My 2 cents:
I have been using it for years. For the first few year they had 128kbps there but last year when I was there, I changed it to 256kbps to actually get some work done remotely. The difference in quality of a call  is the day and night  for about Rs300 a month difference. Highly recommend it!! The best thing ever and the router is hooked up to inverter out which takes so little power, I can call anytime now regardless of the load shedding.
