“Anybody that has some sort of dictatorship or leadership amongst the crowds,” said Mike, one of several prisoners who contacted The New York Times to publicize their strike. “We have to come together and set aside all differences, whites, blacks, those of us that are affiliated in gangs.”

Now, Mike said, every dormitory at participating prisons has at least one point man with a phone who can keep the other inmates in the loop.

Miguel, another prisoner at Smith who also declined to give his full name, estimated that about 10 percent of all inmates had phones.

“We text very frequently,” he said. “We try and keep up with what’s going on in the news and what’s going on at other facilities. Those are our voices.”

They are also a source of profit to the people providing the contraband. Miguel said he paid $400 for a phone that would have cost $20 on the street. Mike said he bought his through a guard. “That’s how a lot of us get our phones,” Mike said.

Inmates said guards had started confiscating the phones, and they complained that hot water and heat had been turned off. The Corrections Department placed several of the facilities where inmates planned to strike under indefinite lockdown on Thursday, according to local news reports.

“We’re hearing in the news they’re putting it down as we’re starting a riot, so they locked all the prison down,” said an inmate at Hays State Prison in Trion who refused to give his name. But, he said, “We locked ourselves down.”
