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.

Plans unlink after 24 months

After 24 months you can: keep your Airtime and Device Plans without changing anything, Cancel your Airtime Plan and keep paying off your Device Plan instalments or, Cancel your Airtime Plan and pay off your Device Plan in full. For customers who took out an O2 Refresh custom plan before the 17 December 2021, the Airtime and Device Plans remain linked for the duration of the Device Plan, this means you will have to pay off your Device Plan in full if you decide to end your Airtime Plan at any point (but we won’t charge you an Early Termination Charge to exit your Airtime Plan).
