All iPhone 14 models in the United States no longer have a physical SIM card slot at all. This means that this year, switching to a new iPhone won't be as simple as removing the SIM card from your old device and plopping it in your shiny new iPhone 14. So how will it work? Well, it will all happen electronically as all US iPhone 14 models now come with dual eSIM support only. An eSIM is a digital SIM that allows a user to activate a cellular plan without having to visit a store or wait for a physical card, it all happens digitally. Keep in mind that it is specifically iPhone 14 models sold in the United States that will not have physical SIM card support, while iPhone 14 devices outside the US still have a traditional SIM tray plus support for one eSIM.

Of course, this comes with a bunch of benefits, but also some potential downsides, so read on to understand all the implications of this switch. We have to also point out that with eSIM, you have all the capabilities of a physical SIM: full access to 4G LTE and 5G carrier networks, same coverage, same everything. Actually, eSIM has been available as an option on iPhones since 2018 when the iPhone XS and XR series first had it, but what changes now is that it is no longer an option, it's the only way.
