CMS ERROR 305 means Invalid Text Format
CMS ERROR 305 表示文本格式无效
The AT command to get in Text Modeis AT+CMGF=1And PDUencoding is AT+CMGF=0
进入的AT命令Text Mode是AT+CMGF=1，PDU编码是AT+CMGF=0
In Text Mode, encoding of the text when sending a SMS is important too.
Standard GSM Encoding is AT+CSCS="GSM"
在 中Text Mode，发送短信时的文本编码也很重要。标准 GSM 编码是AT+CSCS="GSM"
And to be on the safe side, start with at AT&F(Factory default configuration). You can issue an AT&Fcommand at start of your session to overcome possible strange settings that may be stored in the modem.
为了安全起见，从 at AT&F（出厂默认配置）开始。您可以AT&F在会话开始时发出命令来克服可能存储在调制解调器中的奇怪设置。
