The problem still persists. If i change my network settings from WCDMA to GSM in the network properties then it connects alright and stays connected for a while.When in WCDMA max is 1 minute and then it disconnects. Hope they fix it soon.About time that MTNL realises that access to data network is a critical service .Outage as long as todays isnt within acceptible.Going out of town shortly and will be in BSNL Roaming in Goa . Hope it works properly over there .
