When we started for this vacation I was bit worried about internet connectivity from the Tier-II / III towns (Darjeeling, Kalimpong & Gangtok) with my Reliance data card. But, I am pleasantly surprised and glad to report that my data card working exceedingly well from all the towns I have been in the past week.
I am now near Gangtok and able to post and upload reliably with my Reliance data card. This is simply wonderful and something I didn't quite expect.
ps: It's a different story as to why I want connectivity and lug my laptop around on a vacation. That's the question my daughter asked me and I didn't have an answer to.
