D-Link adapter- work for all sim cards. Review on D-Link External Modem

Here is introduction about this modem:

This is USB net connector, mostly uses for USB internet, its for prepaid connection, any sim card we can use through this net connector, its basically made for 3G connection, getting in price of Rs.1950. I bought this modem before 2 weeks, I have some good experience as well as bad one..

Good points:

Work for all sim cards(airtel, vodafone, IDEA, any other)

You can select any option like 2G or 3G through setting according to that money will get deduct

I am using my mobile sim card of Airtel and for 3G its giving very good speed. Very easy installation process(like plug and play). Can be install on laptop, desktop. Work for all OS(including Windows, Linux, Ubuntu)

Working for all browsers

Now bad experience:

1. 2G speed is very low

2.if antivirus installed, driver will not get easily install and modem will not work

3.cost is high as compared to other modems
