Mobile broadband deals may seem like a strange concept but in actuality they make complete sense. You've got traditional forms of internet to get you online, why not continue that connection when you head out?

Very simply (as you've most likely guessed from the name) mobile broadband is internet you can take on the move. Most commonly, it comes as a hub you can connect your phone, laptop and other gadgets to, however there are a few different options.

Dongles, routers, SIM cards - all servicing different needs. And with PAYG options, contracts and simply big upfront spending plans, there is a lot to consider when investing in any mobile broadband deals.

Of course, Mi-Fi isn't for everyone and anyone with a big data mobile phone deal or SIM only deal will likely find mobile broadband redundant with tethering abilities and anyone needing it for their home will find 4G home broadband to be a better option.

However, for parents trying to keep kids entertained on long trips, people trying to work on trains or people who simply travel abroad a lot, mobile broadband deals could well be a logical option for you.

What is mobile broadband and how does it work?

Mobile broadband (commonly known as Mi-Fi) is in essence a portable internet router. It can come in multiple forms - dongles, hubs, SIM cards etc - and simply provides you reliable internet when you're out and about.

Unlike regular broadband deals or even 4G home broadband plans, the major pro of these routers is the ability to take them on the move. It doesn't (in most cases) require a plug or any power and most options are small and portable.

Depending on what kind of option you choose, you can use it tether multiple devices or even get unlimited data on the move.

Where can you find mobile broadband deals?

Mobile broadband from Three:

Three Huawei 4G Mobile Wi-Fi | £0 upfront | 24 month contract | 20GB data | £10 a month
The first thing you'll notice about this offer is its temping name - the Huawei E5573bs-322 - if that doesn't captivate you, we don't know what will! While there is a host of different packages at different price points, we feel the best option is the 20GB data package. It is one of the cheapest options and comes packed with more data than most. However, it is a 24 month contract so some might want something shorter.View Deal

Three PAYG Huawei 4G Mobile Wi-Fi | £89.99 upfront | valid for 24 months | 24GB data
Don't want to sign up for a contract? You don't have to. With this offer you're getting the exact same hub as above but without being tied into monthly payments. While there is a few PAYG options, we feel like the most expensive one is worth the investment. It comes with 24GB of data and stays valid for 24 months. (once you click through, you'll find PAYG at the bottom of the list).View Deal

EE 4GEE Wi-Fi Router | 24-month contract | 30GB data | £20 a month | £30 upfront

Can I get 5G Mi-Fi plans?

Yes you can! Despite 5G still being quite a new introduction to the world of Wi-Fi and phones, you can now get 5G mobile broadband deals. EE is the first network to jump on the trend, offering up its 5GEE router

This can be used either as a router at home or on the go. However, keep in mind that you may need to have 5G capable devices to use it, read through EE's terms and conditions to make sure you can make use of its 5G router before buying.

How is Mi-Fi different from Wi-Fi?

There are a few key differences between the two. Firstly and most obviously, with broadband deals you need to have a landline and go through the set-up process. That means that broadband can only be installed in a home, office or stable location.

Mobile broadband on the other hand can be taken on the go and requires no set-up to get started. While Mi-Fi will remain faster than ADSL (slower broadband) in most cases, it will struggle to match fibre in its consistency and speed.

If you can get a home broadband deal where you are, we would advise that as your main Wi-Fi connection due to its affordability, consistency and overall performance. Can't get it where you live? Mobile broadband could be the perfect option.

Can I use mobile broadband at home?

While you can use one of these routers at home, a regular broadband package will perform much better (see above). However, not all homes can get Wi-Fi or you might just prefer a more flexible internet model.

Mobile broadband works off of 4G (and depending on which deal you choose, 5G) connections instead of the cables regular Wi-Fi uses. That means that a Mi-Fi router could well work as home broadband...if you have good 4G signal.

If the signal is poor, you will find it to be a frustrating model for your internet plan.

What alternatives are there to mobile internet?

There are a few alternatives to mobile broadband depending on what you need it for:

Mobile phone deal/SIM only plan:
Phone plans have come leaps and bounds in recent years in terms of their data caps. With options offering unlimited data or just large plans, you can easily tether a few devices off your phone and skip the portable router. This can however get quite expensive quite quickly with big data plans costing a fairly large price.

- SIM only deals
- Mobile phone deals

Broadband plans:
Just need internet in your home? Regular broadband will most likely be a better option for you. In most cases, it will be cheaper, faster and more reliable, if you don't mind the longer contracts and set-up fees of course.

- Broadband deals
- Fibre broadband deals

4G Home Broadband:
A cross between mobile broadband and home broadband, 4G home broadband offers a flexible alternative to the above. In most cases it needs a plug and won't be as portable as somme of the options on this list but doesn't require a set-up or long contracts.

Are Mi-Fi routers faster than regular broadband?

This isn't so much a simple yes or no answer. With so many different broadband deals out there ranging from painfully slow to blisteringly fast, mobile broadband falls somewhere in the middle.

It will easily out-perform the lower end deals but as you get into the faster fibre category you will find it losing out. These portable internet routers also require strong 4G connection meaning speeds will change depending where you are, regular broadband on the other hand will more or less stay the same.
