plz help me...
I used m.n.p. and switched to dolphin prepaid(primarily for3g).
But i am not able to use 3g on my phone.
i am in delhi and my handset is Nokia 5800XM. I tried all of the above settings you have written but everytime it says: "packet data connection not available".
i've called mtnl customer care 100 times but with no use. everytime they say one of the following two:-
a) send an sms writing your handset model (for manual settings) - the sms has never delivered.. everytime it says msg sending failed
b) call at 01123627494 but it is also never reachable
plz tell if there's a third option,,, thanx in advance..
According to customer care executive of MTNL set the GPRS setting on your mobile if your handset is 3g enabled then u can access the 3g speed on your mobile automaticaly against GPRS setting.
