sbhas2k said:Still my problem is not solved.. any tips to active HSDPA ??
Things like activation of hsdpa and being charged for that is a thing of past. MTNL website is not updated with this information. If you go to MTNL Mumbai's New website (currently beta) you won't find mention of separate activation of HSDPA.
Also in MTNL Mumbai prepaid, the only apn that worked for me for three series (9957/9969/9869) on prepaid is gprsppsmum. Some users had success with pps3g apn also. mobitv is another apn that has worked for some for internet access as well.
End result is that for 4500 unltd recharge you'll get reasonable good speeds but don't expect that you'd be able to do heavy downloads, particularly if you plan to use it in Mumbai itself. This is not a replacement for your regular broadband connection.
Disclaimer: All of above is of course my personal views and I'm sharing what I've experienced. Please don't bash me if some one is getting very good or very bad speeds. By reasonably good speeds I mean around 512kbps in MTNL Mumbai network and I'm satisfied with it as a Internet on the GO facility. I'm happy that I don't have to pay 30p/20kb for data and that too billed incorrectly ( I hope HAWA tel doesn't sues me for this).
