The iPhone SE (2nd generation, 2020) and iPhone SE (3rd generation, 2022) both have one. The original iPhone SE from 2016 does not, so check which model you own under Settings > General > About. These SE models work as dual SIM phones with one physical nano-SIM and one eSIM. They can store more than one eSIM profile, but only one eSIM is active at a time alongside your physical SIM. Models sold in mainland China may not include eSIM support, so check yours if you bought it there. ## How it works A travel eSIM arrives by email as a plan your iPhone can download over Wi-Fi. On iOS 17.4 or later, you tap Install on iPhone in the email and follow the prompts, and the plan is added in under a minute. You can also scan a QR code, which is handy for installing from another screen or sharing the eSIM with someone else. Once installed, you choose which line is used for mobile data in Settings > Mobile Service. ## Relevance to travelers With an iPhone SE eSIM you can buy and install a data plan before you fly, so you land online without hunting for a SIM shop or queuing at the airport. Your home number can stay active on the physical SIM for calls and bank verification codes, while the eSIM handles cheap local data. Plans cover 190+ destinations, and prices vary by destination and by each store that sells them. ## Related terms - iPhone SE 2020 - iPhone SE 2022 - Dual SIM - Carrier-unlocked phone - eSIM compatibility ## Example Priya owns an iPhone SE (2022) and is flying from Sydney to Lisbon. A week before the trip she checks that her phone is unlocked, then buys a Portugal eSIM from a creator's store.
