIM-based connection over a 3G, 4G or 5G network. With the TCL WiFi Dongle, for instance, you can enjoy high-speed 4G straight to your Windows, Mac or other device with a USB port.

Is the TCL 4G Dongle reliable?

Yes, the TCL 4G Dongle is a reliable device that provides stable 4G connections in most places where 4G is available. The dongle's external antenna interfaces also provide you with a fast connection in areas with poor signals.

How do you set up the TCL WiFi Dongle?

It's easy to set up your TCL Dongle. You just need to insert your O2 SIM card into the dongle then plug the USB into your Mac or Windows PC. Now you can connect to O2's reliable 4G network in seconds.
