Vptcl CDMA related

I have some questions,

1. PTCL wireless is using same CDMA network as VPTCL?

2. If yes, is it possible to get connection of PTCL wireless without paying them anything for the device (just monthly charges)?

3. What is the avg downloading speed at 256Kps for Lahore Alamba Iqbal, University and surrounding areas?

4. Does it gives unlimited browsing + Downloading?

Thanks..

The PTCL EVDO uses CDMA but you cannot buy your own usb and start using ... the USb is first configured to the PTCL network then i will be able to connect with ptcl network
