Consumers may be keen to recycle their mobile phone and upgrade to a new handset after learning how the devices have helped to save two lives.
Lara Williams was driving in Gloucestershire last year when she was injured in a car crash.
The 39-year-old was stuck in a ditch and could not identify her location when she rang the emergency services.
However, they were able to trace the signal from her mobile phone and use this information to track her down.
Ms Williams commented: "I don't recall details of the accident and it's only in the last few weeks that I've been getting my memory back properly.
"After hearing the tape of my 999 call back again, I think the whole rescue was absolutely phenomenal and the communication was fantastic."
Her mobile phone also proved useful because Ms Williams was in a semi-conscious state after the accident.
Therefore, emergency call operator Will East kept talking to her while the search for her vehicle was underway
Ms Williams credited Mr East with keeping her going throughout the ordeal, as he was very calming and reassuring.
Another incident involving a mobile phone owner in distress occurred this week in Snowdonia.
Two men tried to climb Ordinary Route on the Idwal Slabs last Saturday afternoon (Jan 22nd 2010).
However, the pair forgot to take their torches, which meant they could not find the path when darkness set in.
They eventually rang for assistance and Ogwen Valley Mountain Rescue Organisation sent 18 people to help.
Since the pair could not identify their precise location, they used a mobile phone to send out a light to the rescue team.
The glow of the handset was spotted and the two men were eventually recovered.
A spokesman for Ogwen Valley Mountain Rescue Organisation said the walkers got into trouble partly because they started their hike "rather late in the day".
