eSIM compatible phones: how to check yours and set up Zetsim
If you’re searching for “eSIM compatible phones,” you’re usually in one of two situations: you’re about to travel, or you’re trying to add a second line. Either way, the fastest path is not a huge device list. It’s a simple checklist: does your phone support eSIM, and is it carrier-unlocked?
Fast answer: If your phone has an “Add eSIM” / “Add mobile plan” option in settings and it’s unlocked, it’s typically eSIM-compatible for travel.
What “eSIM compatible” actually means
An eSIM is a built-in digital SIM that lets you activate a mobile plan without inserting a physical SIM card. Instead, you add a profile to your phone (commonly by scanning a QR code or using an app).
The part most travelers don’t realize: eSIM compatibility is not only about the phone model. It’s also about whether the phone is carrier-locked. If your phone is carrier-locked, it’s restricted to only support eSIMs from that specific carrier. In that situation, buying a travel eSIM from another provider may not work.
How to check if your phone is eSIM compatible (3 practical methods)
Method 1: Check your settings (the quickest)
Open your phone settings and look for an eSIM option such as Add eSIM, Add mobile plan, or an eSIM section under SIM settings. If the option exists, the device supports eSIM.
Method 2: Confirm the phone is unlocked (the most important for travel)
Many “it doesn’t work” cases come from a locked device. Again: a carrier-locked phone is restricted to only support eSIMs from that carrier. For international travel eSIMs, you generally want an unlocked phone.
Method 3: Verify via manufacturer support pages (the most precise)
If you want a model-by-model confirmation (especially because some features can vary by region), use your device manufacturer’s official support pages. This is the cleanest way to confirm for your exact model.
Do you need an “eSIM supported phones list”?
Lists are helpful, but they go out of date quickly and don’t always capture region differences. A better approach is:
- Confirm the eSIM menu exists in settings
- Confirm your phone is unlocked
- Install on Wi‑Fi so the download completes cleanly
That’s it. If you want a shortcut: if your device is a newer iPhone or a recent Android flagship, there’s a good chance it supports eSIM— but you should still verify the settings and unlock status.

How to activate a Zetsim eSIM (QR setup)
Zetsim’s setup is designed to be done in a few clear steps:
- Step 1: Purchase the eSIM from the Zetsim app/website and receive the eSIM QR code by email or in the app.
- Step 2: Open Settings, tap eSIM, then scan or upload the QR code you received.
- Step 3: After the eSIM is added, select the eSIM network and switch on Data Roaming (as instructed by Zetsim). Land at your destination country and your eSIM will be active.
Is the QR code safe? Using a QR code for eSIM setup is a safe option. The QR code encapsulates setup data and is transmitted securely to your device through secure channels. Zetsim maintains strong security policies designed to protect your data and privacy.

Dual SIM tip: keep your home number and still use travel data
One of the best reasons to use an eSIM is the physical SIM + eSIM combo. You can keep your home SIM active (for OTPs and calls/SMS) while using the Zetsim eSIM for data when traveling.
The key is choosing the correct line for mobile data once you arrive: set data to the eSIM line, not your home line.
Troubleshooting: common issues with eSIM compatible phones
No “Add eSIM” option in settings
- Your model or regional variant may not support eSIM.
- Your phone software may need an update.
eSIM installed but no internet
- Switch Mobile Data to the eSIM line.
- Turn on Data Roaming for the eSIM line (as instructed by Zetsim).
Everything looks right, but activation still fails
- Recheck whether your phone is carrier-locked.
- Confirm you installed the eSIM on stable Wi‑Fi before travel.
If you lose your phone with an active eSIM, contact Zetsim support immediately to disable your eSIM profile to prevent unauthorized use.
