The availability of dongles is negating the need for use of a landline to access the web, according to one expert.
Barry Collins of PC Pro magazine told the Guardian that those who use the internet sparingly may turn to the plug-in USB sticks in order to save money and avoid the inconvenience of lost connections.
He told the Guardian "If you're just a light internet user and want to watch a bit of video online, or download a few tracks, then you'll find dongles are really good for general surfing."
Continuing "There may be a bit of a speed trade-off but as long as you have good mobile phone reception, you should be able to get a strong broadband connection through a dongle."
Savings in the region of £60 to £120 a year have been quoted for those switching to pay-as-you-go mobile and providers such as O2, Orange, Vodafone and T-Mobile.
3 is offering a dongle package with 2.8Mb and a download allowance of 1Gb a month for £10 a month.
