Desirable stuff: BSNL EVDO Internet Access

I've been planing to get a EVDO connection for last 3-4months, since I am aware of BSNL coming up with their EVDO service. One of my co-worker already got EVDO enabled so I could quickly test the same. Following is quick summary:

Service:
• From BSNL only
• fixed to device MAC, no-roaming
• said to be backed by WLL
• though falls back to CDMA when out of EVDO cell
• needs clarification on BSNL EVDO being a WLL based service

Device:
• ZTE USB Modem works with Fedora 9
• run modprobe after plugin of device 'modprobe usbserial vendor=0x05c6 product=0x3197'
• Use device node '/dev/ttyUSB0' to configure connection using system-config-network or other tools.

Pros:
• Good 'average' speed of 200-300kpbs at my location when tested in Pune, India
• Unlimited package of Rs. 500/- per month

Cons:
• Only USB device available as of now
• No roaming out of city of purchase (or State, anyhow no national roaming - sucks)

Recommendation:
Should be a cost effective option for Fedora Users & Contributors in semi-urban or rural India, as BSNL appears to be at good pace to extend national coverage of its EVDO or at-least CDMA service. From my experience of CDMA service 3-4 years back in hometown I'll know even VoIP performs well on CDMA. (No Benchmarks provided by me as of now)
