Description

From the listing uploaded by “appupdater”.

CorrLinks is a way for family and friends to electronically communicate with their loved ones incarcerated in institutions. Established through a relationship between a corrections agency and ATG, this system allows family and friends to subscribe to CorrLinks services. Currently all Federal Bureau of Prisons, US Navy Brig (Charleston and Miramar), and Department of Corrections (DOC) for the States of Iowa, Maine, Massachusetts, Nevada, and Wisconsin institutions allow such communication. Note: To use this app, you must have a paid Premier Account subscription. The app has the following features: • Stay in contact with your loved ones with real time alerts. Receive immediate push notifications to your device every time you receive a new message! • Eliminates login on a mobile device! • Messages downloaded significantly faster! • Messages previously read are in your inbox and don’t need to be downloaded again! • Retain messages on your device for 60 days – server still only keep 30 day. • Attach up to 3 mobile devices (iOS, Android) to your account! • Eliminates Captcha on the mobile app – making it much easier to interact. If you have issues with the app, please contact CorrLinks support at: https://www.corrlinks.com/Help.aspx
