    1. Hi Paul

      after the AT+CMGS command youi must wait for hte prompt > to send message text.

       

      In fact the thirdCMUX frame you got:

      F9 05 EF 05 3E 20 51 F9

      is hte char > 

       Please retry sending first a frame with AT+CMGS=<NUMBER>, wait for the > char and then send text.

      This is the correect sequence
