Thanks for reply.
I was out of mumbai for some days , I brought BSNL sim there.
Now in mumbai when it says BSNL Dolphin earlier it was BSNL Cellone. I get download speed of only 0.7 Mb/sec.
Anything can be done about the speed.
1st of all....how did you buy a sim outside mumbai circle....with your current documents of mumbai....
I wasnt allowed to buy a MTNL sim,as my documents were not of mumbai....as i wasnt a native of mumbai....my address proof was not of mumbai....THEY SAID I HAV TO GO TO BSNL CIRCLE... :/
