Old Man Going I-Phone ------ Advice Please

I'm old also and finally parted with my flip phone reluctantly 6 mos ago. My old phone was $30/mo with 450 min talk. The I phone 5C was free and cost $40/mo. I got the Iphone only because my kids had it and could show me how to use it. Besides having unlimited talk and text when I signed up with the family plan they double my sil gigs from 15 to 30 so for me when I travel it is great I never run out of data. I downloaded Copilot and saved $400 over a RV specific GPS. It is also a hotspot for my laptop, a camera both video and still, an alarm clock, trip planner, has traffic updates, and weather alerts. With the 8 gigs of storage I download pictures to my laptop which is not a problem( I haven't figured out how to use I cloud yet). There are many more features that I don't use now but may use someday as I learn about the phone. My wife says I don't like change but this was a good one.
