South Carolina Gov. Telecommunications companies are opposed, saying jamming cell signals could set a bad precedent and interfere with legal cell users nearby. Last year, he took now-FCC Chairman Ajit Pai on a tour of a South Carolina prison to show him first-hand the benefit of technologies like jamming, which render cell signals useless.

In her letter, Williams gave other examples: A Tennessee inmate using a smuggled phone to upload child porn images; a North Carolina inmate calling in a hit on a prosecutor's father.
