Problem in establishing GPRS connection to server

[sunny_saha007]

Hi,
Basically am trying to establish the GPRS connection to send data to my server and also receive data to my server. Programming it through a Raspberry pi. While I was in India the Airtel connection would work and data being sent and received, as I moved to Australia, I tried the same with Airtel on roaming but gives me AT + CIIR *PDP : DEACT, what does this mean ?? All the data and roaming are on. Apart from that, I did try the connection with Vodafone on the sim900 but it gets connected but fails to send and receive data. Keeping the codes below , help would be appreciated.

def Gprs_Init_comm():
	ser.write("AT+CIPSHUT\r")
	sleep(2)
	ser.write("AT+CMGF=1\r")
	sleep(5)
	ser.write("AT+CIPMUX=0\r")
	sleep(5)
	ser.write("AT+CSTT=\"www.airtelgprs.com\",\"\",\"\"\r")
	sleep(7)
	ser.write("AT+CIICR\r")
	sleep(5)
	ser.write("AT+CIFSR\r")
	sleep(5)
	ser.write("AT+CIPSTART=\"TCP\",\"52.11.214.114\",\"85\"\r")
	sleep(8)

Subsequently changed the code to live.vodafone.com ... Gets connected but does not send data.
