Three’s Mobile Wi-Fi Hotspot (Huawei E5573bs-322) gives you 4G mobile broadband on up to 10 devices.

If you’re looking to get devices like your laptop or tablet connected to the internet, it can be useful having a mobile wi-fi hotspot like the Huawei E5573bs-322 (also referred to as the Mi-Fi). This portable battery-powered hotspot uses a 4G connection, creating a wi-fi network from it for your other devices to connect to.

You can get the Huawei E5573bs-322 Mobile Wi-Fi hotspot from as little as £9/month on Three. You’ll pay £22/month if you want unlimited data on a 24-month contract from Three. Alternatively, shorter 12-month and 1-month plans are also available if you want extra flexibility.

In this article, we’ll review Three’s Mobile Wi-Fi Hotspot, including the price plans available and the Huawei E5573bs-322 pocket router. We’ll then look at how this compares to other mobile broadband solutions such as tethering from your smartphone or using a mains-powered device like the Huawei B535 HomeFi+ or the Huawei AI Cube B900. We’ll also look at the coverage and download speeds available when using a MiFi on Three.

Mobile Wi-Fi Price Plans

In the UK, Three is notable for offering mobile wi-fi hotspots (Mi-Fis) as a way for you to get multiple devices connected to the internet. You can use a Mi-Fi to connect up to 10 devices wherever a 3G or 4G mobile signal is available.

For most people, we’d recommend the £22/month unlimited data plan, especially if you’re making heavy use of the mobile wi-fi hotspot across multiple devices. Alternatively, if only want to use it from time to time, consider the 40GB data plan at £13/month or the 20GB data plan at £10/month.

You’ll get the Go Binge service included on all Pay Monthly price plans with at least 15GB of data per month. This gives you unlimited data for use on Netflix, TV Player, Snapchat, Soundcloud, Deezer and Apple Music. Usage of these services won’t count towards your normal download allowance.

The Go Roam service is also included on all Mi-Fi price plans, allowing you to use your mobile wi-fi hotspot at no extra charge when abroad in 71 destinations. This includes most European countries along with the USA, Australia and more.

Mobile Wi-Fi Hotspot

The Huawei E5573bs-322 is Three’s latest mobile wi-fi hotspot. It’s a pocket-sized battery-powered 4G hotspot, allowing you to access the internet on up to 10 devices at one time.

According to Huawei, the E5573bs-322 has a 1500mAh battery that can give you up to 4 hours of battery life on one charge. In practice, actual battery life can vary depending on the number of devices you use and depending on the strength of the 4G signal in your area. If the battery runs out, it’s possible to recharge it using a micro-USB cable which is included in the box.

The Huawei E5573bs-322 supports Category 4 LTE connectivity. This can give you download speeds of up to 150Mbit/s and upload speeds of up to 50Mbit/s. In reality, however, actual download speeds are normally slower than this: speeds of around 15Mbit/s are much more typical (depending on your location and the strength of your 4G signal).

The mobile wi-fi hotspot weighs 75g and has three LED indicators on the front of the device. This gives information about your 4G connection, whether you have any unread text messages and the amount of remaining battery life on your device. There’s also a micro SD card slot on the hotspot, allowing you to insert a micro SD card with up to 32GB of storage.

For the full specifications of the device, please see Three’s website.


4G Home Broadband

As an alternative to a portable mobile wi-fi hotspot like the Huawei E5573bs-322, you can choose a mains-powered 4G home broadband router instead. Being a mains-powered device, you’ll get less flexibility to bring the device with you to use in other locations. You will however get a more powerful router with a larger antenna, faster download speeds, stronger wi-fi and the ability to use more devices at the same time.

For most people, the Huawei B535 HomeFi Plus is our recommended 4G home broadband router. With the Huawei B535, you can access up to Category 7 LTE speeds (up to 300Mbit/s download and up to 100Mbit/s upload). This is double the maximum download speed available on the Huawei E5573bs-322.

The Huawei B535 supports dual-band 802.11ac wi-fi, with up to 64 devices able to connect to your wi-fi network at the same time (versus just 10 devices at one time on the Huawei E5573bs-322). You’ll also get 4 Gigabit Ethernet sockets for connecting a wired device to your network and two SMA sockets for attaching an external antenna if required.

The Huawei B535 HomeFi Plus is available on the following price plans from £20/month:

As an alternative, you can get the Huawei AI Cube B900 for an extra £5/month. This is a two-in-one device that doubles up both as a 4G home broadband router and as an Amazon Alexa smart speaker.

Tethering Through Your Phone

If you have a fairly modern smartphone and a large enough data plan, you can tether through your mobile phone instead of using a separate mobile wi-fi hotspot. Whilst you’re tethering, you’ll be able to use your smartphone’s normal data plan so this may sometimes work out to be cheaper than using a separate Mi-Fi with its own plan.

If you have an unlocked smartphone, consider switching to one of the following unlimited data plans on Three:

12 months
24 months
1 month
12 months
1 month

For more information, see our full guide to tethering on UK mobile networks. You may also find it useful to read our guide to unlimited data plans in the UK.

If you’re travelling abroad, it’s possible to use your Mi-Fi at no extra charge in 71 destinations. This is possible through the Go Roam offer, which covers most of Europe, the USA, Australia and more.

If you’re looking to use the service in a more rural area, consider getting a mains-powered device like the Huawei B535 instead. This will normally give you better coverage and faster download speeds, along with the ability to attach an external antenna to improve both of these things.

    Would you be able to connect a games console to the MiFi and play online? And roughly how much data does a console use?

    • Hi Elliott,
      Indeed, you can! Simply connect your games console to the wi-fi network produced by your Mi-Fi. Unfortunately, there isn’t a simple answer to how much data this uses – it really depends on the game you’re playing and whether you’re doing things like downloading updates, etc. Therefore, it’s worth just keeping a very close eye on data usage when you start playing your games.

  • Alison Black said:

    I have been asked to work from home, but have no land line. I also travel a lot, both in the UK and abroad and would like to be able to access my own wifi.

    If choosing between home-fi (such as AI cube/Huawei B535 router) or mi-fi Huawei E5573bs-322 4G Mobile Wi-Fi which would you opt for?

    Located in a large village near the sea in Devon, good mobile 4g coverage

    • Hi Alison,
      That’s a very good question! It really depends on whether you want maximum performance in one fixed location (i.e. for use at home) or whether you want the flexibility of working in multiple different places. If you’re mainly using it at home where a mains power supply is available, I’d choose to go with the Huawei B535. It’ll give you better performance along with the option of using an external antenna, etc. The MiFi is a battery-powered device so may give poorer coverage/speeds/etc but you do have the flexibility to use it in multiple different places.
      Hope this helps,

    We have 3mobile WiFi 17BF. Which I charge after approx 4 hours use. Would it be ok to leave on charge while surfing?

    • Hi Elizabeth,
      Thanks for your comment. I’m not familiar with the device in question but generally, it should be absolutely fine to leave the device plugged in & charging whilst you use it.

  • Hans Sluiman said:

    An alternative portable Mi-Fi device that may be of interest to people who prefer Pay As You Go is Bitebird’s offering ( It works in a slightly different way than Three’s Pay As You Go price plans in that you buy a certain amount of credit (the minimum amount is €25 for which you receive €30 worth of credit) which has a validity of one year. It can be used in 141 destinations but the rate per MB varies: in Europe and many other countries in Asia, America and Oceania you are charged €0.01 – €0.03, although in USA the price of 1 MB is €0.19. The good thing is that in several countries more than one local mobile telephone provider can be used (for example in the UK both Three and O2 networks are supported). What I like most is that a modest top-up of €30 will last 12 months whereas Three’s cheapest £39.99 offer of 1GB lasts only 1 month. Bitebird uses a Huawei 4G device (similar but not identical to Three’s device) for which there is a one-off charge of €100 although periodically (e.g. in the run-up to Christmas) a discounted price is offered. Bitebird may be of interest to light mobile internet users who travel overseas relatively infrequently or are travelling to countries that are not included in Three’s Go Roam offer.
