Can a telephone number move between devices and networks?¶
Yes. A number can follow a moved SIM, replacement profile or provider port and can also appear on linked devices.
Build a relevant-time relationship table¶
For each period, identify provider, number, ICCID, IMSI, IMEI and handset. Activation, porting and provider records explain transitions. A recovered SIM may have used several phones; a current handset may post-date the activity.
Number continuity is not user continuity¶
The service can persist through sale, loss, replacement or changed control. Combine the technical timeline with possession, account and contextual evidence.
Key takeaway
Reconstruct the number-credential-handset relationship at the event time before attributing calls, messages or user activity.
