eSIM stands for embedded SIM. Unlike a removable plastic SIM card, an eSIM is a small chip permanently built into your device. You add mobile plans to it digitally — by scanning a QR code or entering a code manually — without inserting anything physically.
eSIM support is now available in a wide range of smartphones, tablets, smartwatches and laptops. Most flagship devices released in recent years include eSIM capability, though support varies by manufacturer, model and carrier region.
When you purchase a travel eSIM from RoameoGo, you receive a QR code or activation code by email shortly after checkout. You go into your phone’s settings, scan the QR code and download the mobile profile. Once installed, the eSIM connects to local networks at your destination.
The main practical difference is convenience. There is no card to buy at an airport kiosk, no risk of losing your home SIM during the swap, and no SIM tray to fiddle with. Most compatible devices support running a physical SIM and an eSIM at the same time, letting you keep your home number active for calls while using local data abroad.
Because an eSIM is digital, you cannot feel whether it is installed. Always check your phone's SIM or cellular settings to confirm the eSIM profile is showing before you travel.
Traditional roaming connects you abroad through agreements between your home carrier and overseas networks. This can be convenient but may result in higher costs, depending on your provider, plan and destination. A prepaid travel eSIM offers a fixed data allowance at a set price, making costs predictable. Coverage and speeds will vary based on the networks available in your destination.
Some home carriers include international roaming in their plans at no extra cost. If you are only travelling for a very short trip, it may be worth checking with your provider before purchasing a separate eSIM.

Make sure you have:
Most eSIM-compatible devices support dual SIM — a physical SIM and an eSIM simultaneously. This lets you keep your home number active while using the eSIM for data abroad. Check your device’s SIM settings to confirm.
This depends on the specific product. Some eSIM plans allow the profile to be reissued to a replacement device, while others are single-use. Contact RoameoGo if you need help with a lost device.
Yes — you need a Wi-Fi connection to download and install the eSIM profile. Once installed, the eSIM connects to mobile networks and Wi-Fi is no longer needed for normal use.
