Hi,

This error indicates that there's something wrong with your connection or the SIM card plan, more detailed causes:

  • The phone number you try to send your message to is invalid
  • There is no network coverage
  • You don't have enough money on a prepaid subscription
  • The short message service center of the GSM network operator is temporarily out of service
  • The GSM cell is overloaded

Please check if you have the antenna connected and card works normally with other devices (can send SMS messages and so on).

EB.
