The manufacturing giants of smartphones now focus on producing devices that are specially designed for the push-to-talk over cellular (PoC) technology. The innovations range from larger displays, battery back-up, and multi-media storage to enhanced communication devices and many more. Currently, various smartphone companies offer innovative technologies and characteristics to their customers. Besides, as people get involved with the use of cellular phones worldwide, the need for new technologies like smartphones has increased. Several public safety companies across the globe are utilizing push-to-talk solutions due to their innovative benefits and features. The devices designed for push-to-talk can bear with hazardous, stressful, and other situations. PTT ensures clear and instant communication by avoiding the disturbances with its half-duplex mode feature. The application provides instant access to the digital network over which an individual is working. Furthermore, the advent of 5G and other next-generation wireless networks would further boost the demand for the application. The applications of push-to-talk use 2G, 3G, 4G, and Wi-Fi technologies for efficient and undisturbed communications. Other than these, it can be used in use cases of public safety, manufacturing, transportation, and others. The PTT method is majorly used in air traffic telecom systems, cellular technologies, and police radios. The user is required to press a button on the device to shift to the half-duplex mode from the full-duplex mode, with which, one person can listen while the other talks. This mode is similar to a walkie-talkie, wherein, the communication between the operators takes place at different times. The push-to-talk (PTT) technology is a telecommunication method for two-way communication that utilizes the half-duplex mode.

Overall I would have to say that this phone was easy to activate using the Verizon web site, and especially with the help of the Verizon Tech, during the "test" phase. This time the phone was able to make and receive calls. The Verizon Tech had me use another phone to call him, and he held on while I removed the SIM card and put the phone back together, so he could run another test. They said that the SIM card that I had installed was for 4G, and therefore not compatible with this 3G phone. I found this out when I made the test call to Verizon by dialing #832. If you only need continental coverage the SIM card is not needed. I also borrowed a Verizon SIM card from one of my wife's old phone and plugged it in to the SIM card socket, but I found out later that you only need the SIM card if you need Global coverage. I bought an 8 GB SD card at Walmart for $7.88, and installed it. I opened the back with a coin and noticed that there was a place for a SIM card and a micro SD card.
