What records might a mobile-network provider hold?¶

The provider may hold subscription, billing, activation, SIM replacement, porting, call, messaging, data-session, device and cell-site records.

Records describe network events¶

Calls can include numbers, time, routing and duration; SMS records often show an event but not text; data sessions show network use rather than a website or app. IMSI, ICCID and IMEI can link subscription credential and handset.

Request and interpret precisely¶

Availability varies by provider, service, jurisdiction and retention. Specify identifiers, event and period and preserve where loss is credible. Subscriber data names the account holder, while cell sites and connections identify infrastructure - not exact location or human use.
