4.2.1.4 <strong>Cellular</strong><br />
This section explains how to set the related parameters for cellular network. The <strong>UR51</strong><br />
cellular router has two cellular interfaces, namely SIM1 and SIM2. Only one cellular interface<br />
is active at one time. If both cellular interfaces are enabled, then SIM1 interface takes<br />
precedence by default.<br />
A typical use case would be to have SIM1 configured as the primary cellular interface and<br />
SIM2 as a backup. If the <strong>UR51</strong> cannot connect to the network via SIM1, it will automatically<br />
fail over to SIM2.<br />
