On Monday, T-Mobile customers faced issues with their network as they were not able to make phone calls or use the internet. There were also some disruptions in the networks of those customers who used other wireless carriers to reach T-mobile lines.

The company responded by saying that these outages were caused by a “widespread routing issue affecting voice and text.”

At 1 am ET on Tuesday, the president of technology tweeted that voice and text services have been restored.

“Thank you for your patience as we fixed the issues,” Neville Ray tweeted. “We sincerely apologize for any and all inconveniences.”

The service-tracking site Down Detector said that they received more than 100,000 complaints from the United States on Monday afternoon. In the evening, the reports dropped down to 25,000 and by midnight, there were only 1000 customers who were unable to use the network for making calls or internet

The Sheriff's Office situated in Harris County, Texas said that the outages made it difficult for many people in the region to contact 911.

Down Detector also recorded thousands of reports of Verizon network outages on Monday but the company has denied all such claims. Verizon spokesperson Karen Schulz said, “Sites such as Downdetector.com utilize limited crowdsourced data drawn from sample social posts which are often statistically insignificant or factually incorrect.”

“Verizon's network is performing well,” Verizon spokesperson Howard Waterman said in a statement to CNN Business. “We're aware that another carrier is having network issues. Calls to and from that carrier may receive an error message.”

AT&T also said that if their customers were facing any issues, it is because of T-Mobile’s outages. “Our network is operating normally, but it's possible some customers are unable to reach people on other carriers' networks,” AT&T News said in a tweet.

While Sprint was also present in the list of complaints received by Down Detector, the company was not present for any comment.
