U.S. carriers like Verizon, AT&T, T-Mobile and Sprint are concerned that a recent report from Dow Jones is true. The word is that the 2018 Apple iPhone models will replace the tradition SIM card and SIM tray for an embedded eSIM chip. If this does occur, iPhone users will have a lot of flexibility when it comes to cellular connectivity. Unlike a SIM card, which is obtained from the user's wireless provider and must be inserted in a phone for it to connect to that provider's network, an eSIM is programmed OTA.
Apple’s 2018 iPhone X could be a big headache for mobile carriers
As excited as consumers might be for the next iPhone, mobile carriers might be in for a nasty surprise. As Barron's notes, Apple might debut an eSIM chip in its next iPhone models. If you've ever switched cell carriers (or have even a passing knowledge of smartphones), you've probably heard of SIM cards. These plastic cards fit into a tray that slides into your phone and allow cell towers to identify your phone. Without one, you can't get service.
