Websocket using SIM900A?

can I connect to websocket using SIM900A? please share any code or related documents.
thank you

Directly it wont be possible, you might have to use some websocket library for doing this. There is a lot of handshaking that happens which keeps the connection alive. It needs to be taken care of. SIM900A will only give you the channel of communication through TCP. Rest all websocket intelligence needs to be written.
