About this app
OpenSim helps you buy and manage prepaid travel eSIM data for international trips. Compare country and regional plans, review the details before you buy, and keep your travel data in one app.
OpenSim was previously known as Roaming eSIM.
CHOOSE DATA FOR YOUR TRIP
• Browse country and regional eSIM plans.
• Compare data allowances, validity and prices.
• View your purchased eSIMs and follow the installation instructions.
• Manage your data and top up plans where supported.
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.
