I'm scared to do this: any thoughts?

[Paper Roses]

My kids have put me on their cell plan and given me a phone with far more functions than I need. I want only to send and receive.

That aside:

I have had my current land line for 45 years. I have no idea how many people or businesses have the number but certainly some are important but I have no idea who other than my bank, insurance company etc.

The last 2 months, I have tried to use the cell phone for long distance as often as possible. Takes some getting used to.
Yesterday I paid my normal bills and one of them was to Verizon. OK, this was a 2 month bill.
April $8.00 worth of toll calls (one town over) , May-$12.00 the rest of the bill are fees, taxes and other junk.
Grand total 92.06
I live on SS and must cut all corners. It seems that this is one of them.
Have you ever been nervous about closing your land line and going cellular?

When I am upstairs, I cannot hear the phone ring. That bothers me. I wish there was a remote ring station. I could still go downstairs if I could hear the phone.

If I am home, I am usually on the first floor and can answer, otherwise I
am out of luck.
I feel funny having to rely on a cell phone.
Any thoughts?
