[Q] HTC S710E 3G Network problem

Hi,
I never test with 3G SM before with my phone.
I have changed my Vodafone plan to 3G and started using it.The SIM is working fine with 3G in my old mobile (Sony Ercsson).
When I put the SIM i my HTC it is not detecting 3G Network.If I choose GSM/WCDMA it is selecting the 2G Network and for WCDMA Only option
it is not showing any network.
Please note I am having the HTC mobile fro HTC Hongkong and now using the same in India.
Operator: Vodafone
Activity Performed:
Restart the phone and put off the battery multiple time
Factory Reset
Use another 3G SIM which is also workng in my old phone
Toggling between flight mode and WCDMA.

Results:
Just received the 3G network twice and it was sustained for 20 minutes and so.
Please note I am having good 3G Coverage in my locality and with my old phoe it always come full signal.
