Timeline of updates

  1. resolved

    We identified an issue where devices using Super SIM may receive duplicated MT SMS Commands. The error rate is estimated to be 0.084%. By design SMS may be delivered multiple times. For customers who are sending several Commands in a short period, devices are more likely to receive duplicates. We confirm that MT SMS Commands are billed exactly once, even when delivered multiple times. We have identified the sender(s) with the highest impact and provided a mitigation. We've proceeded ro resolve this incident.
