Sound like crazy ?, of course yes !!! but seriously I'm going to share a fantastic trick by using you can double up your internet speed. Let's read below:

Pre Requisite :

1. You Should have more than one working internet sources.
That's it.

How to setup :

1.install dispatch and run
2.click start
3.it will detect active adapters automatically
4.select those adapters as primary whose speed u wanna combine.

 

Connectify dispatch features:

1. If u have limited plan in some u can allot that much bandwidth
2. Keep other adapters as secondary which you want to use only in case primary adapter fails
3. Share combined speed as a single connection through Wi-Fi or LAN whatever suitable.

1.I have tried Phone + wifi +3g dongle and it worked successfully.

practically u can combine all which u have (because practically u wont have more than 4 to 5 sources.

2.can we use two data cards simultaneously yes of course but they should use different adapters.
