New to travel eSIMs? These answers cover the basics — what an eSIM is, how RoameoGo works and what to check before you buy.
An eSIM is a digital SIM that lets you connect to mobile data without inserting a physical SIM card. With RoameoGo, you can buy a travel eSIM online, receive setup details by email and connect when you travel, subject to device compatibility and network availability.
Read our full beginner's guide — What Is an eSIM and How Does It Work? — in the RoameoGo Travel Guides section.
Choose your destination, select an eSIM plan and complete checkout. Your eSIM setup details are usually delivered by email shortly after purchase. Follow the installation instructions to set up your eSIM on your device.
Before you buy:
Most eSIM-compatible devices support running both a physical SIM and an eSIM at the same time. This means you can keep your home number active for calls while using your RoameoGo eSIM for data.
Your home carrier may still apply roaming charges if you use your regular SIM to make or receive calls abroad. Check your home plan's roaming terms before travelling.
