On Monday, T-Mobile, AT&T, and Verizon consumers were bewildered when their calls stopped passing through, which then moved on to be a countrywide interruption of service for T-Mobile’s network, particularly, that persisted for the entire day. Approximately at around 1 AM Tuesday, the company then tweeted that voice calls and text messaging services had been fully repaired.
As claimed by reports on Downdetector and on social media, reports spiked around 2:20 PM ET Monday. Whereas AT&T informed The Verge that its network was “operating normally” and Verizon stated that its network was “performing well,” T-Mobile affirmed that it’ was functioning to fix “a voice and data issue that has been affecting customers around the country.”
Verizon even added that they were not to blame: “We’re aware that another carrier is having network issues. Calls to and from that carrier may receive an error message,” It makes sense that what emerges to be a multi-network breakdown could, in reality, originate from a single carrier, given that individuals are reporting failed calls.
As of 6 PM ET on the very same day, T-Mobile had already reinstated data services, but was still facing an issue to restore phone calls to normal.
At around midnight ET, six hours following the update, T-Mobile wasn’t quite cone yet. “We are recovering from this now but it may still take several more hours before customer calling and texting is fully recovered,” interpreted a blog post from T-Mobile CEO Mike Sievert.
Numerous Verge employees were incapable to place calls on T-Mobile on Monday. It occurred that both Sprint, at present a T-Mobile subsidiary, and US Cellular were also facing similar issues.
Yet it is still imprecise on what the issue might have been, although T-Mobile stated on early Tuesday AM that it was an “IP traffic-related issue that has created significant capacity issues in the network core throughout the day.” Later, FCC chairman Ajit Pai tweeted that this interruption was “unacceptable” and that the FCC will initiate an inquiry.
