# Coverage Explorer

> Use Coverage Explorer to find network coverage and rates available on a data plan. Find specific details with search and filters by profile, RAT, and country.

Coverage Explorer lists out all the **networks** and **rates** available to SIMs on a data plan. You can search and filter by profile, RAT, and country to find specific details. Rates displayed in the Coverage Explorer are determined by the SIM's current data plan.

Each data plan supports specific connectivity profiles that may be installed on SIMs. SIMs activated onto a data plan may have different coverage and rates based on the profiles installed on the SIM.

<Note>
  **Note:** Data plan coverage includes networks and rates for **all profiles** available on the data plan, not just coverage for the SIMs you have selected.
</Note>

## How do I find coverage and rates for a data plan?

## How do I find coverage and rates for a single SIM?

Coverage details for a single SIM are available in the SIM's **Coverage** tab. Coverage available to a SIM is determined by the SIM's active data plan, and the profiles installed on the SIM card. The enabled profile on a SIM determines networks it can connect to.

<Card title="View coverage and rates for a single SIM" href="/dashboard/sims/sim-details-coverage-tab" icon="globe" horizontal />

## How do I use Coverage Explorer?

### Search

Filter the table by network or country names using the **Search** bar.

### Filters

* **Profile**: Filter by all profiles installed on your SIM, or choose a specific profile to see coverage and rates for a particular Mobile Core Operator. This is especially helpful when evaluating backup coverage on Hyper SIMs with Outage Protection.
* **RAT**: Filter by supported Radio Access Technologies such as NB-IoT, Cat-M1 (LTE-M), or 5G.
* **Country**: Restrict results to specific countries.

### Coverage table

The table lists all networks your SIM can connect to, based on its enabled and installed profiles, and shows the rates determined by the SIM's current data plan. You can sort the table by network name (default) or country name.

<Accordion title="Field definitions">
  <ResponseField name="Network">
    Network name. The last connected network for your SIM displays a "Last seen" label.
  </ResponseField>

  <ResponseField name="Profile">
    Profile the network is available on.
  </ResponseField>

  <ResponseField name="Rate per MB">
    Data usage/overage rate when using data on this network, as determined by the SIM's current data plan.
  </ResponseField>

  <ResponseField name="Country">
    Country the network operates in.
  </ResponseField>

  <ResponseField name="RATs">
    Available Radio Access Technologies for this network/profile/country combination.
  </ResponseField>
</Accordion>

### Export to XLSX or CSV

Generate and download a full coverage list for your SIM, including detailed network metadata. Exported data includes the following fields:

* **Profile name**: Name of the profile the network is available on.
* **Network name**: Name of the network.
* **Rate per MB**: Data usage/overage rate when using data on this network, as determined by the data plan.
* **Country**: Country the network operates in.
* **UNC**: Hologram's Universal Network Code that determines network-level billing rates.
* **TADIG**: The TADIG for the network.
* **MCC**: The Mobile Country Code for the network.
* **MNC**: The Mobile Network Code for the network.
* **RATs**: Available Radio Access Technologies for this network/profile/country combination.

### Deep link with URL filters

Share or bookmark a filtered view of coverage and rates by appending URL parameters. Supported filters:

```text theme={null}
?coverage=PROFILESHORTNAME|ALL
?rat=RATNAME|ALL
?search=SEARCHTERM
```

<Note>
  **Note:** Access to some networks requires custom data plans. Review Hologram's public <a href="https://www.hologram.io/coverage/">coverage page</a> and <a href="https://www.hologram.io/contact-sales/">contact sales</a> if you need tailored coverage.
