After activation, we send you a personal Transparency Link where you can check your real-time data usage, remaining balance, and plan validity anytime. No need to dig through phone settings - just tap the link.

EsimGlobal Top-Up lets you add more data to your existing eSIM without buying a new plan. When your data runs low, we send you a top-up link. Just tap it, choose your data package, and continue browsing - no reinstallation needed.

You get connected before you land - no hunting for SIM shops at the airport. Activation takes seconds with our direct activation link, you keep your home number on your physical SIM, and you avoid expensive roaming charges from your home carrier.

Try the activation link instead - just tap it directly from your email. If you must use the QR code, ensure you're scanning from a screen with full brightness. You can also enter the activation details manually.

Enable the eSIM in your settings, turn on Data Roaming for that eSIM, and make sure it's set as your data line. Your phone will connect to the local network automatically. Check product details for your plan's specific activation behavior.

Most flagship Android phones from 2019 onwards support eSIM, including Samsung Galaxy S20+, Google Pixel 3+, Huawei P40+, and many Xiaomi, Oppo, and OnePlus models. Check your phone's specifications to confirm.
