Internet use in prisons allows inmates to communicate with the outside. Much like the use of telephones in prisons, the use of the internet under supervision, for various purposes, is approved in 49 U.S. correctional systems and five Canadian provinces. Each of the reporting U.S. systems, except Hawaii, Iowa, Nebraska and Nevada, use computers to employ inmate educational programs, as do all five reporting provinces in Canada. There are 36 reporting U.S. systems to handle inmate health issues via telemedicine. However much like the use of mobile phones in prison, internet access without supervision, via a smartphone, is banned for all inmates.
