# Config Network

This article shows you how to check and configure network settings for your Dual Cellular modules (SIM 1 and SIM 2).

After connecting successfully to [**WebApp**](/xblink-duo/user-manual/getting-started/xblink-webapp.md), navigate to **Network** tab.

## APN Setting <a href="#apn" id="apn"></a>

You can configure the APN for each SIM slot independently. We have 2 ways to configure the APN: **Auto** and **Manual**. XBLink supports Automatic APN detection (Default).

### **Auto**

When you insert a SIM card into Slot 1 or Slot 2, its APN configuration is set to Auto mode by default. This meaning is XBLink use information of your SIM such as Cache MCC and Cache MNC to search and choose a proper APN.
