Thanks for the input, folks. I'll keep searching. I may find a card/plan where the minutes don't expire. That's been one of the toughest challenges along with sifting through the sheer volume of plans/cards available.
With this little lady, I would be the one entering in any access numbers and then handing her the phone, so she's covered in that respect. She lives very close to me, and I see her quite a bit.
She only needs long distance to return calls (max of 2, if they call) that she misses at Thanksgiving/Christmas when she is at someone else's house. If she is at home when the calls come through, then she answers the phone, talks, and is done with long distance for another year.
I'm of little help to her because I use computer/email, but I will try to find something for her where it's not a use it/lose it proposition.
I did a little research on using something like Tracfone, but I need to see what the deal is about possibly losing your phone number if you let your minutes expire.
Again, thanks for the input.
