Mobile broadband users should ensure they seek out the product best suited to their needs when they select a dongle, it has been claimed.
According to This is Money, one of the key issues for web customers is network coverage.
The site said that since mobile broadband works all over the UK, anybody with a laptop and a dongle should be able to access the internet.
However, it noted that coverage "can be patchy" in some areas, potentially limiting user service satisfaction levels.
This is Money urged web users to check Ofcom's UK coverage map to ensure the provider they have chosen "cuts the mustard".
Last week, broadband provider 3 reduced the price of one of its entry-level data mobile broadband packages.
The firm's Broadband Lite deal now offers a 1GB data allowance for £7.50 a month, down from the original price of £10 a month.
