Teluglobers, I came across this service provider who offers per day mobile hotspot feature. The prices are bit high. In return you get to enjoy unlimited broadband internet for multiple devices. Most of us find a USB based mobile broadband connection sufficient for our needs. For folks with multiple gadgets like tablets,smartphones you are out of luck with the USB drive. The mobile hotspot MiFi comes in handy. These guys provide service on a day basis for $ 15.00 which includes the renting of Mifi device. For quickly connecting to office network or use on your tablets this daily option is fine. Go to their site and check it out. Here is the site . I did a 21 day unlimited pricing. The total came to $ 295.00, which is expensive for most. For those who really need a good network this is great.

Lately TATA has started selling a Mifi hotspot. I best you can get it cheaper than this MiFi. Here is the link for the TATA Photon.
