Hi Anton,
I’m using jasmin and have added the SMSC creds and left the Module sender ID empty, then when i sending the msg, log gaves me failed.
But when i’m filling the Module sender ID in SMSC it working and delieverd.
my porpuse is to send the msg from playsms without sender ID because i’m already set a default src-addre on jasmin itself and it’s working properly when i tested it by API link.
