Need mobile internet access

Currently i live in chennai.....i have n95 8gb mobile compatible for high speed internet access.....i also use laptop......i got a job offer in mussorie(uttarakhand) but will stay there for few months and again will be shifting to hyderabad/mumbai/bhopal/Chennai....

I need internet access for my mobile as well as laptop while i travel in train,where i stay etc...... most important requirements -- speed should be high, coverage should be large.....i m not a big downloader but will use it surfing internet, Video calling,watch tv,hearing news etc

budget- i can pay rs 500 to 1000 per month including for the voice calls i make(is this necessary) for mobile and another Rs 500 to rs 1000 month for my laptop internet access

Can u please suggest a suitable service provider and plan with tariffs based on the above requiremnts because i m really confused with the service providers?

A 3G connection for your mobile phone suggested.
BSNL/ AIRTEL/TATA/Reliance

While travelling in train, neither phone contact or Internet connection can be guaranteed always , as the tower access may not be available..

Option 1:
1. Get 3G modem card for your laptop.
( if your OS is Windows 7 and having wlan ethernet card
application "connectify" can give wifi access to your mobile phone

option 2 :
2. Get 3G connection for your Mobile and connect to laptop with a
dongle.

3.

SO which is the best 3G mobile service which has good speed and better coverage allover india?

I recently came across some attractive plans for data cards & GPRS from Idea, you can check out them.
