推荐答案

命令AT+CSCS?将回答您使用哪种类型的sms编码.正确的答案是"GSM"，如果不是，则应通过命令AT+CSCS="GSM"进行设置.

Command AT+CSCS? will answer You what type of sms-encoding is used. Properly answer is "GSM", and if not, You should set it by command AT+CSCS="GSM".

请记住有关"Ctrl + Z"(而不是"Enter")作为短信文本的结尾.

And remember about "Ctrl+Z" (not "Enter") as a finish of sms text, please.
