T-Mobile has apparently restored service to its wireless network after being hit with a nationwide outage on Monday.
The complaints peaked Monday afternoon and had flattened out at around 1 a.m. Tuesday, according to downdetector.
Of the reported problems, 57% have been for phone, 32% for mobile internet and 9% for no signal.
The company quickly acknowledged the issue.
"Our engineers are working to resolve a voice and data issue that has been affecting customers around the country. We’re sorry for the inconvenience and hope to have this fixed shortly," Neville Ray, president of technology, tweeted Monday afternoon.
Social media users allege that there has been a distributed Denial of Service attack (DDoS), but that has been denied, according an article on Yahoo! Finance.
The Wall Street Journal reports that the FCC is opening a probe into the event.
One T-Mobile user writes: “They are overstraining 2g and 3g calling,” in a post on downdetector Tuesday afternoon.
Another writes: “I am from Quebradillas Puerto Rico and the entire island has no coverage, its not just in the United States.”
One more customer complains, “i just switched from Verizon on Saturday. T-Mobile outage all day yesterday. Today my calls and texts still not connecting. Please help now!! I may have to go back to Verizon!”
In a separate development, T-Mobile laid off several hundred Sprint employees on Monday afternoon, according to TechCrunch.
