iPhone X

  • Apple started offering a new SIM-free unlocked iPhone X as of Monday that works with any carrier.
  • It’s similar, if not equal, to the Verizon and Sprint iPhone X model, which also lets you use any carrier you want, including AT&T and T-Mobile.
  • AT&T and T-Mobile iPhone X models aren’t compatible with Verizon or Sprint’s networks.
  • AT&T and T-Mobile customers should buy the Verizon model with the iPhone Upgrade Program, or the SIM-free unlocked model if they want the most flexibility of changing carriers.

Without fanfare, Apple started offering the unlocked, SIM-free model of the iPhone X on Monday, which can work on “any carrier that provides service to iPhone,” as Apple puts it.

A SIM card is the tiny chip inside smartphones that allows wireless carriers to identify and authenticate the device on their networks. Many people take their SIM card with them when they upgrade phones, inserting their old SIM card into their new device. For those that travel or work in other countries, it’s also possible to swap in a SIM card from a local wireless carrier instead of opting for an international smartphone plan.

When you buy a SIM-free unlocked iPhone X, you’re free to insert a SIM card for any US carrier, and it’ll even work with foreign SIM cards in other countries that support the iPhone, too. It’s perfect for those who want the flexibility to switch to any carrier of their choice.

The SIM-free unlocked iPhone X technically works more like the existing Verizon and Sprint models, which are compatible with Verizon and Sprint’s CDMA network, as well as GSM networks like AT&T, T-Mobile, and many other carriers around the world. With that in mind, AT&T and T-Mobile customers should opt for the Verizon model if they’re buying it with the Apple iPhone Upgrade Program, or Read More Here
