Greeting,

Can somebody tell me if using this module (MD720/S300) is it possible to send one message to multiple phone numbers at the same time?
Can this be done by connecting multiple numbers to the command # SMS.TELNO: = CONCAT (IN1: = .......
Did MD720 module supports this sending as a regular mobile phone does?
Thanks in advance

Hi,

the AT command to send SMS (at-cmgs) only supports one telephone number.

I suppose you could program a loop in your project to send the SMS also to more than one numbers but I never tried it.
