|You don't necessarily need data cards to be mobile. You could always use a regular phone-to-laptop data cable, or Bluetooth, and connect via GPRS or CDMA.
GPRS (GSM's wireless data technology package) plans cost as little as Rs 150 per month in some post-paid schemes, going up to approximately Rs 600.
Though real-life speeds for GPRS are reported to be just 56 to 96 kbps, costs are generally not linked to usage time or data transfer, so this works fine for the casual surfer.
Most CDMA (Code Division Multiple Access) handsets have an inbuilt modem, so once it's connected to your laptop, you can dial up and get online. Some users have reported download speeds for CDMA handsets to be about 120 kbps.

|Universal Mobile Telecommunications System represents an evolution in terms of capacity, data speeds and new service capabilities from second- generation mobile networks. Using W-CDMA radio access technology that builds on GSM, it provides a clear evolutionary path for more than 80 per cent of the world's wireless market to offer speeds of up to 2 Mbps, and all the benefits of broadband connectivity while on the move. The protocol was evolved by a global alliance of telecommunications standards bodies headquartered in France.|
|EDGE To GPRS Fallback|
|An EDGE data card can offer high speed connectivity only within range of an EDGE tower. When the user moves into a neighbouring cell site that may not be EDGE-enabled, data access speeds "fall back" to GPRS levels.|
|A group of multinational wireless communications companies have banded together to develop and promote high-bandwidth third-generation (3G) wireless technology. The group, which goes by the name of 3G.IP, includes AT&T Wireless Services (now merged with Cingular), British Telecom, Ericsson, Lucent, Nokia, Nortel, Telenor AS, and Telecom Italia Mobile.
Mobile telephony and the Internet converged to create third-generation mobile services. The first commercial 3G service was rolled out by DoCoMo in Japan in 2001.
3G services combine high-speed mobile access with Internet Protocol (IP)-based services. Technologies such as W-CDMA (wide-band CDMA), CDMA-2000 and TD-SCDMA are deployed to enable access to information, media and entertainment, anytime, anywhere.
