eSIM

eSIM (Embedded SIM) is a programmable chip embedded within a device. Users can activate or switch network services by remotely downloading carrier profiles — without replacing a physical SIM card.

Compared to traditional SIM cards, eSIM technology:

• Eliminates the need for logistics and physical delivery.

• Supports storing multiple carrier profiles on one device.

• Allows switching between networks at any time with ease.

Based on this technology, RoamFi provides cross-border data services across multiple global regions, making international connectivity more convenient and flexible.

Currently, RoamFi’s eSIM service focuses exclusively on mobile data access, featuring the following characteristics:

• Data-only service: Voice calls and phone numbers are not included.

• No KYC required (Know Your Customer): Users can register using only an email address, ensuring privacy protection and a low entry barrier.

• No network restrictions: Users can freely access global internet resources for an open and flexible browsing experience.
