There’s still no estimated restoration time for calling issues affecting some of Canada’s biggest mobile service providers.

Text messages, internet, and data services still appear to be up and running but Rogers, Telus, Bell, and Freedom Mobile users have all been tweeting that they’re experiencing calling issues across the country.

Rogers’ customers tweeted to RogersHelps in frustration as many were not able to make or receive calls on Sunday.

RogersHelp said via Twitter that Rogers Communications is aware of the issue and is actively trying to find a solution to the problem.

The problem is reportedly affecting many customers from several service providers across Canada.

It's definitely not a fun situation when you are unable to make or receive calls! We are sorry for the inconvenience this has brought you. Our teams are aware of an issue and working to restore service back to normal as soon as possible. ^EY

Police services such as London Police Service and Chatham-Kent Police Service are asking residents to use other networks to contact emergency services until Rogers has been restored.

It is unknown when the issue will be resolved or what caused the disruption.
