Hello,
I am using wavecom gsm modem and implemented the logic to send sms in pdu mode. But for some operators I am getting : +CMGS response but not receiving the message. And with few more operators like idea, airtel, vodafone etc, with few SIMs I am getting +CMS ERROR : 38, i.e., Network out of order and few with proper response but not receiving SMS.
Has anyone faced these kind of problem? And Can anyone help am I missing something?
Is it the network operator issue?
And I also tested with Quectel modem, but the same result.
Regards,
Sowmya
