Airtel — can not send message to port number 1900

Address:

Gurgaon, Haryana, 122103

I have been trying to send a message to a port number from a week but I can not get the message. And whenever I call the customer number, those people ask me the number of the message center, someone tells me something, then some.
But no one has solved my problem yet, I just have to send a message and I do not have to stay this company because they make Airtel customers just crazy

Please Help me.

Thanks:
