In Nov 2007, I had purchased the so called "tata Indicom CDMA 1x plug2surf USB modem".
Unit was received within 4 working day(after 6 phone calls to remind them)
Connectivity Home town:
Excellent - connects in less than 5 seconds.
Speed:
Real download speed is 136Kbps and upload speed is 43 Kbps. However, this speed is not constant and may vary through out the day. I used https://speakeasy.net/speedtest/ for speed test.
Connectivity outside home town:
Zero - mine just did not work.
While purchasing this device I was assured that the modem would work outside my home town location( Goa). Two days after purchasing the modem I had to go to Mumbai and found that the modem would not work. It shows full network strength, it appears as if it is connected to the net but when I try to surf or send email . nothing happens. I was in Mumbai for 4 days and kept trying everyday. same results.
When I got back to Goa, the modem started working again . so I decided to complain about it(took me over one hour as they kept transfering me from department to department). It is now two days since the complaint was made and the issue has not been resolved.
I think performance of the unit also depends on its location and density of users within the area.
Billing:
I have yet to receive the first bill so right now I cannot comment on it. I keep my fingers crossed.
Do I recommend this product?
If you are located in a area where there is likely to be lots of users of this product then personally, I think you should avoid buying this unit. Ditto, if you are located in a area away from the tata tower.
Cheers!
