Why This Matters to Your Safety
Beyond merely being interesting to watch the continuing trend to cell phone only households, this highlights the need for increasing your cell phone security. As cell phones get smarter and feature more functionality, the risks of malware increase.
To offset increased risks, keep an eye out for threats reported against mobile phones with your operating system and through your carrier, check to see what security protections there are for your specific phone, and practice good cell phone hygiene – including password/pin protecting your phone.
