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 £13/month, or from £22/month with unlimited data on Three. The device is a cheaper alternative to the Huawei 4G Plus MiFi (Huawei E5783B) offering slower download speeds but in a cheaper and more portable form factor.

In this article, we’ll review the Huawei E5573bs-322, including the price plans available and how the pocket router works. We’ll then look at how this compares to other mobile broadband solutions like the Huawei 4G Plus MiFi or using a mains-powered device like the Huawei B535 HomeFi+. 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.

At present, Three offers a choice of two mobile wi-fi hotspots: the Huawei E5573bs-322 Mobile Wi-Fi hotspot and the Huawei 4G Plus E5783B MiFi. The Huawei E5573bs-322 is the cheaper of the two devices, available with unlimited data for just £22/month.

The following table shows a list of currently available price plans for the Huawei E5573bs-322 Mobile Wi-Fi hotspot:

20GB Data24 month contract£0£13/month
12 month contracts
Unlimited Data12 month contract£19£23/month

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 20GB data plan at £13/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 entry-level 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.

Alternatives

Huawei 4G Plus MiFi

The Huawei 4G Plus MiFi (Huawei E5783B) is a newer mobile wi-fi hotspot device from Three. It offers download speeds that are up to twice as fast as on the Huawei E5573bs-322, with support for Category 7 LTE connectivity (up to 300Mbit/s download and up to 100Mbit/s upload). You’ll also be able to connect up to 16 devices at the same time, with support for faster dual-band Wi-Fi 5 (802.11ac) connectivity.

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:

Coverage

In the UK, Three offers 99.8% population coverage on 4G and 98.3% population coverage on 3G.

Before buying the Huawei E5573bs-322 Mobile Wi-Fi Hotspot, we strongly recommend double checking the coverage in your area. You can do this by entering your postcode on Three’s online coverage map:

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.

  • Hi,

    I have a 3 mobile wifi (Huawei E5573bs-322 4G), I can’t see the wifi extender feature on the web management page, could you please advise on how to use this mobile wifi as a wifi extender (access the internet using wifi network)?

    Many thanks

    • Hi Ibrahim,
      Thanks for your comment. I had a quick look at the manual for this device and it seems like you might need to enable the feature through Huawei’s HiLINK app?
      Ken

        • Hi Ken,

          Just to let you know, I checked the Huawei’s HiLink app and also the Huawei’s AI Life app as well. I couldn’t find anything about the wifi extender.

          In the manual shipped with the device, it says the wifi extender function can be enabled from the management webpage (http://192.168.8.1 or http://192.168.9.1), I accessed that webpage but couldn’t find anything related to the wifi extender.

          Any advice?

          Many thanks,
          Ibrahim

          • Hi Ibrahim,
            That’s really odd. I’m not sure the answer to this, I’m afraid. It’s possible this feature might not be provided on the version of the hotspot from Three – I’ve never actually seen it advertised anywhere. It might be worth checking with Three or Huawei Customer Services to see if they’re able to shed any light on this?
            Ken

      • Hi Ken,

        Thank you for your reply.

        I think the wifi extender feature is not provided on the version of the hotspot from Three. I’ve seen that this feature is provided on other versions (from MTN, abroad) but not on the one from Three in the UK. I’ll check with Three.

        Many thanks,

  • Hi there,

    I’m very keen to get one of these wireless routers but have a quick question.

    I live on a boat in London and I rely on a 12v system for electricity. What is the voltage of this device?

    Also can it be charged using a usb lead or only a mains adapter?

    Many thanks!

  • Having bought a Three unlimited data sim and a 4g mifi as above so my wife can work from home, I can only report it is pretty useless with data speeds as slow as 0.96 download and 0.35 upload speeds.. but if she uses her phone as a hotspot instead which uses a Virgin sim, she is getting 17.5 download and 7 upload from the exact same location… so not impressed at all.

    • where about in the country are you using the device?
      I am thinking of buying the 535 as its faster than the 5573 on the three network.
      If your network is saturated in your location this could be the problem?
