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 Three 4G Hub, which is a 4G home broadband router that enables you to share internet with up to 64 devices simultaneously and supports speeds up to 600Mbps. As this is meant for the home it’s 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. Calculating your data use can be tricky, but if you already have a mobile broadband device then your network likely keeps a log of how much data you use with it each month if you view your account.
