There are a few options on the network. Firstly there’s the Huawei E5573bs-322 4G Mobile Wi-Fi, which is a portable, battery-powered device that allows you to get up to 10 devices online simultaneously wherever you are (as long as you have signal on Three).

Alternatively, there is the HomeFi 4G Home Broadband router, which enables you to share internet with up to 32 devices simultaneously and supports speeds up to 150Mbps. As this is designed for use in the home it’s mains rather than battery powered.

The latest addition is the Huawei B535, which is very similar to the Huawei HomeFi but supports faster 300Mbps speeds and you can connect up to 64 devices at the same time. It also requires a mains supply.

Then there’s also the Huawei AI Cube, which is also designed to replace conventional home broadband, so it needs to be plugged in, but it can get up to 64 devices online at once, offers the higher 300Mbps speeds and also works as a smart speaker, as it has Amazon Alexa built in.

Vodafone

Vodafone have now introduced unlimited mobile broadband plans and are the only network currently offering 5G data.

Use an unlimited voice SIM in a tablet or dongle

One way to get unlimited mobile broadband is to buy an unlimited voice SIM on Three and use it in a Mobile WiFi device or dongle to tether data to other devices. Three now allows the use of voice SIMs in mobile broadband devices and has no tethering restrictions.

The only thing to consider is you'll need to acquire a dongle or Mobile Wi-Fi dongle seperately and order one of the SIM plans listed in the table below.

GiffGaff, Lycamobile and Virgin Mobile also offer unlimited voice SIMs, but either don't allow you to use them in a tablet or dongle or have restrictions to how much data you can use. Smarty Mobile also has an unlimited data plan but hasn’t published whether it works with tablets and dongles.

GiffGaff, Smarty, Vodafone and Virgin are the only other networks to offer unlimited voice SIMs, but don't allow you to use them in a tablet or dongle.

Tether (personal hotspot) your phone to share unlimited data

Another option that effectively delivers unlimited broadband is to use your phone to share data to other devices over a personal Wi-Fi hotspot. Three's unlimited plans, listed above, are suitable as they don't have any tethering restrictions.

This is a great option, but the downside is tethering quickly drains a smartphones battery, so you'll need to keep it plugged in or charge it frequently.

Of the other networks with unlimited data plans, Virgin Mobile and Smarty Mobile also let you tether without restrictions, though note that you have to be a Virgin Media customer to even get unlimited data on that network.

Do you really need unlimited data?

If none of the other solutions are suitable then you might consider if you actually need unlimited data.

If you’re using mobile broadband instead of Wi-Fi at all times then you may eat through 30GB+ of data every month, and if you’re also heavily using it for streaming video and the like then in that case unlimited data might be helpful.

But if you’re using mobile broadband as it’s designed – which is for when you’re out and about, travelling, or having short-term Wi-Fi issues, then even if you use mobile broadband heavily with multiple devices connected you should be fine with a high but not unlimited amount of data.
