The Huawei 4G Plus MiFi (Huawei E5783B) allows you to get high-speed 4G mobile broadband on up to 16 devices.

If you’re looking to use 4G broadband at home or when you’re on-the-go, Three currently offers the Huawei 4G Plus MiFi (Huawei E5783) from £10 per month. It allows you to use high-speed 4G broadband, with Wi-Fi on up to 16 devices at the same time.

When you’re using the Huawei 4G Plus hotspot, it will connect to Three’s 4G network with a maximum download speed of 300Mbps. It will use the 4G connection to produce a regular wi-fi network that you’re able to connect to from other devices. This includes your laptop, tablet, smartphone, smart TV and other smart home devices. You can use the mobile broadband service when you’re at home, or when you’re travelling to other locations.

In this article, we’ll review the Huawei 4G Plus MiFi, including the price plans available and the technical specifications of the device. We’ll also compare it to alternative devices like the 4G Hub and 5G Hub, both of which are also available from Three.

Huawei 4G Plus MiFi Plans

If you’re looking for high-speed 4G broadband that you can use at home and outside, Three currently offers the Huawei 4G Plus MiFi on plans from £10 per month (Huawei E5783B-230). This allows you to access 4G broadband on up to 16 devices at the same time, with a maximum download speed of 300Mbps.

When choosing a price plan for your Huawei 4G Plus MiFi, you’ll need to decide how much data you need:

  • The cheapest plan gives you 2GB data for £10. This is the cheapest way of getting 4G broadband from Three. It should be fine for occasional usage (e.g. for the odd trip away from home) but it’s not recommended for regular usage or for things such as streaming.
  • A good balanced option is 40GB data for £17. This will allow you to use the service fairly regularly, including for browsing the web and for streaming video when you’re at home and outside.
  • For regular usage, get unlimited data for £23. You can use this plan as much as you like, without any hidden download limits. You can even use it as a replacement for home broadband if you like. In 2019, the average UK household consumed 315GB per month on their home broadband service. For this reason, you should definitely choose an unlimited data plan for regular usage at home.

Huawei E5783B Hotspot

The Huawei 4G Plus MiFi (also known as the Huawei E5783B or the Huawei E5783B-230) is Three’s latest mobile wi-fi hotspot. This is a battery-powered device that allows you to access 4G broadband on up to 16 devices at the same time. You can use it wherever a 3G or 4G connection is available, including when you’re at home and when you’re out and about.

Compared to Three’s older MiFi hotspots, a key advantage is you’ll be able to access faster 4G+ speeds. The Huawei E5783B 4G Plus MiFi supports Category 7 LTE speeds. This means you’re able to get a download speed of up to 300Mbps and an upload speed of up to 100Mbps (this is twice as fast as Three’s older Huawei E5573bs-322 mobile wi-fi hotspot).

How Does The 4G Plus MiFi Work?

In the background, the Huawei 4G Plus MiFi uses a 4G connection to Three’s mobile network. From that, it produces a secure Wi-Fi network for your other devices to connect to.

By default, the wi-fi network is preconfigured with a default network name and password but you can easily change this through the administration interface on your hotspot. You can also enable a guest wi-fi network if you’d like to share your mobile broadband connection with more security.

The device supports Wi-Fi 5 technology (802.11ac) with dual-band Wi-Fi connectivity. This can give you transfer speeds of up to 867Mbps when using 5GHz Wi-Fi and up to 300Mbps when using 2.4GHz Wi-Fi. According to Huawei, it’s possible for up to 16 devices to be connected to your Wi-Fi network at once (with a maximum of 8 devices connected to 5GHz Wi-Fi). However, Three normally advertises a limit of 10 devices as performance can start to degrade when you connect lots of devices at the same time.

Battery Life & Charging

The Huawei E5783B hotspot has a built-in 1,500mAh battery. This gives you up to 6 hours of usage on one charge. It also gives you up to 350 hours on standby.

The device is charged using a micro-USB cable, one of which is provided inside the box. You can also use the USB cable to connect the device directly to your laptop, where it can be used as a USB modem without the need to enable wi-fi functionality.

If you like, it’s possible to keep your Huawei 4G Plus MiFi plugged in at the wall if you’re mainly using it in one location (e.g. for broadband internet at home).

Design & Form Factor

The Huawei 4G Plus MiFi measures 10.8 x 6.2 x 1.6 cm and weighs 95g. This means you should be able to carry it around in a pocket if required.

The device is available in black. The front of the device has three LED indicator lights to show the status of your 4G connection, any unread text messages and the remaining battery life of your device. It’s a little heavier and larger than Three’s older MiFi hotspots like the Huawei E5573bs-322 but there shouldn’t be a significant or very noticeable difference.

For more information and specifications of the device, please see the Three website.

Alternatives

4G Plus MiFi vs Three 4G Hub

As an alternative to the 4G Plus MiFi, Three also offers the 4G Hub router in selected postcodes across the UK.

Unlike the 4G Plus MiFi, Three’s 4G Hub is only designed to be used for 4G broadband at home. As such, it’s available at a lower price of just £17 per month. It’s also a much more powerful device but you’ll need to have it plugged in to a wall socket at all times. This means you won’t get the portability of the battery-operated device like the 4G Plus MiFi.

    Hi Ken,

    Wow, what a great website you have (add to bookmarks). I’m thinking of switching from broadband to mifi as I get much faster speeds (↓20 Mbps vs ↓110 Mbps, ↑0.9 vs ↑17) on my phone than broadband. This looks like a sweet deal on 3 but I’m concerned that it won’t allow all of my family’s devices to connect (5 Macs, 2 phones, 5 Echo dots, lightbulbs etc. etc. about 24 devices in total). Am I right to think that this will only work with 16 devices (and only 10 are recommended) – if so, are there any better mifi devices out there you’d recommend?

    All bests, Jamie

    • Hi Jamie,
      Thanks for your comment. Yes, I suspect you wouldn’t be able to connect that many devices to the MiFi. There are probably two alternatives I’d recommend:
      1. Are you within the coverage area for Three’s 4G Hub? If so, you’ll get a much more powerful router with the ability to connect up to 64 devices at one time. You can also get it for a lower price of just £17/month at the moment (albeit, without the same portability that a MiFi gives you). You can check the availability in your postcode here.
      2. If not, I’d recommend getting an unlimited data SIM card from Three. You can currently get one for just £16/month. You can then buy an unlocked 4G router like the Huawei B311 from Amazon.co.uk. This will give you a much more powerful Wi-Fi signal and will allow you to connect more devices to your network at the same time.
      Hope this helps,
      Ken

    • Hi Daniel,
      Thanks for your comment. I see no reason why you shouldn’t be able to connect to an Amazon Echo Dot to your Huawei E5783B-230 hotspot.
      Ken

  • Hi Ken. Thanks so much for the info. Two questions:
    – can the router be used in Modem mode- ie. to work with an existing mesh network I have at home?
    – is there a 14 day cooling off period, during which I can return for a full refund (and cancel the contract) if it doesn’t meet my needs?

    Thanks, your friend, Sam

    • Hi Sam,
      Thanks for your comment!
      1) I don’t think the Huawei E5783B would work with a mesh wi-fi system as it doesn’t have an Ethernet port for you to connect that system (for that, you’ll need something like the Huawei B535 instead). I believe there is the ability to use it as a USB modem on your computer but I suspect that probably won’t work with your mesh system.
      2) Yes, you’ll benefit from a 14-day cooling off period on this plan 🙂
      Hope this helps,
      Ken

  • Thinking of purchasing the Huawei E5783B-230 super fast router for my motorhome, can I connect it up to my external antenna ?

    • Hi Andy,
      Thanks for your comment. Sadly, the Huawei E5783B-230 doesn’t support external antenna. You’ll need to choose a different device that does support an external 4G antenna (e.g. the Huawei B535).
      Hope this helps,
      Ken

  • Hi, I don’t know if you can help me. I have purchased the huawei 4g plus mifi router and have an unlimited data SIM from three. It has connected fine to my laptops but I can’t get my smart TV to work with it (we don’t have home broadband at the moment). It says it’s connected and the signal strength is excellent but will not load any data. Do you know if I need to complete some sort of installation process apart from entering the password (already done)

    • I’m in the same position as you with connecting to both my smart tv and also my printer, although there is no problem connecting to my iPhone.
      My previous 3 mifi had no problems connecting to anything – I’m just wondering if the new mifi is locked? Why is it connecting to my phone, though??

  • Hi Ken, Brilliant article. Im interested in getting the 4g home router with three but they have said it is not available in my area. Would it be possible to just get the mifi 4g router from three with the unlimited data sim and then buy the home router B535 separately and add the sim into it instead. As i have a bigger space than 10m (wifi lenght of the Mifi router) I like the bigger home router to be used all around the house rather than carrying the mifi about with me. So is this solution possible to do?
    Many thanks

    • Hi David,
      Thanks for your comment. The Huawei 4G Plus MiFi could certainly work, though you might be better off with something like the Huawei B535 if you need external antenna support. You can read my full article on 4G broadband and 4G antennas for more information, and do let me know if you have any specific questions.

    Hi Ken
    Great article I just recieved my three 4g plus mifi and hoped to use in work.. However I work inside a modded shipping container and it seems to be having a big impact on my signal any suggestions of a workaround to solve my dilemma…

    • Hi Ste,
      Thanks for your comment. Sadly, a shipping container is a pretty good Faraday Cage so blocks a lot of radiation including 4G signals. The best solution would be placing it close to a window or door if there is one. Alternatively, some 4G home broadband routers allow you to use an external antenna which you could place outside the container. Unfortunately, however, the 4G Plus MiFi doesn’t support this.
      Ken

  • Hi,

    I’ve just ordered a MiFi becuase Three’s website shows that home 4G broadband isn’t available for my postcode. However in some of your responses above you recommend a 4G home broadband router such as the B535, and this will take an antenna. Am I right in thinking this won’t be a solution for me if Three can’t offer 4G home broadband in my area. Will I just stick with the MiFi mobile solution for now and hopefully switch when coverage improves (in a rural area). Thanks!

  • Hi Ken, thank you for this article. Do you know if the device is locked to a Three SIM only?
    I was thinking of using it while abroad with a foreign local SIM (the destination is not in the Go Roam list).
    Even if the destination is in their Go Roam list, it sounds like tethering abroad is not allowed though I only understand that it apply to mobile phones, not sure about MiFi devices.

  • James McAlister said:

    I have just bought a Huawei E5783b and the lights only work when t is plugged in is that right or is the much faulty thank you.

  • James Moulton said:

    Hi Ken,
    I am looking into Mifi for a 3 person house in a city center, do you think it is a feasible alternative to standard Wifi for streaming/gaming ect?
    Cheers,
    James

    • Hi James,
      Thanks for your comment. That’s a very good question – it really depends on your usage and how many devices & how much bandwidth you’re likely to require. It also depends on the speeds available where you live. In general, I’d normally advise against using a MiFi for this as it will have a relatively weak Wi-Fi signal (normally up to 10 meters) and will only be able to connect a couple of devices. You’ll get much better performance with a 4G home broadband router like Three’s Huawei B535 or 4G Hub instead. Saying that, if it’s just some basic browsing, a Mi-Fi could be serviceable for some short-term/stop gap usage.

    Hi, enjoyed your review.
    I have just purchased a E5783B and intend to leave it switched on in my caravan when I am absent. Can I leave it on charge for long periods so that it gives a constant WiFi signalis that not a good idea?
