For several hours Wednesday, subscribers with several networks, notably AT&T and T-Mobile, reported being unable to download data or use their apps soon after the text alert, which was sent at 11:18 a.m. Pacific Time.
“The presidential text alert went out and after that I lost all internet, Gmail, apps — everything stopped working,” said Sarah Mendivel, a medical researcher at Seattle Children’s Hospital.
