CHARLOTTE, N.C. – An outage for T-Mobile customers in Charlotte affected their ability to dial 911 in Mecklenburg County, police said Wednesday.

According to Charlotte-Mecklenburg Police, the outage affected some users and prevented them from dialing the Charlotte-Mecklenburg 911 call center. According to CMPD, the issue was resolved just before 3:30 p.m. Wednesday.

CMPD provided an alternate number for affected T-Mobile customers who need emergency services. They can contact the department’s administrative number at 704-336-3237.

The wireless provider released a statement saying that a malware attack via Twitter on Tuesday night "generated some unplanned 911 calls but 911 services and calls were not affected."

"We are obligated by FCC regulations, as is every other wireless carrier, to notify authorities in your city if 911 services might at all be impacted, which is what we did when this problem was first detected. But this actually affected 911 nationwide and on any Apple device running iOS 10 or earlier (regardless of wireless carrier).

The malware has been disabled, but we’re advising our customers who clicked on the link to reboot their phone and update their software to 10.1. We’re also working with Apple to determine if any additional steps are needed."
