What Caused the Cellcom Outage?
The outage began unexpectedly on Tuesday, May 14, around 9:00 p.m. CT, leaving many in northeastern Wisconsin without access to basic wireless voice and SMS services. While the root cause hasn’t been disclosed, Cellcom has confirmed that there is no evidence of data compromise and that the issue does not affect mobile data, iMessage, or RCS features.
What Has Been Restored So Far?
Cellcom has successfully restored its wireline voice services, reactivating communication for some users and infrastructure partners. A portion of wireless voice service has also come back online, but the full system remains unstable. SMS capabilities are still affected as of the latest updates.
The Plan Moving Forward
According to Cellcom’s latest statement, their team is focused on restoring connectivity in a phased and prioritized manner. The first priority is reactivating core wireless voice services.
