p.s. There's also handsfree voice dialers.
Handsfree Freedom Voice Dialers and voice activated telephones. They're quite pricey though.

What about the high quality walkie-talkies that are now available? Most of the high quality ones have a long range (some have a range of several miles), and there is no monthly fee involved at all.

Here is a fairly recent article from USA today about the new higher-tech walkie talkies (that are usually called 2-way radios now)-
http://www.usatoday.com/tech/columni...7-kantor_x.htm

My brother (a college student) bought a set of these long range 2-way radios - he kept one for himself and gave the other to his girlfriend so they could talk to each other at any time... these 2-ways have such a long range that they can talk to each other no matter where they are on their college campus (which is quite large). And the units themselves are quite small (although there are other units available that are larger if you prefer a larger unit).

I don't know if these newer walkie-talkies (long range 2-way radios) would work for your situation, but it was the first thing that popped into my head when I saw your post.

Take care,

I was thinking the same too. The walkie talkie /phone things
my kids have used them when they go 4 wheelin and skiing on Mt Hood.

maybe even a small phone with you on the speed dial so she only has to push one button? and it would dial your number for her.

This one that Lara pointed out .... http://www.dynamic-living.com/telemergency.htm

Is a very good unit. We got one for my grandma when I first moved to Napa and it was easy to set up, and more importantly easy to use.

The hardest part about using it, is to replace the batteries on the pendant. They should be checked once a year.
