A cell phone question.

[LAS14]

Once again I turn to the smart people in this group even though my question isn't about "computers." Well... I guess these days a phone is a computer.

I have a Verizon flip phone and recently bought a no-contract Tracfone to use when hubby and I go on a trip. The new phone works fine, but I'm puzzled by the fact that in the Call list I see at the top "Primary Cell" and my original phone's cell number.

How does my new phone know about my original phone? And vice versa, I see now. Maybe I gave that info during the setup? Googling all forms of "Tracfone primary cell" is no help.

Is there a benefit to having the phones know about each other?

1. SIM Card?

2. Could you explain a little more? How do the sim...

... cards know about each other?

3. Did you use the SIM from your old phone?

I think some historical data is stored there. Otherwise unless something is tied to your number I have no clue.

4. No. My old phone is still operational. We now have two phones that...

... we can use to contact each other while we're on vacation.

5. you got me here.

I'm not sure how it would do that. Sorry I wasn't any help.
