Software and gateway availability

Our SMS gateway software and API are extremely stable and we have an uptime of 99.9%. We continuously monitor our servers so that we can intervene quickly when a technical problem occurs. For large maintenance operations, we will always warn first when the maintenance will take place.


  • 99,3% of the messages are delivered within 10 seconds.
  • 99,7% of the messages are delivered within 20 minutes.
  • You receive a concise report of the non-delivered SMS messages (eg. number nonexistant).
  • Smstools is always dependant of third parties (operators) and therefore we can never guarantuee 100% delivery.
