# Mobile network

View cellular status, SIM details, signal strength, and APN.

**Mobile network** displays cellular connection status, modem and SIM identifiers, the current network operator, IP address, signal strength, and APN.

The Hera 604 holds three SIMs:

* `CHIP`, an embedded SIM built into the unit.
* `SIM 1`, the first removable SIM card slot.
* `SIM 2`, the second removable SIM card slot.

A cellular profile pairs one SIM with an APN. The router uses one profile at a time. **Active SIM** and **APN** show the active profile.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

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/hera604/configure/system-status/mobile-network.md?ask=<question>&goal=<endgoal>
```

`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.
