This causes a failure in the next attempt (by the modem in the device) to send data, which typically causes the device firmware to restart the connection. Restarting the connection can be useful if you suspect the firmware or modem are in an unusual state, or to terminate data sessions. For example, if an operator API gateway does not support [RADIUS](/glossary/glossary.md) packet of disconnect (PoD) messages, the cancel location procedure can terminate the data session between the device and the operator API gateway. | | SIM Timeline | Select to display a timeline of SIM activity for all IMSIs related to the ICCID. | ## Related tasks Back to overview --- # Agent Instructions This documentation is published with GitBook.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://docs.eseye.com/infinity-classic/manage-your-sim-estate/sim-actions/use-the-sim-control-panel.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
