Vodafone India — port

Address:

Mumbai City, Maharashtra, 400076

Right now my number is from Vodafone Mumbai. I am sending SMS to 1900 for porting out to Vodafone Rajasthan. I am trying to send message to 1900 to obtain porting code but even after several days to efforts using different handsets, I am unable to send the message to 1900, I do not know if Vodafone has stopped my message to 1900 or not. I really need to get the porting code. All my bills are cleared (everytime) and I have a NR 3000 deposit with Vodafone. Everytimes I try to send the message, it shows can't send. Please help me in resolving the problem.
