I am trying to use the hologram tcp sockets api to send SMS over a tcp connection via a SIM900 device. Currently everything seems to function fine and I received a 00 response from the server, however, the text message is never received on the target device. Also, he message is occasionally received on the target device. Further, I have had much higher success rates when sending the text message on a linux device via netcat.
Here is the sim900 logs
