Prison Phone have been saving inmates at HMP Guys Marsh money on their calls from the prison to any UK mobile phone since 2013.

We do this by allocating a dedicated and secure local number to your mobile phone, this means when the inmate at Guys Marsh prison calls the new local number we have provided they will be charged at just the local landline rate (around 10p per minute) rather than the standard mobile rate (which is around 40p per minute).

This in turn helps to stretch the inmates PINS phone credit further and reduces the amount you need to send in for them to top up!
