Is it possible to avoid SMS messages delivered multiple times?


Generally, this should not happen. However, there may be rare situations that may cause multiple message delivery. Assuming that your system sent out the message only once and only once to tyntec, you can check how many messages were actually sent by:

  • Checking your own system or back-end
  • Checking your sent messages via tyntec’s message tracker on Business Center

Even if you sent one text message, multiple message deliveries can occur if a node involved in the delivery process doesn’t confirm the message receipt. This triggers a resend by tyntec’s SMS platform, which can result in the issue of multiple deliveries.

If you experience multiple deliveries, please contact tyntec’s support team at support@tyntec.com.
