ERROR 001

Failed to deliver SMS to handset


Messente was unable to deliver the message. Usually the reasons for the failed messages are:

  • Invalid number format
  • Operator-side error
  • Phone switched off
  • Signalling issues
  • Deactivated or unallocated number

When the message fails with the err=002 you can try again after a few hours. There are some temporary issues that might cause the message to fail to deliver on the first attempt.
