Samsung and the Consumer Product Safety Commission have issued a recall of Jitterbug cell phones, some of which can fail to connect to 911 under some circumstances.

Affected model numbers are SPH-a110 and SPH-a120 with version BB14 software.

The CPSC reports that Samsung and Jitterbug are contacting customers directly to schedule a free software upgrade. If you own one of the recalled models and haven't yet been contacted, call Samsung toll-free at (866) 304-4980.
