What is a wifi dongle?

A wifi dongle is a small USB stick that allows you to access online services without needing to connect to Wi-Fi. These pocket-sized devices can be connected to your smartphone, tablet or laptop for easy internet access when travelling. They’re also referred to as mobile broadband sticks, USB modems, internet sticks and USB network adapters.

Wifi dongles are popular as they offer much better flexibility than fixed-line connections and can be used on the go. The connection provided by a wifi dongle can be used to access the internet, share this connection with friends, download/share files and more, so it isn’t hard to see why an increasing number of people are using them.

How does an internet dongle work?

To get your internet dongle working, it needs to be plugged into your laptop or computer’s USB port, where it can then act as a portable modem. Once plugged in, the dongle then connects to the internet in the same way as your smartphone to offer the user 3G, 4G or 5G connectivity. 

Some wifi dongles don’t connect through your laptop or computer. Instead, they operate independently to provide you with Wi-Fi connectivity through cellular data.

How do I get a dongle and what do they cost?

Because dongles are supplied by mobile network providers, the process of getting yourself one is really simple! In the same way that your mobile phone comes with a monthly contract or pay-as-you-go, the same applies to broadband dongles.

For example, if you buy a dongle from EE, then your laptop will hook up to the EE network once the dongle has been activated. 

Pay-as-you-go is the best option if you rarely require mobile broadband access (or aren’t exactly sure how much data you require). Here, you’ll pay around £30 to £50 upfront, and can then top up as and when you need more data. 

With a monthly contract, you’ll receive the dongle for free but can expect to pay around £15 a month on a 12 to 24 month plan. Picking an unlimited deal will cost more but won’t restrict your data usage each month.

You can find and explore wifi dongle deals through a comparison site like Money Supermarket.

What are the advantages and disadvantages of wifi dongles?

Advantages

• Mobile broadband can be easily set up without an engineer appointment

• When you take out a contract, dongles are supplied for free

• You can only connect one device at a time (and this device will require a USB port)

• Mobile broadband often has monthly data limits

• While overseas charges have come down, it’s still expensive to use a dongle abroad
