AT&T, Sprint, T-Mobile, and Verizon Wireless are the national wireless carriers for iPhone in the United States. Apple.com and the Apple Store sell iPhone models for use on these networks. You can also purchase iPhone from an authorized Apple reseller.
All iPhone models are world phones, so you can use them almost anywhere. Whether you are a GSM or CDMA network customer, you can roam internationally on GSM networks in over 200 countries around the world. Availability of LTE data varies in some countries and depends on carrier support for certain LTE radio frequencies. Contact your wireless carrier for more information regarding international roaming policies and rates.
