BSNL Wi-fi Hotspots Locations in Trivandrum now include Muscat Hotel and Nila building, Guest house at Technopark in Karyavattom. This was installed sometime back in Feb 2009 or so , but so far I have heard no one using it. I will test this on Monday.
BSNL Wi-fi Prepaid Card in Thiruvananthapuram. The usage instructions are simple. There is a 13 digit pin number which will help you to create a login ID. This is a quantum jump by BSNL who require every details upfront before we use any of their service.
I bought a card for 110 Rupees . It has a validity of 15 days. and 100 minutes usage time. This can be used at Nila building in technopark and at Technopark guest house is what BSNL claims. I will test this on Monday. The type-A hotspot has a better range than Type-B hotspot. The type-B hotspot of BSNL is at Muscat Hotel.
