This API checks whether a mobile device supports eSIM based on a submitted IMEI number. It is designed for use cases that require eSIM compatibility lookup, device onboarding, mobile plan eligibility checks, and telecom workflow automation.
Developers can submit a single valid IMEI number and receive available eSIM compatibility information in a structured JSON response.
Submit a valid 15 digit IMEI number to retrieve available eSIM support information for the device. The endpoint uses a simple REST request and returns JSON data that can be used in eligibility, activation, support, and inventory workflows.
| Field | Description | Example |
|---|---|---|
| imei_number | IMEI number used for the eSIM compatibility lookup | 350964814514439 |
| esim_compatibility | Indicates whether the device supports eSIM | true |
| number_of_sim_cards | Number of SIM cards supported by the device when available | 2 |
| created_at | Timestamp of the generated result | 2026-06-11 10:43 UTC |
This listing focuses on checking eSIM compatibility from an IMEI number. Additional device verification services may be available as separate APIs, depending on business requirements and data availability.
This API currently focuses on eSIM compatibility lookup from an IMEI number. It returns eSIM support information and the number of SIM cards when available. It does not include blacklist status, carrier lock, iCloud lock, Google FRP, warranty, stolen-device checks, ownership verification, or mobile plan activation.
The eSIM Check endpoint returns structured data regarding eSIM compatibility based on the provided IMEI number. This includes fields such as the IMEI number, eSIM compatibility status, the number of SIM cards supported, and a timestamp of the result.
The key fields in the response data include `imei_number` (the IMEI used), `esim_compatibility` (true or false), `number_of_sim_cards` (how many SIMs the device supports), and `created_at` (timestamp of the result).
The response data is organized in a JSON format, with a main object containing metadata and a nested `result` object that holds the specific eSIM compatibility information, making it easy to parse and utilize.
The eSIM Check endpoint provides information on whether a device supports eSIM, the number of SIM cards it can accommodate, and the IMEI number used for the lookup, enabling effective device compatibility assessments.
Data accuracy is maintained through IMEI.info's extensive device datasets, which are regularly updated and verified. This ensures that the eSIM compatibility information is reliable and reflects the latest device specifications.
Typical use cases include telecom operators verifying device compatibility for eSIM activation, e-commerce platforms checking devices before selling eSIM plans, and repair shops assessing devices during intake workflows.
Users can utilize the returned data by checking the `esim_compatibility` field to determine if a device supports eSIM, and the `number_of_sim_cards` field to understand the device's SIM capabilities, aiding in customer support and onboarding processes.
Standard data patterns include a clear indication of eSIM compatibility (true/false) and a numeric value for the number of SIM cards. Users can expect consistent JSON structure across responses, facilitating easy integration into applications.
