What is an eSIM and how does it work?

Answer: An eSIM (embedded SIM) is a digital version of the traditional physical SIM card. The chip is already built inside your phone, so you don't need to fumble with tiny plastic cards or pins anymore.

How does it work? It works just like a digital download. When you purchase a plan from Cellesim, you receive a QR code via email instantly. Scanning this code in your phone’s settings installs a "digital data profile" that connects you to local mobile networks abroad.

The Key Benefit: It enables Dual SIM functionality. You can use Cellesim for affordable high-speed data while keeping your primary home number active to receive urgent calls and SMS verification codes (like bank OTPs).
