Before you buy a travel eSIM, make sure your phone supports eSIM and isn't locked to your carrier. Both take a minute to check. Here's how on iPhone and Android, plus what eSIM-only iPhones mean for travelers.

iPhone

XS, XR and newer support eSIM. That includes the iPhone SE (2nd and 3rd generation). According to Apple, US iPhone 14 and later models are eSIM-only, with no SIM tray. The iPhone 17, 17 Pro and 17 Pro Max are eSIM-only when bought in several countries, including the US, Canada, Japan, Mexico, Saudi Arabia and the UAE, and the iPhone Air is eSIM-only everywhere.

How to check on iPhone

1. Open Settings, then Cellular (or Mobile Data).
2. If you see "Add eSIM" or "Add Cellular Plan," your iPhone supports eSIM.
3. Settings, General, About also shows an EID entry on eSIM-capable models.

Android

Many recent Pixel and Samsung Galaxy models support eSIM. Check Settings, then Network. Support depends on the model and sometimes the country or carrier version of the phone.

How to check on Android

1. Open Settings, then Network & internet (or Connections), then SIMs or SIM manager.
2. Look for "Add eSIM," "Download a SIM instead" or similar.
3. Or check Settings, About phone, for an EID number.
4. If unsure, search your exact model number on the manufacturer's site.

Unlock status

Your phone must be unlocked to use a travel eSIM from a different provider.

• iPhone: on iPhone, "No SIM restrictions" under Settings, General, About, Carrier Lock means it's unlocked.
• Android: look under Settings, About phone, or SIM status, or insert another carrier's SIM. Menu wording varies by maker.
• Still locked? Contact your carrier. In the US, carriers have unlocking policies that typically require the device to be paid off and active for a period of time.

Compatibility at a glance

How many eSIMs can you store?

Phones can store several eSIMs, though usually only one or two can be active at the same time. You can keep a travel eSIM installed between trips and switch it on when needed. Delete old ones you'll never reuse to avoid confusion.

What if my phone doesn't support eSIM?

• Buy a local physical SIM on arrival, if your phone is unlocked. See eSIM vs roaming vs local SIM.
• Use your carrier's international plan or day pass.
• Use a pocket Wi-Fi hotspot device.
• Rely on Wi-Fi, with offline maps downloaded in advance.

Before you buy a travel eSIM

1. Confirm eSIM support and unlock status.
2. Check the plan covers your destination and the networks there.
3. Note whether the eSIM can be reinstalled if you delete it. Many can't.
4. Plan to install it on Wi-Fi before you leave. See how to set up a travel eSIM.

Travel tips for eSIM-only phones

If your iPhone has no SIM tray, you can't use a physical local SIM, so a travel eSIM or your carrier's international plan is the way to go. Many local carriers abroad now sell eSIMs too, often in their stores or apps. Keep a screenshot of your eSIM's activation details in case you need support.

Phones bought abroad or from carriers

A phone's eSIM support can depend on where it was sold. Some models sold in mainland China, Hong Kong or Macao, for example, have historically used dual physical SIMs instead of eSIM, and some carrier-branded Android phones ship with eSIM disabled. If you bought your phone secondhand or overseas, check the exact model number in Settings, About, and look it up on the manufacturer's support site. If a carrier sold you the phone on installments, it may stay locked until it's paid off, even if the hardware supports eSIM. Sort out unlocking a few weeks before you travel, since carrier unlock requests can take time to process.
