Am using sim300 gprs module for ppp connectivity.i have tested this on both airtel and hutch.airtel doesn't support to other browsers b'coz they are using proxy servers.when i used to connect it with hutch i can't go it with ppp connection when i used micro browsers its working but am trying it to connect it with hyperterminal but it wont work when i used the diualing number *99# with give connect data and i think it is sending the lcp linking packets and after sometime it is saying that no carrier.
hope anyone can give me any suggestions
