Wireless Detail Records (WDRs) provide granular, per-session usage data for your SIM fleet. Each record captures a single data session — when it started, how long it lasted, bytes transferred, and which network was used.

​
Generating Reports

WDR reports are async. Request one, poll for completion, download when ready.
  1. Create — POST /wireless/detail/records/reports with a time range:
  2. Poll — GET /wireless/detail/records/reports/{id} until status is complete.
  3. Download — The report_url field contains a pre-signed URL to the report file.

​
What’s in a Report

Each record includes:

​
Connectivity Logs

For real-time session visibility (not batch reports), use connectivity logs: GET /sim_cards/{id}/wireless_connectivity_logs Returns recent sessions for a specific SIM, including IMSI, IMEI, radio technology, and connection state. Useful for debugging why a device can’t connect or which network it attached to.

​
Use Cases

  • Billing reconciliation — match data usage against your invoices
  • Anomaly detection — spot SIMs consuming unexpected data volumes
  • Coverage analysis — see which carriers your devices attach to by region
  • Troubleshooting — correlate connectivity issues with specific cells or networks
