I came accross a problem today, when i bought a new Wireless router that i purchased to create a wireless network for my home using my 3G wireless device. I am using PTCL EVO and here is a quick guide for your PTCL EVO wifi configuration that you require to make it work with your device
Click on Manual configuration for the 3G Device as most of the Routers will not support local (pakistan) based service providers
Enter Dial in number: #777
Username should be: firstname.lastname@example.org
Leave APN blank as you will not need it for this configuration.
Once done save your settings and Restart your wireless router, that’s it. Enjoy your 3G freedom.
