Can I get a data only SIM with unlimited data?

Yes, unlimited data only SIM plans for use in tablets and mobile broadband devices are available on 1-month, 12-month and 24-month contracts from £22 a month.

What are the differences between Three's broadband devices?

The selection of mobile broadband devices that can be had with unlimited data include the Huawei 4G+ Mobile WiFi ,which is a portable, battery-powered device that supports speeds up to 300Mbps and enables you to share internet with up 16 devices at the same time. 

There’s also the Three 4G Hub and Three 4G Plus Hub, which are 4G home broadband routers that enable you to share internet with up to 64 devices simultaneously, and support speeds of up to 600Mbps. As this is meant for the home they're mains powered, but can be taken anywhere with mains power.

On the 5G front, there’s the Three 5G Hub, which is a 5G home broadband router, so like the 4G Hub it needs plugging in, but it supports much higher speeds, theoretically reaching up to 2.33Gbps. Real world speeds are a lot lower, but can still rival fibre broadband. It also supports 64 simultaneous device connections.

Do you really need unlimited mobile broadband?

It’s always worth checking how much data you actually need, since there’s a good chance you might not need unlimited data.

In fact, if you’re not planning to use mobile broadband much or will mostly just be using it for web browsing and social media (as opposed to video, big downloads, music, and online gaming), then you shouldn’t need a vast data allowance.
