If you're looking to Download AT&T Enhanced PTT/ FirstNet RR on your Chromebook laptop Then read the following guideline.

AT&T Enhanced PTT & FirstNet Rapid Response To make your migration easy, we have made sure that FirstNet Rapid Response works with the existing AT&T Enhanced Push-to-Talk app, which is FirstNet Ready®. You’ll benefit from the MCPTT performance and features, with no need to download an additional application to your device. So there’s no learning curve. It’s time to enhance your PTT service with AT&T Enhanced Push-to-Talk. We’ve combined the best of both worlds. Enjoy the ability to communicate one-to-one or one-to-many just like a radio, while appreciating the convenience of a mobile phone. Track and share your location, establish geo-fences, send and receive highly secure messages including PDFs, pictures, and video, communicate with Land Mobile Radios, and take advantage of features based on 3GPP MCPTT standards, all powered by America’s best network*. New 3GPP MCPTT based features allow authorized users to place emergency calls and alerts, remotely disable and enable AT&T Enhanced Push-to-Talk and more. We also give you the option to choose from two intuitive user interfaces (UIs), basic or land mobile radio (LMR). Our basic UI is designed for all users and features. The LMR UI is designed for users migrating from two-way radios and mirrors the operation of a traditional two-way radio with pre-defined talkgroups and an all-in-one interface. To provide an optimal user experience, AT&T Enhanced Push-to-Talk is certified on a wide portfolio of devices, including both rugged and non-rugged smartphones, tablets and specialized devices.

AT&T Enhanced Push-to-Talk is available for a monthly subscription fee and includes seamless coverage across the U.S., Canada and Mexico without incurring mobile data roaming charges. International roaming outside North America is available as well and requires an international data plan. *Based on GWS OneScore Sept. 2018
