# Compatibility Check

Simbase SIM cards are compatible with any device that has a SIM slot. However, different regions (Americas, Europe, or Asia) use different frequencies. So make sure your device is compatible with your location. The device documentation should include this information and usually, it shows the region directly.

 

Another thing you can check is the cellular network technologies the device supports. Certain devices only support a single network technology, like 2G / GSM. Check if the network technology is supported in the region you want to use the device. Use our [coverage page](https://www.simbase.com/coverage-maps) to see if the country provides the network connection you need. Your device will not connect if it tries to establish a 2G connection in an area that switched off the 2G network entirely.

 

This can happen with low-cost GPS trackers on 2G in the United States, Canada, or Australia, for instance. These countries simply don’t support such technology anymore.

## 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://support.simbase.com/device-configuration/compatibility-check.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.
