Hi i am in chennai now and i am using bsnl sim of kolkata.i am having problem with my bsnl 2g sim. everytime when i recharge any new bsnl sim by 270 Rs i get good speed like 3g and my bsnl datacard shows HSPA network but from the second recharge i get very bad speed and my bsnl datacard shows HSDPA network instead of HSPA.

can anyone plz tell me the reason and solution for it.thanks in advance.

It is known problem with BSNL, what they do is that when you connect internet first time after recharge, they give 3G speed but if you disconnect reconnect then you get slower 2G speed.

Am right, is this the case with you also ?

no untill the usage is not getting over it gives very good speed.
but after that when i go for a second recharge of 98 or 270 it gives too much bad speed

Over usage.. what do you mean by that ?

Also, how bad speed you get , can you test and tell me because I am also planning to a BSNL sim for net usage only.
