Mobile phone users are putting their personal data at risk by not having security software installed, according to the Carphone Warehouse.
New research released by the firm showed more than half of UK adults think their information is secure, with 49 per cent using phones to buy goods online, potentially leaving account details at risk.
Meanwhile, nine out of ten people do not have any security software in place on their smartphone, it added, even though the same proportion do so on their personal computers.
Launching Mobile Security Week, the Carphone Warehouse said thieves are on "high alert" for opportunities to bag new handsets at the moment, making mobile security increasingly important.
The firm highlighted several simple ways to keep data away from fraudsters, including recording a phone's identity number, securing access to voicemail, being wary of Wi-Fi hotspots and always backing up data.
