## What is OpenSim?

OpenSim: Roaming eSIM & Data helps you buy prepaid mobile data for your next trip. Choose a roaming eSIM plan for one country or a whole region, buy it in the app, and manage your eSIM and data in one place, instead of swapping SIM cards or paying your home carrier's roaming rates for data.

OpenSim was previously known as Roaming eSIM: same app, same team, new name.

CHOOSE DATA FOR YOUR TRIP
• Buy roaming eSIM data plans for countries and regions.
• Compare data, price per GB and network speed before you buy.
• Choose your trip length on unlimited plans where available.
• View your purchased eSIMs and follow the installation instructions.
• Manage your data and top up plans where supported.
• Give an eSIM gift card, or refer friends and earn store credit.

GET STARTED
1. Check that your device supports eSIM and is carrier-unlocked.
2. Choose a plan for your destination and travel dates.
3. Review its coverage, included services and activation rules before payment.
4. Follow the plan's installation instructions while you have an internet connection.
5. Select your travel eSIM for mobile data and follow the connection guidance for your destination.

KNOW BEFORE YOU TRAVEL
Activation rules vary by plan. Depending on the plan, validity may begin at purchase, installation or the first connection to a supported network. Check the activation terms before you buy or install.

Top-ups are available only for supported plans. Coverage, network availability and speeds depend on the destination, plan and device.

If you keep your home SIM active, your home carrier may still charge for calls, texts or data. Check your phone's SIM and roaming settings before you travel.

Use your travel data for maps, messaging, internet calls, transport apps and other online services.
