Dont think she can handle switching to smart phone. Thought about installing land line as back up so she's not stranded and maybe one of those life alert deals but afraid she may abuse that for any minor emergency. Was away for a weekend once and she called 911 from her phone as it was the only button that worked, I guess to tell them she was left without food. (Doesn't drive) officer came and checked she did have food in the fridge but not what she was in the mood for. He took her out to brunch!
