4G is the standard for mobile broadband, and it offers much faster speeds than 3G networks. With speeds up to five times the average UK 3G connection, 4G mobile broadband is a much more viable alternative to ASDL home broadband.

Depending on the type of USB modem, dongle or MiFi you are using, your speed can vary. This applies whether it's a 3G or 4G connection you're connected to. It's worth considering the device you'll be using to connect to the internet when choosing your package.

People using a MiFi may also find that their connection speed is slower when the signal is being shared between multiple devices.


Although 4G coverage has improved in recent years, it still isn't available everywhere just yet, so even if you sign up for a 4G mobile broadband package, you might be connecting to 3G networks more frequently, depending upon your area.
