Airtel Mobile Office — Speed Reduced

Before one week i have actived mobile office at that time i was getting 460kbps speed but next week suddunly it falls to 115kbps..
whats this is there any standard or not?
And also i am not abale to call on 121.

dear sir,
i am using airtel mobile internet of charges RS.395 per monthly. my problem is that its downloading speed is very slow. (about-1 se 2kb)
i want to increase downloading speed

MY AIRTEL MOBILE OFFICE SPEED IS VERY SLOW.
SPEED IS - 115.2 kbps

First they blocked bittorrent now they have cut speed to about 20 times slow.

It is true they first blocked. Bittorrent. Now Downling is also blocked. Browsing speed has been reduced to about 10-15 times.

airtel provide mobile office service is very bad when i surfing internet google page open after 5 minute this is airtel service
but now days days iam using idea gprs 20 service he provided better speed
i like it idea gprs service and mobile office service is same but idea provided higher speed and downloading speed is 25-30 kbps it is nornally speed of broadband but we can use mobile phone modem and connect pc and uses service
i says that my friends plz uses idea services and happy its speed ok byyyyyyyyyyyy

I have using Airtel(karnataka) 98 unlimited internet from 3 months.
from last 1 month the download and browsing speed is reduced. it also OK..
But, while downloading any file, the downloading process is stopped without downloading...
