Covering major brands and models (and what travelers should check before they fly)
eSIM technology has moved from “nice-to-have” to “standard feature” on modern smartphones, especially for travelers.
If you’re planning to use a travel eSIM, the first question is simple:
Does your phone support eSIM?
This guide covers which iPhones and Android devices support eSIM, how to confirm compatibility in seconds,
and what to watch for with regional variants and carrier restrictions. If you’re traveling soon, you’ll also find setup tips
to help you connect quickly with a OneSimCard eSIM.
Quick jump:
What Is eSIM and Why Compatibility Matters
An eSIM (embedded SIM) is a digital SIM built into your phone’s hardware. Instead of inserting a plastic SIM card,
you download a mobile plan using a QR code or activation link. For travelers, this means faster setup, easier switching between plans,
and no fragile SIM trays to deal with at 2 a.m. in an airport.
Compatibility matters because not every phone supports eSIM, and some models support it only in certain countries or carrier versions.
Confirming compatibility before purchase avoids the most common travel connectivity headache: “I bought a plan… but my phone can’t install it.”
Quick Comparison Table (At-a-Glance)

|---|---|---|
| iPhone (XS/XR and newer) | Yes on modern models | U.S. iPhone 14+ are eSIM-only. Most newer iPhones support dual SIM (physical + eSIM or dual eSIM). |
| Samsung Galaxy (S20+ and newer; Z Flip/Fold) | Usually yes | Some carrier-locked or regional variants may disable eSIM. Unlocked models are best for travel. |
| Google Pixel (Pixel 4 and newer) | Yes | Pixels are among the most travel-friendly for eSIM. Great for switching plans and quick activation. |
| Other Android brands (Motorola/Sony/Xiaomi/OPPO/Honor) | Model & region dependent | Check Settings for “Add eSIM” and verify your exact model variant (some regions omit eSIM). |
