How we help Prisoner and family support Prisoner and family FAQs How can I keep in touch with someone in prison? You can usually communicate via letter and some prisons will also allow outgoing phone calls, although these can be costly. We provide prisoners with international freepost envelopes so that they can stay in touch with friends and family without having to worry about the cost of stamps or stationery. There are sometimes restrictions around prisoners receiving items other than letters in the post. If you’re unsure of the rules, try checking the FCDO prisoner pack or ask us for advice. If you need help with getting your phone number approved by the prison or sending money for phone calls, please get in touch with us.
