Network connectivity issues that had obstructed Utah cellphone users’ access to 911 this weekend were resolved for all the affected communities by Sunday afternoon.

The problems centered on Salt Lake, Davis, Summit and Washington counties. Provo police also reported issues.

Some authorities initially pointed to a Verizon power outage causing the issues but later said the issues affected users with other cellphone providers.

Earlier this weekend, those in Salt Lake City and Sandy could call 801-799-3000, option 7, if they couldn’t get through to emergency responders by dialing 911, SLC911 Communications Bureau advised in a news release.

SLC911 Communications Bureau said around 7:40 p.m. that users were still experiencing problems and said it would work throughout the night to fix them. Officials were working with cellphone carriers and Century Link communications services to fix the problem, SLC911 said.

In the meantime, agencies had shared alternative numbers to call for emergency help.

• Those experiencing issues in Provo can call 801-852-6210, police said.

• People needing help in Bountiful, West Bountiful, Centerville, North Salt Lake or Woods Cross can call 801-298-6000. For the rest of Davis County, 911 services are available at 801-451-4150.
