The DrayTek Vigor2865L series, Vigor2866 series and Vigor2927L series routers have an integrated LTE modem and will accept SIM cards from any of major broadband service providers in Australia – Telstra, Optus, Vodafone, etc., as well as those in New Zealand – Spark, 2Degrees, Vodafone, etc.

This guide will show you how to configure the Vigor2865L, Vigor2866L and Vigor2927L series routers to enable 4G communication via the integrated LTE modem.

We will use the Vigor2865Lac in our example, but the configuration details will be similar in the Vigor2866L and Vigor2927L series routers.

Supported 4G LTE bands are:

  • B1 (2100MHz)
  • B3 (1800MHz)
  • B5 (850Mhz)
  • B7 (2600MHz)
  • B8 (900MHz)
  • B20 (800Mhz) *
  • B28 (700MHz)
  • B32 (1500MHz) *
  • B38 (2600MHz) *
  • B40 (2300MHz)

*Frequency band not available for use in Australia

For 3G/4G coverage areas check with your ISP for the exact frequency band used in your area from the following links: TelstraOptusVodafone and Virgin Mobile

This configuration guide will cover:

  1.        Optus
  2.        Vodafone

Step 1: Insert SIM Card into the Router


  1. SIM 1 is the primary SIM slot and SIM 2 will be the backup SIM slot.
  2. Only one SIM slot can be active at any time.
