What is a dongle?
A dongle is simply a small device that can be plugged into a USB port to add extra capabilities to laptops, PCs, tablets, Raspberry Pi’s, TVs and other electronics.
While there is a plethora of use cases for these dongles, this article covers a category known as ‘internet dongles’ that enable internet connectivity in devices that lack the hardware to connect to the target network.
See our section on alternative dongles to see other examples that are also very useful for businesses.
What is an internet dongle?
An internet dongle is simply a USB device that acts as a mini modem for internet access through cellular networks (i.e. the same networks used by your smartphone: LTE, 3G, 4G or 5G).
This enables all essential work devices like laptops, Raspberry Pi’s, desktops and even some tablets to have internet access when fibre broadband in the form of WiFi or Ethernet is unavailable.
The caveat is that all internet dongles require entering a contract with a mobile provider, such as EE, Vodafone, Virgin Media, etc.
There are however, two distinct types of internet dongles which we will cover in detail:
💡 Availability: Most mobile broadband providers in the UK no longer offer WiFi dongles. See our section on WiFi dongle procurement to find out the best way of acquiring one.
What is a WiFi dongle?
A WiFi dongle (also known as: USB network adaptor, USB WiFi hub, internet stick, or mobile stick) is the original mobile internet dongle.
It plugs into a device’s USB port to enable mobile internet connectivity. Most models are simultaneously WiFi routers that can emit a WiFi signal for others (just like a smartphone hotspot) for other devices to connect to.
This means that you can have your USB internet dongle connected to your laptop, emitting a WiFi signal that can be picked up and used by other people’s devices within a remote location, essentially creating a ‘remote office’.
What is a MiFi device?
MiFi devices are an upgrade to the original (and still relevant!) WiFi dongles. They work in pretty much the same way, but instead of being plugged into a USB port, this new piece of technology works as a stand-alone WiFi router that doesn’t need plugging in as it has its own battery.
This means that as long as it can receive a signal from any cellular network (LTE, 3G, 4G, 5G) it can provide internet connectivity wirelessly while stored in a bag, pocket or simply being placed on a tabletop.
It uses the latest WiFi standards to provide a powerful high-speed signal that can support on average 32 simultaneous users, making it the ideal solution for groups of digital nomads in remote offices.
Also known as ‘mobile WiFi hubs’, ‘pocket WiFi’ or ‘portable hotspots’, these devices are the culmination of improvements in battery, WiFi signal and cellular network technologies. Such is the leap in convenience and capabilities that most mobile broadband providers no longer offer WiFi dongles.

Why are internet dongles useful?
Here are a number of reasons why using either a MiFi device or a trusty WiFi dongle is great for remote working. Not only is it more secure than public WiFi, but it’s more performant than using your smartphone as a ‘hotspot’:
Remote working: They enable remote working from various locations without appropriate WiFi coverage or access, opening up opportunities for digital nomads to open temporary offices in beach cabins, mountain huts, trains, cafes, bars, restaurants, parks, etc.
Security: Connecting to the internet using a password-protected and encrypted dongle or device is more secure than using any public WiFi such as those available in airports, museums, cafes and bars, even when using a VPN.
Performance: These dongles are purpose-built and provide the most stable connection possible from the signal of cellular networks. They are regarded as superior to using a smartphone’s generic hotspot capabilities, which are the most common way of tapping into 4G or 5G.
Procuring an internet dongle
While MiFi devices are best acquired through a mobile broadband comparison, USB internet dongles are best acquired from distributors or websites like Amazon and eBay.
Buying a dongle from Amazon or eBay
When buying a dongle from an online retailer, it’s important to acknowledge that it is very easy to make a mistake. This includes mistaking them with ‘legacy’ WiFi dongles that are actually adaptors for devices that lack wireless capabilities.
Make sure the dongle has a SIM card slot and that the frequencies it receives are correct for the UK.
How much does a dongle cost?
An ad-hoc dongle can be acquired online by your business for as little as £29, but for this to work, you will also need to have a mobile broadband data SIM card to insert and will need to pay for the running costs of this mobile broadband plan from your network provider. This cost will depend on your desired data limit, speeds, and contract length.
Most mobile phone companies offer a MiFi device for free when taking out their mobile broadband deals. Most providers offer a monthly data plan for as little as £20 on a 24-month contract.
