This is the demonstration of sending SMS using my ZTE MF-190 modem from TP-Link MR3020.
This modem have 2 serial ports, so I can send SMS and dialing internet at the same time. If your modem only have single port you need to disconnect 3G connection first.
There are few packages need to be installed so make sure you have enough memory and remaining space.
There might be a need for you to mount remote filesystem from another linux box, in my case I was doing cross compile packages and stuff from my remote linux server. It would take less time if I can mount this remote machine to my router so I don’t have to download and transfer or tar and untar the files.
Currently as the time of this post is written October 13, 2014 most of the Malaysia’s ISP have not yet supported IPv6 natively. They also disable ping and the using NAT. One of the left choice of option for me to get IPv6 on my router is through Tunnel Setup Protocol (TSP). There are few broker that offer this type of tunneling, one of them is gogo6/ Freenet (http://www.gogo6.com/main)
This post I expect OpenWrt has been installed, if not please refer my previous post. The full documentation about Extroot can be found from this link http://wiki.openwrt.org/doc/howto/extroot .
The step showed here is the working implementation on TP-Link MR3020 using the following environment.

1. USB 2.0 Hub
2. USB 2.0 Flash Drive (~8GB)
3. ZTE MF-190 3G Modem
Less than 3 hours after I purchased the 3G/4G Wireless N Router TP-Link, model TL-MR3020 the router already been flashed with custom firmware you know OpenWrt 🙂
