Apple will offer SIM-free iPhone XS and iPhone XS models for pre-order according to Apple's website, which means customers will be able to purchase the new smartphones without a carrier.

The SIM-free models are not always offered for newly launched iPhones, especially when supplies are tight, so the availability of SIM-free models suggests iPhone XS and iPhone XS Max supply will be plentiful this year.

SIM-free models are unlocked and can be activated with any carrier at a later date, making them an appealing purchase choice.

To purchase a SIM-free device, the outright price must be paid upfront. The iPhone XS starts at $999, while the iPhone XS Plus starts at $1,099. Apple plans to begin offering pre-orders this Friday, likely at 12:01 a.m. Pacific Time based on past iPhone launches.
