These errors are returned by the mobile network and indicate that the mobile network is not able to send the message. Unfortunately, the error codes that the mobile network or GSM modems generate are not always entirely unambiguous.
For instance, error code 38 means 'Network out of order', but some mobile networks also use this error code when there are no credits left on a prepaid SIM card or when a message limit is reached for a certain period.
first of all, thanks for your explain about my last topic.
Henk, I started today my tests with diafaan, and sometimes I got 2 errors.
1) CMS 38 = Network out of order
2) CMS 28 = Unidentified subscriber
How I fix this problems?
