If you are planning to use an iPhone 18 with a travel eSIM, this page tracks Apple's official eSIM compatibility, SIM configuration and setup information. We will update the same URL as confirmed specifications are released.
Official iPhone 18 eSIM specifications have not yet been published.
iPhone 18 eSIM status
Official iPhone 18 eSIM specifications are still awaiting confirmation from Apple. This section will be updated as soon as Apple publishes the device specifications.
Until then, do not treat rumours, leaks or comparison tables as confirmed iPhone 18 hardware. We will only add eSIM support, physical SIM, Dual SIM, regional differences and setup steps here after Apple publishes them.
What we are waiting for from Apple
When Apple publishes official iPhone 18 specifications, we will update this page with:
- eSIM support
- physical SIM availability
- Dual SIM support
- regional SIM differences
- eSIM installation steps
We will not open a new URL for those updates. The live address stays /blog/iphone-18-esim.
Using a travel eSIM
Travel eSIM compatibility depends on the device's official eSIM support and regional model configuration. Once Apple publishes the iPhone 18 specifications, RoameSIM will update this section with confirmed compatibility details.
On current eSIM iPhones, a travel plan is prepaid mobile data you install from a QR code. Guest checkout on RoameSIM sends the QR by email. You install on Wi-Fi, keep the travel line off until you land, then set that line for mobile data and enable data roaming on it. Full iPhone steps: how to install eSIM on iPhone.
Buy the plan before you travel, keep the QR somewhere you can open without mobile data, and do not delete your home SIM. Those are general travel eSIM habits, not confirmed iPhone 18 features.
Using RoameSIM with iPhone
RoameSIM provides travel eSIM plans for destinations around the world. Once Apple publishes official iPhone 18 eSIM specifications, this guide will include setup notes for RoameSIM users on that device.
You can still shop today for a destination plan and install it on a compatible unlocked iPhone that already supports eSIM:
