eSIM Service

The eSIM service is a new form of SIM card that is embedded into the device or equipment, rather than being in the form of a traditional physical card with a chip. It allows making calls, receiving calls, and using the internet just like a traditional SIM card. Additionally, it can be used on current networks, both for postpaid and prepaid packages.

eSIM Benefits

No need to hassle with opening trays to insert SIM cards

or swapping SIM cards if you want to use another number.

No worries about losing SIM cards

because they are embedded in the device.

Multiple eSIMs can be used in a single device,

supporting up to 8 phone numbers.
