android - smsc 值为"当地短信中心号码",145 后面那个145代表什么，正常么？

+CSCA=address[,address_type]

The address_type Parameter

The second parameter of the +CSCA AT command, address_type, specifies the type of the SMSC address assigned to the address parameter. Two values, 129 and 145, are commonly used.

129. Meaning: The SMSC address is formatted using the typical ISDN / telephony numbering plan (ITU E.164/E.163) but it is not sure whether the SMSC address is an international number, a national number or a number of other types. Example addresses: "85291234567" and "91234567".

145. Meaning: The SMSC address is formatted using the typical ISDN / telephony numbering plan (ITU E.164/E.163) and it is an international number. Example address: "+85291234567".

As address_type is an optional parameter, it can be omitted. If you do so, the GSM/GPRS modem or mobile phone will use the default value of the address_type parameter, which is:

129 if the SMSC address does not start with a "+" character. For example, "85291234567".

145 if the SMSC address starts with a "+" character. For example, "+85291234567".

如果你看不懂英文，我可以告诉你145这个参数代表是一个国际号码，但它不是必要的，如果没有,145，根据你前面的号码看有没有+号，如果有代表是145类型（国际号码）如果不是，则是129类型代表不确定是否是国际号码。

综上，如果你的当地短信中心号码是有效的，就应该是正常的。
