A travel eSIM is a digital SIM with a prepaid data plan for another country. It works on an unlocked phone such as an iPhone XS or later or a recent Google Pixel, and installs with a QR code or app.

Key takeaways

  • A travel eSIM is a prepaid data plan you install with a QR code, no SIM card needed.
  • Your phone must support eSIM and be unlocked (iPhone XS/XR or later, recent Pixel).
  • Install it at home on Wi-Fi, then switch cellular data to the travel line on arrival.
  • Most travel eSIMs are data-only; keep your home line for texts if you need them.

Quick answer

Quick answer

What is an eSIM?

An eSIM is a SIM built into the phone. Instead of inserting a plastic card, you download a carrier profile, usually by scanning a QR code or through the provider’s app. A travel eSIM is a prepaid data plan for one country, a region or worldwide use.

Before you buy: requirements

  • Compatible phone: Apple says iPhone eSIM travel use needs an iPhone XS, XS Max, XR or later. Many recent Android phones, including Google Pixel models, also support eSIM.
  • Unlocked phone: on iPhone, go to Settings > General > About and check that “No SIM Restrictions” appears next to Network Provider Lock.
  • Internet connection to download the eSIM (Wi-Fi or hotspot), in most cases.
  • ID: some providers ask for a passport to activate.
  • Mainland China: Apple notes that only specific newer iPhone models support eSIM there; check before you travel.

How to install a travel eSIM on iPhone

  1. Buy a prepaid data plan from a worldwide or local provider (before the trip or after you arrive).
  2. Activate it the way the provider explains, usually by scanning a QR code or using its app.
  3. On arrival, if you see “Turn On Travel eSIM” (iOS 26 and later), tap it and choose whether to keep your home line on too.
  4. To choose the data line manually, go to Settings > Cellular (Mobile Data) > Cellular Data and select the travel eSIM. Your home line can still handle iMessage and FaceTime.
  5. Back home, iPhone should switch back automatically; if not, go to Settings > Cellular, turn your main line on and turn off the travel line.

How to install a travel eSIM on Google Pixel

  1. Open Settings.
  2. Go to Network & internet > SIMs > Add SIM > Set up an eSIM.
  3. Follow the on-screen steps (scan the QR code or use the details from your provider).
  4. If the eSIM isn’t detected, contact the provider with your phone’s IMEI.

On other Android brands, the menu names vary (look for SIM manager or SIMs in Settings). Check your manufacturer’s support page.

Tips to avoid surprise charges

  • Turn off data roaming on your home line if your carrier charges for it, and keep it on for the travel eSIM if the provider asks.
  • Install the eSIM at home on Wi-Fi, but activate the plan only when you arrive if its validity starts on first use.
  • Keep the QR code until the trip ends; some eSIMs can’t be reinstalled once deleted.
  • Check whether the plan includes hotspot use and calls, or data only.

Frequently asked questions

Can I keep my normal number while using a travel eSIM?

Yes, on phones with Dual SIM support. You can keep your home line active for calls, texts or iMessage while the travel eSIM handles data, but your home carrier may charge roaming for activity on that line.

Which iPhone models support travel eSIMs?

Apple lists iPhone XS, XS Max, XR and later. The phone must be unlocked; check Settings > General > About for “No SIM Restrictions”.

When should I install a travel eSIM?

Installing before you leave, on Wi-Fi, is easiest. Many plans start counting days only when they first connect at the destination, but check your provider’s rules.

Does a travel eSIM include calls and texts?

Most travel eSIMs are data-only. You can still use internet calling apps. Some providers sell plans with a local number.
