I'm sorry, 911 is out of your calling area...

If there's one number cell phone users can remember it's 911 in case of an emergency.

But if you're the owner of a Samsung Jitterbug, you had better be in your carrier's service area or help won't be coming. The phone has been recalled by Samsung Telecommunications America, the U.S. Consumer Product Safety Commission reported.

If you are in the wrong place at the wrong time you could get the message "out of range, try again later" -- not the most reassuring message when you're frantically dialing 911 for help.

Jitterbug is being marketed to seniors and others who might be inclined to take advantage of its simplified design with large, easy to use keys.

Samsung or its distributor, Jitterbug, are supposed to contact each customer to give them a software upgrade. The affected ,models are SPH-a110 and SPH-a120 with standard key pads and version BB14 software.

If you have one and have not been contacted, call Samsung at (866) 304-4980.

Jitterbug says the glitch shouldn't affect most customers. Its vice president of customer service said the main problem would be for those in rural areas where there is limited cell service.
