How do you get Market to work when Android is Unable to Access Android Market? Right now I am using HTC Hero, having firmware Android 2.1 and I have attached VODAFONE, India SIM-CARD in this phone, and also having Wi-fi connectivity.

Whenever I try to "sign-in" to Android-Market using Google Account, it is always showing "Can't Establish a reliable data connection to the server" titled error with the message "This could be a temporary problem or your phone may not be provisioned for data services. If it continues, call Customer Care."

Now what do I have to do to access "Android Market" from my HTC Hero phone?
I don't know if this helps, but with SFR, in France, I have nearly the same issue ; i can't use the market OTA (unless I use WiFi).

It is due to limitation from the carrier ; perhaps rooting the phone could help to get rid of that limitation.
