Does anyone know if there is such a thing as a pager that has one push button that will alert my phone?

Not a pager per se, but we bought my mom a Freedom Alert. You program a sequence of numbers for it to call when the button is pressed -- in her case me, my bother and sister. Works great, lets her feel totally secure living alone. One-time purchase, no monthly charges, requires a land line to call out on; the called numbers can be land line or cell, local or LD.

I heard that Walmart carries a home alert system for the elderly.I think it cost around $100.No prescription or monthly charges required.I don't remember the brand name of it.Go to Walmart online and search for it.The system I looked at online wasn't like life alert.It didn't call a service company.I was told the device gives you the opton to program a phone number or 911 to call when the button is pushed.But,it didn't have GPS.I know it was a neckless type device with base.
I was told life alert cost too much money.And half the time elderly people don't remember to push the button.There is a life alert device style out their that has GPS other then life alert but,I don't recall.Search online you will find it.
Best,
