Frequently Asked Questions (FAQs)
Find quick answers to the most common questions about eSIMs and our service.
An eSIM (embedded Subscriber Identity Module) is a digital SIM card that allows you to activate a cellular plan from a carrier without needing a physical SIM card. It is built into your phone or device, making it much more convenient for travelers to switch network providers globally.
Most modern smartphones, especially models released after 2018, support eSIM. This includes iPhone XS/XR and newer, Samsung Galaxy S20 and newer, Google Pixel 3 and newer, and many modern tablets and smartwatches. Please check our detailed compatibility list on the website to confirm your device.
After purchase, you will receive an email with a QR code. To activate: Go to your phone’s Settings > Cellular/Mobile Data > Add Data Plan/eSIM. Scan the QR code, label your new plan, and follow the on-screen prompts. Ensure you are connected to Wi-Fi during the installation process.
Yes, absolutely! One of the biggest advantages of eSIMs is dual SIM functionality. You can keep your physical SIM card active for calls and texts (if required) while using the eSIM for mobile data abroad. Just make sure to set the eSIM as the primary line for cellular data.
For most of our plans, the validity period (e.g., 7 days) starts immediately upon **connecting to a supported network** in the destination country. For some specific plans, it may start upon installation. Always check the plan details provided in your confirmation email.
If your data runs out, the eSIM will simply stop connecting to the internet. You can easily purchase a **Top-Up** package directly on our website and instantly apply it to your existing eSIM profile without needing to install a new QR code.
