Frequently Asked Questions
Does the TL-MR6400 work with Australian carriers?
Yes. The TL-MR6400 supports 4G Band 28 (700MHz) and Band 5, which are used by Telstra, Optus, and Vodafone across Australia. Band 28 in particular provides strong regional and rural coverage. Always confirm band compatibility with your specific carrier plan before purchasing.
What SIM card size does the TL-MR6400 use?
It uses a Micro SIM card. If your carrier provides a Nano SIM, you will need a Nano-to-Micro SIM adapter, available from most electronics retailers.
Does this router include a SIM card or modem?
No. The TL-MR6400 does not include a SIM card or modem. You will need to supply your own Micro SIM from a compatible Australian carrier with an active data plan.
Can I use the TL-MR6400 as a backup internet connection?
Yes. The LAN/WAN port can be configured as a WAN port, allowing you to connect a fixed-line modem as a primary connection while using 4G as a failover — or vice versa.
Is the TL-MR6400 compatible with the NBN?
Yes, in Wireless Router Mode for FTTP (Fibre to the Premises) and FTTH (Fibre to the Home) NBN connection types. It is not designed to replace an NBN modem for other connection types such as FTTN or HFC.
Does CCTV Guru ship Australia-wide?
Yes. We ship to all states and territories across Australia. Orders are dispatched promptly from our local warehouse.
