We like the Wherifone as an added safety measure to give busy people with young kids and elderly parents peace of mind. The Wherifone is a GPS cell phone for children and seniors. Itâ€™s easy to locate the device online or by phone with the GPS location service. The phone itself has three programmable one-touch dial buttons; an â€œSOSâ€ button for 911, and a 20 number phone book. Controls allow the person paying the bill to limit phone calls, and/or restrict text messages and game downloads so they are not surprised when the bill comes. The phone comes in blue, black, silver, purple and pink, and retails for $99.
