# Access SIM Card Usage and Info as JSON via API

### 17, Dec 2021

You can now access detailed metrics about your SIM card data usage and sessions in JSON format via the Telnyx API.

Using the Detail Record Search API with `filter[record_type]=wireless_detail_records` yields detailed session information including session start and end times, SIM card information, data usage and cost.

See the [API specifications for searching detail records](https://developers.telnyx.com/api/detail-records/search-detail-records) to get started, or learn more about SIM card reporting and analytics in our [support knowledge base](https://support.telnyx.com/en/articles/3679913-sim-reporting-analytics).
