Vigor LTE Routers have a built-in LTE modem inside the router and SIM card slot; therefore, it's no longer necessary to have a compatible USB dongle to use 3G/4G/LTE Internet Access, we only need to insert a valid SIM card and configure the WAN settings as follows.

1. Use a screwdriver to remove the security cover of the SIM card slot. Then, insert a SIM card.

3. Configure LTE WAN: Go to WAN >> Internet Access >> LTE Detail Page,

• Enable 3G/4G USB Modem (DHCP mode)
• Type SIM PIN code if the SIM card has one
• Enter APN name according to the ISP
• Click OK to apply

After the configuration above, if connection establishes successfully, the status of LTE will be shown on the right of the Dashboard.
