I have been a user of the 45K plan. I have an MTNL Mumbai prepaird 3G connnection and I am in Delhi for sometime. I could connect using the apn gprsppsmum, a few times. But I am not able to connect for the past two days. For a few times I could connect, the speed never crossed 300kpbs. Is there a similar issue with others too? Or is it just me?
