Have Any Questions!
An eSIM (embedded SIM) is a digital SIM built into your device. It works by downloading a mobile plan directly to your phone or tablet via QR code—no physical SIM card needed. It lets you connect to mobile networks instantly and manage multiple plans with ease.
Most newer smartphones support eSIM, including iPhones (XR and later), Google Pixel phones, and recent Samsung Galaxy models. You can check in your device settings under Mobile Networks or consult your manufacturer's website for compatibility.
Yes, most eSIM-compatible devices support dual SIM functionality. This means you can keep your regular SIM for calls and use the eSIM for data while traveling or working abroad.
After purchasing a plan, you’ll receive a QR code and activation instructions via email. Simply go to your phone’s settings, tap “Add eSIM” or “Add Mobile Plan,” scan the code, and you’ll be connected within minutes.
