MiFi gives you the power to set up a mini WiFi network with 4G internet speeds.
You can connect your tablet, laptop, handheld games console or anything else to it, even when you're out and about.

To do this, you need your own MiFi device – it’s a wireless, credit-card sized piece of kit that can easily fit into your pocket. Then just pop a DataOnly SIM into it, and you’ll create a localised WiFi signal that can be shared by as many as
10 internet-enabled devices.

How many people can connect to MiFi at once?



Wireless MiFi lets you connect up to 10 people at once. It's a great option if you're with work colleagues, fellow students or friends who need to stay connected for any reason - work, study or play.


To find out more, check out iD Mobile’s MiFi information webpage. It includes details of the products and plans currently available.

Just wanted to highlight the significance of this phrase as we wouldn't want customers using their normal contract sims from mobile phones (which include mins/texts), as they cannot be used for tethering purposes as it is against your terms of service.

Tethering is when you use one of your mobile devices (connected to the internet) as a modem for another device - usually a laptop or a Wi-Fi-only tablet.

Tethering price informationPlease note that we do not allow tethering on any of our current plans. If you do use this service it is likely to use up large amounts of your data allowance very quickly, and you will be liable to pay any charge that may occur if you go over your allowance. Please check for updates on our website as this may change in the future.


You may want to update that page include that your own Mi-Fi devices with an Data Only sim are allowed to tether upto 10 devices and that normal contracted packages are not allowed to be used for tethering.

Edit: My bad, it does seem you have added an section for 'Mobile Broadband'. It did seem a bit confusing to me, but it does seem that Mobile Broadband (Mi-Fi) is different to tethering.

Tethering (using your mobile phone to create an Wi-Fi hotspot for other devices) is different to using Portable Broadband devices (such as Mi-Fi, which are dedicated devices for sharing internet connections), however, tethering is not allowed in any form but Portable Broadband Devices are allowed only with the exception of data-only sims.

A couple of questions though (for clarification), which others may have if they may be interested in this.

Is only your type of kit (Huawei Mi-Fi) device allowed for sharing internet with an Data Only plan or can any Mi-Fi device be used?

Can you use the same Huawei Mi-Fi device bought elsewhere but configured with your APN for use with your data only plans?

How do you distinguish the difference between Mi-Fi and Tethering? Would an tablet (capable with SIM based cellular networks) with an data-only sim be able to tether?

I am assuming some type of packet inspection is occurring to inform you if an MI-FI device is present.

If devices are using the Mi-Fi network, I should expect some form of data compression or limit is used as many devices will consume a lot of data. I'd imagine Windows Update using more than a couple of gigabytes if its downloading a new build. (Though this is probably more of an device involved question and not your network)

As a precaution you could enable metered connections in Windows 10 to prevent these type of updates.
