A mobile app that can send emails to prisons has appeared in Russia. It can send not only text but also pictures. Russian media reported that this app allows people to communicate with prisoners through smartphones.
All letters will first go to the mailbox of the prison administration, and then be printed and sent to the cell. The prisoner's handwritten reply will be scanned and sent back to the sender's mailbox. Letters and photos will be delivered within one to three days, excluding holidays.

FSIN-Pismo is a website dedicated to sending emails to prisoners in watchhouses and labor camps.

According to statistics from the website developers, 115 institutions in 27 regions of Russia have joined the system. cell phone jammer

The system operator particularly emphasized that there is no size limit for letters, and there is no limit on the number of letters and replies per month.

Prisoners in prison should not lose social contact. Therefore, correspondence and legal telephone conversations are allowed. But private communication with the outside world is prohibited, so mobile phones are contraband in prison. Prison staff have long been vigilant to prevent mobile phones and SIM cards from entering prison institutions through various channels.
