What does “delivered upstream” mean?

This means that the SMS has been submitted to a network but no status report has been received from the mobile network.

There are several factors that can contribute to the message delivering swiftly by the carrier:

  • Recipient signal strength and connection to the network
  • Problems with the network
  • Carrier issues.

To track down the delay, please check your delivery reports and error codes that are available in our customer portal my tyntec.
