The iPhone 14 was an eSIM-only phone in the U.S. Most people who plan to buy one will just have their phone carrier set them up. They don't worry about what will happen if they go abroad for a job or play.

I am not a typical person. You're probably not part of that group because you're reading a website on your phone. There is a lot to discuss when it comes to Apple moving away from the tiny plastic sim card.

The idea of the eSIM is appealing to me. I use the eSIM as the primary on my phone, with a T-Mobile sim card as a backup if I need more data or tethering. I don't like the idea of having a phone that doesn't have a sim card. Maybe in a few years, but not yet. I don't have to worry about it because I don't have a plan to buy an Apple product.

What is an eSIM?

The interface between your phone and your carrier is called an eSim. It's basically the same as a "regular" sim card, except it uses a chip inside the phone to hold all the data, instead of a chip inside the phone to read and write it.

Your country of origin, your carrier, and a unique user ID are all contained in an eSIM. The phone company can bill you and identify you on the network.

Your phone isn't going to work on any carrier network if you don't have a sim card.

The first eSIM-only phone that would be released in 2020 would be the re-release of the Moto R. The pros and cons of not having a standard sim card is shared.

The best thing about the eSIM is not that it's easy, it's that it is. It's not hard to not put a small piece of plastic in a tray. One of the worst things about the eSIM is its security.

Using an eSIM can be a good experience.

It is more difficult for someone to get control of your phone number if you have an e sim. You have to visit a store if you have an eSIM option from a carrier.

It's easy to switch carriers to avoid roaming fees with an eSIM. An eSIM service that switches between carriers based on location but keeps the same number is pretty cool.

It's easier to not have to find a paperclip to open a tray. I just open an app and use a button to set things up, for example, if I use Google Fi it won't work on the iPhone 14. It's a good thing that I don't have to go to a store to use a scanning device.

What's not so good about an eSIM?

There are a lot of small issues with the eSIM that can be solved by Apple and the internet. Both companies are figuring out how to support and store multiple lines. Some problems can't be fixed by companies I trust.

There is a security issue. There are multiple security exploits waiting for someone to find in the eSIM module of the iPhones. You can't get rid of all the issues with software. There is a new way for bad actors to try and take control of your life.

Major carriers in the U.S. offer eSIM options. Smaller regional carriers may be forced to build support for the Apple device. You have limited options outside of the west if you have an eSIM only phone.

I like to travel to Costa Rica for vacations. If I had an eSIM-only phone in Costa Rica, I would have to use a third-party service to keep my credit card information safe. We all know that small companies have good online security.

An "iSIM" is a terrible idea for everyone except Apple.

Control is the biggest issue. The company that made your phone, the company that wrote the software, and the phone companies themselves decide if you can have service or not. If you pay for it, you can have it, and if you don't, you can't.

That could be a bigger problem for the Apple community. Apple is rumored to want to build an "iSIM" in a future version of its phone chips so it has complete control over everything.

That's correct. Once Apple gets everything sorted out, an iSIM could be used in the Macbook, the iPad, and the Apple Watch. That is positive for Apple. It's not good for Apple customers who finance their products through the company.

If you were dumb enough to try it, it would be hard to get out of iMessage. Imagine how difficult it would be to keep your phone number.

Eventually, the industry will be able to only use eSIMs. Since the release of the first phone with an eSIM, this isn't an Apple phenomenon. Apple and Microsoft added support for their products. This is where the industry is going.

The fact that the iPhone 14 is only launching in the US highlights some of the bigger issues that need to be sorted out. It would be a mistake for other phone companies to follow Apple's lead and not fully bake the tech. The best phones on the market use a regular sim card.

The plastic card is small. It just needs to live long enough to know its replacement is ready.
