We have identified that, in addition to the previously reported impact on United Kingdom Long Virtual Numbers (O2 network), a subset of Swedish virtual numbers is also experiencing inbound SMS delivery degradation.

Affected messages may be delayed or fail to deliver when sent to these Swedish numbers. The issue appears to be consistent with the ongoing degradation observed across certain inbound routes.

We are continuing to work with our upstream partners to investigate the root cause and restore normal service as quickly as possible. Further updates will be provided as more information becomes available.
