eSIM Profile format from SIM Alliance

Actors in the eSIM arena eSIM.net Support Team

It is not specified what format should be used to deliver the generic profile from an MNO to an SM-DP or SM-DP+ operator or in a SoftSIM/SoC eSIM application.

There are various file formats that can be used to provide the profile e.g. UXP, ASN.1, or even a simple Excel spreadsheet.

The most commonly used format is UXP as specified by the SIM Alliance. This is called the SIM Profile Mark-up Language and is based on XML.

A file of IMSI/Ki pairs must also be generated in order to personalise the generic profile.
