Several users of Google Fi have recently faced a ‘SIM card is no longer active’ message, resulting in interruptions to their mobile data services. This problem started on March 31, 2026, impacting users across different devices and locations without any clear trend. Google has recognized the issue and is diligently pursuing a resolution.
In the meantime, a temporary solution has been recommended by some users and support representatives. This involves turning off and then turning on international calling options within the Google Fi application, which has reportedly restored services for certain users. To implement this fix, users should access the Fi app, go to the Home tab, select ‘Calls to non-US numbers’ found under ‘International features’, disable it, pause for a moment, and then enable it once more.
Google has acknowledged the situation on its support site, urging users to remain patient while they work on a fix. The company has also indicated that support wait times may be extended due to a surge in inquiries. As the circumstances progress, users are encouraged to keep an eye out for updates from Google concerning a permanent solution.
