Use AT commands[^] to send and receive SMS via your GSM modem/unit.

Remember that it is using a diffent encoding (GSM default alphabet (GSM 03.38)[^]) where something like sending a "@" char is encoded as 0x00.

Use AT+CSCS to set TE character set to support the correct encoding.
AT+CSCS=? to list all supported encodings. But please note, that not all GSM units/modem support all types of encoding.

To really make it the correct way. You have to switch SMS message format to PDU encoding via AT+CMGF command.
Via PDU format, you can select the correct encoding, make long SMS ( over 160 char ), sending pictures, ring tone etc..

Send and Read SMS through a GSM Modem using AT Commands[^]

Hope it can help you.
