The new Apple ESIM card allows you to switch between AT&T, T-Mobile, Verizon and other carriers, where the regular SIM card in most older iPhones only allows one carrier at a time.

Apple’s new iPhones have two SIM cards – one a physical card and an ESIM. An ESIM is handy for travelers going out of the country, and the Apple Watch, Samsung’s Galaxy Watch, some iPads and the Surface Pro have ESIM capabilities.

People are still confused about the difference between iCloud and iCloud Drive. iCloud mostly serves to back up your iPhone or iPad and sync limited kinds of data to other Apple devices, while iCloud Drive more focuses on sharing among all your devices. This means that data in one device can be shared among other devices without copying, sending or transferring.

If you ever lost data and Apple can’t help you recover pictures, notes or e-mails, there is an app called iMyFone D-Back iCloud Backup Viewer and Extractor. This app or program will recover all your lost data.

There is a new security feature on the iPhone and iPads called “key-based protection,” which is a key that connects to the USB-C, USB-A or lighting port. This key is like a password or Touch ID or Facial ID to open up your iPhone and buy items on the Internet using Safari.

More on this later as people start to use it and comment on how it works. For now, just keep a list of your current passwords.

Wouldn’t you like to read website articles on Safari without viewing all the ads covering most of the page? Well, now you can – it’s called Reader View. To activate it, open up Safari and click on an article that you want to read. A symbol with three lines appears in the address bar above. Just click on the three lines and only text is displayed.

But the best part is now you’re able to increase the font size, color or type of fonts by clicking on the “aA” symbol on the right side of the address bar. You can also use the shortcut keys Shift, Command, R. Firefox also has a reader view located to the right on the address bar that looks like a square box. Your iPhone’s Safari app also has reader view on it.

Ok, are you ready for the future? NFC means Near Field Communication. So? Big deal!! Well, hold on to your pants. These are little tags that you can buy on the Internet that come in bundles of 6-10. They can look like two- inch squares of paper that have tiny electronics built inside of them. So, what can you do with them? By holding your iPhone up to them, you can read what you programed to them with text and data.

Are you falling asleep? Let me give you an example that any store or home owner could use them for.

Let’s say your coffee store has a Wi-Fi router password that you need to get. Interrupting the barista making an almond milk, double-shot latte and giving you stink eye, he yells it out, spilling milk all over the floor. But if they had a posted sign telling you to touch your iPhone to the NFC sticker glued on it, you could have automatically received the password.

Good coffee? Let’s say you want to buy a bag of coffee off the shelf. Touching your iPhone to the NFC sticker, you’ll see how much it costs and get a little information on it… so you don’t end up buying Folger’s Instant Crystals.

Just touching your iPhone to any tag gives you a variety of things to see. Shop owners could put tags on all their merchandise, and even Sargent’s Fine Art gallery could put NFC tags on all their paintings with not only the price tag but information about the artist and the paining.

You can have one on the front door, and when your iPhone touches it, the tag will automatically turn the house lights on.

One of the best apps on the App Store is NFC Tools. This is the future, so get with it!
