EID Check

Check Description: An EID number is a 32-digit identifier associated with eSIM. Only devices that support eSIM have an EID. This check identifies if a specific IMEI has an EID number, and if so, it indicates the number.

Why It Matters: As eSIM adoption grows globally, knowing whether a device supports eSIM, physical SIM, or both is crucial for global connectivity, carrier provisioning, and future-proofing inventory. – Use version below instead.

Why It Matters: The EID enables accurate activation, lifecycle tracking, and fraud prevention across carriers and marketplaces. It provides a trusted anchor for verifying device authenticity, managing ownership, and ensuring clean, compliant transactions in eSIM mobile ecosystems.

When to Use: This data is especially useful for those planning to do OTA (over the air) activations. Knowing the EID number is crucial to perform OTA activations. Lack of an EID can mean that the device only has physical SIM capabilities, requiring a different reactivation protocol.
