# Roaming

Each module vendor has their own commands to enable roaming (it is not a standard AT command). Below we list the commands to enable roaming on a few modules types.

## Quectel <a href="#atcommands-networkselection-operatorselection" id="atcommands-networkselection-operatorselection"></a>

To enable roaming on Quectel modules, we can use the following AT command:

{% hint style="info" %}
AT+QCFG="roamservice",2
{% endhint %}

## U-blox

To check the network registration status of the SIM, we can use the following AT command:

{% hint style="info" %}
AT+UDCONF=20,1
{% endhint %}
