Hello Diego,

Unfortunately, CMS error 500 of the modem means that it reports an unknown error that tells you nothing about the underlying cause of the problem, just that it was not able to send the message. It could be that the connection to the mobile network is unreliable, that the SIM card does not have any SMS credits, that the mobile network blocks your messages or any other potential problem.

If unplugging the modem does not help then there is not much more you can try, but you might try to use the SIM in a normal phone and test if you can send SMS messages with the phone. Then you know at least that the SIM card is valid or not.

Regards, Henk

Hello, I was able to send 7 sms, with a delay of 5 seconds between each sms configured on the soft.

The next messages on the Q are not being send. I get:
Status: 300, Error: Unknown error after PDU sent.
Error: 500, CMS error: Unknown error

On the STATUS TAB on Diafaan, I see 100% signal, network 3G GSM, operator name ok,. and status = "ready to send and receive messages".

I tryed to unplug and reconnect the modem, and it's still not sending the messages, with the same error.

Thanks!
