推荐答案

使用AT命令（GSM设备或移动设备连接PC） ）

可能是您的设备只允许在一条消息中 128 字符。



您可以拆分长消息两个或多个短信。 因为在这种情况下（对于AT命令），如果您的设备每个sms仅支持128个字符，则没有额外的设置可用于将当前设备中的限制从128个扩展到160个字符。



您也可以使用第三方批量短信服务...

：）

using AT-commands (GSM-device or mobile attached with PC)
May be your device allowing 128 chars only in a single message.

you can split long message in two or more sms. because in this case(for AT-commands), if your device support only 128 chars per sms then there are no extra settings available to extend the limit from 128 to 160 chars in your current device.

you can also use 3rd party bulk sms service for this...

Happy Coding!
