Hello Peter,

This error message comes from the modem, it means that the message could not be sent because there is a problem with the connection of the modem to the mobile network.

The error messages that GSM modems give back do not always reflect the real cause of the problem. This error could also mean that the network has rejected the message for some reason, for instance when there are insufficient SMS credits for your SIM card.

Regards, Henk
