Cell networks down nationwide: 911 services across America crash as AT&T, Verizon and T-Mobile customers from New York to LA report no service or connection with many phones displaying SOS messages

At&T, Verizon and T-Mobile users reported early Thursday that they are having network issues across the country.

The issue has left At&T iPhone users stuck in SOS mode, meaning users can only make calls to emergency services.

According to DownDetector, the increase in outages occurred around 4 a.m. Eastern Time. Service interruptions have been reported in New York, Boston, Washington, Atlanta, Houston, Dallas, Los Angeles, Seattle and San Francisco.

The major mobile phone companies have not yet commented on the cuts. It is not clear what is causing the problem.

Other smaller providers, including Boost Mobile, Consumer Cellular and Straight Talk, also reported similar outages.

In Erie, Pennsylvania, local 911 operators confirmed the outage, saying it had affected connections, reports TuErie.

WSB-TV in Atlanta reports that this is the second time in a week that Verizon customers in the region have experienced an outage.

In Orlando, the city’s Fox affiliate confirmed that its reporters on the ground were having trouble making contact. While in Tampa, some users said WFLA that their telephone service was cut off at 2 in the morning.

Customers in New Orleans reported that while calling was impossible, texting seemed to work.
