Apart from the above which are the official apps which are approved by the prison, there isnt any other apps that will make calls cheaper or free. Other apps will mask your number via IP so that your calls are going through the internet and then straight to your phone via the app. Which again, makes calling a mobile for a prisoner at landline rates. But this method can be unreliable seen as you need good internet to be able to hear the prisoner properly. The audio quality can also not be the best. 

This is why we would recommend our package which divert the calls from a landline direct to your mobile phone so youll never miss a call again. You can sign up for our unlimited diverts package here: CLICK HERE then instead of a mobile call costing 16p for a prisoner it will be at the much reduced rate of a landline price saving the prisoner money. Whats more, you DONT actually need to download any prison call apps for our service to work!
