I started with a flip phone
Now I finally have a smartphone. I use it's calendar to help me schedule all my doctors visits and for my emails. Other than that I don't use it much more than I did my flip phone for phone calls. Until I got the smartphone I had a prepaid account and each time I used it the time came off my prepaid account. I think I paid about $10/month and it was only used for emergencies at first. I took it with me when I went out fishing by myself. If I needed help I'd take it out and call for help. Never really used it to call for help. I must have had this flip phone for ten years.
Finally in 2016 I broke down and decided to buy a Samsung Galaxy Note 4. It was on sale as it was a few years old but still a great phone. Now I use it to text and make phone calls as have an monthly account with unlimited calling and text. I use the calendar and the email (Outlook) app. I send instant messages to my friends and family and even my Doctors. I have email portals with most all my doctors so I can keep in contact with them. I can read the medical reports. I even carry a phone charger in my pant's pocket.
About 4 months ago I stubbed my big toe and had to go to the ER to get the toenail taken off. I could not go back into the house as my toe was bleeding badly. So I asked the EMT lady if she would go get my phone charger out of my pants pocket which were back in the house. She came back out onto the back deck where I had retreated so as not to bleed any more on the kitchen floor. She said should could not find the charger. The 5.11 tactical pants that I had the phone charger in have many pockets and I guess she was afraid to go though all the pockets. When I got home later that nigh via a taxi ride home I found the charger right were I said it was. So when I went to the ER without my phone charger I knew that I had to conserve battery power or I'd be left without a cell phone. Luckily my cell phone has a way to turn off all but the essential apps to save battery power. I could have gone for 5 more days on the low power setting. So I was able to make calls during the 4 hours I waited to see the ER doctor. He had much more important emergencies to attend to other than numbing up my big toe and taking the nail off with his pliers. He had to cauterize the nail bed with chemicals to stop the bleeding 5 hours after I stubbed the toe at the back door of my kitchen. There were three big pools of bright red blood on the kitchen floor that the nice EMT lady cleaned up for me with some paper towels or something. As when I go back home the floor was clean and the blood was gone.
But though all this and all the pain I was still wishing that I had my phone charger with me in the ER.
Normally if I'm out eating or waiting in the lobby of my doctor's office I can read the news on my smartphone. I need my reading glasses to do that but I carry them with me all the time just as I do my smart phone. I don't know how I did without it.
Several things go with me when I leave the house. My gun, my smartphone, my charger and my eyeglasses along with the regular things that everyone takes with them like your wallet and keys and change.
When I was in High School we didn't have cell phones. We used the pay phone to call for a ride home. And we wore penny loafers where I stuck a quarter or a nickel in them to make the pay phone call home for a ride after tennis practice or track practice. We moved up to CB radios later in life. Then while working one day a coworker gave us the BRICK to make calls. Yea I use the first portable phone made commercially for retail sale. The Motorola Cell Phone that was the size of a brick. From there they changed the size and shape of cell phones. Now we have two camera, sound recording and well as video play back. Now we have commercials to watch on our YouTube Videos.
