Not only do we not have to worry so much about long distance phone calls since we have unlimited talk and text, there are also the apps that a person can use and make video calls to just about anywhere for free, as long as you have home WiFi or cell service.
We use iMessage for texting, and Facetime for both audio and video calls, and this works even with my daughter who is working in the Netherlands.
All we have to be concerned with is the time difference, but we can talk for hours if we want to do that.
I am one of those seniors that just LOVES technology, at least for the most part. It has really opened up my life to be able to be in contact with my family and friends, not to mention being able to search for anything online now.
