I have interface PIC16f877A with sim900a directly. I can send SMS but in case of Receving/Reading an SMS from sim900a I am failing.
I am unable to find the error, has anyone had a similar experience?
Are the indicators for receiving an SMS message set correctly in the modem?
Ensure:
AT+CNMI=1,1,0,0,0

I am trying to test a service. I need Twilio to receive SMS from specific SMS service provider. When the sender sends with a number I can receive the message. But when the sender user SenderID like 'RZ SMS' I can not receive the message. The structure of the message in both situations is the same.
Has anybody faced this problem before?

It is not possible to respond to SMS messages sent from an alphanumeric ID. You also cannot initiate messages to an alphanumeric ID. Please see more details on alphanumeric sender IDs here: https://support.twilio.com/hc/en-us/articles/223181348-Getting-started-with-Alphanumeric-Sender-ID
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.

Sowmya
Have you tried sending the message using a terminal. Use the AT Commands to configure in PDU mode and send a text message through terminal. Most probably, you might have missed some endline characters or something. However, if you are getting CMS error than there must be something wrong with your network registration.
Please feel free to ask more about the issue. Thanks
Apple just releases Yosemite which allow us to send sms message (via phone) using SMS Relay (Continuity). Does anyone know how to write applescript to send sms message. (I know that we can use applescript to send imessage).
One more question that, can we use applescript to get list of message rooms or messages in a room from Message app.
I'm developing a winform program in which, I need send and receiving SMS messages, I have no problem in sending SMS, but i don't know how to inform when a new message has been received in a gsm modem? I wanna have an acknowledgement like an interrupt or event, when a new message has been received. As far as I know i should work to at+CNMI or at+CNMA, but unfortunately i cant find an example for those.Furthermore I wanna know how to get delivery message or how to handle that? Thanks in advance.
Depends on device type you are using. Use AT+CNMI=? to see all possible options your device supports.

Anybody had experience with that?
