2. The internet and social media
Prisoners aren’t allowed to access social networking websites (such as Facebook or Twitter) while they’re in custody.
You can’t email prisoners directly, but some prisons use a service called Email a Prisoner. If you send a message this way, it’ll be printed out and delivered by prison staff.
Each email costs 40p and you need to buy credit to use the service.
In some prisons, prisoners can also reply through Email a Prisoner. Contact the prison to find out if they allow this.
