Grandtime F25 4G LTE Android walkie-talkie network walkie-talkie smartphone Zello PTT radio enhanced antenna mobile phone

F25 is an innovative wireless communication device, a combination of Android smartphone and walkie-talkie. It works based on 4G WCDMA or Wifi to achieve unlimited call range so that users can keep in touch anytime, anywhere.

First, the user needs to insert a 4G SIM card as our regular mobile phone. The user can call any phone for personal use or urgent matters that the user needs to deal with.

Secondly, even if the screen is off, users need to install a PTT application (such as "Zello" or the user's own PTT application) to send voice messages to their partners through the PTT button. All information sent by the user will be recorded in the PTT application, so the user will not miss any important details needed. These functions are very suitable for patrols, police, factory administrators, school security, etc.

Third, the instant camera (dual camera) allows users to take any photos on the scene as evidence in the event of violence. Or the user is patrolling, the inspector only needs to send pictures to their partners to report the problem or ask for help through the PTT application.

Fourth, 3500mAh (lithium ion battery) is more suitable for law enforcement police, engineers and public safety and other fields.

Fifth, dual-mode GPS is more sensitive and accurate.
