Nowadays, everyone basically uses mobile phones for voice communication. It can be said that mobile phones have shortened the distance between us and improved work efficiency. However, making calls for a long time will also increase a certain amount of costs. Multi-person collaborative calls cannot communicate in time.
With the popularity of walkie-talkies, many people use walkie-talkies. The English name of walkie-talkies is two way radio. It is a two-way mobile communication tool. It can talk without any network support, and there is no call fee. It is applicable For relatively fixed and frequent calls.
Some time ago, I found a mobile phone that can insert a card into the national intercom and simulate FM short-distance calls. It is a dual-mode walkie-talkie.
The card insertion function of the dual-mode walkie-talkie is a by-product derived from the base station platform of the communication company. The advantage of the plug-in card intercom is that it has unlimited distance and national intercom. Due to the limitation of the environment, the analog FM walkie-talkie can only reach a communication distance of 1-5 kilometers, and the same is true for digital walkie-talkies.Also read:best long-range intercom
The card-plugged walkie-talkie breaks through the limitation of distance, as long as there is a network, it can make calls across the country, regardless of distance. The current all-netcom public network walkie-talkie uses 4G communication technology. Realize the full coverage of the national five-star kilometer network signal, no matter where you are, you can achieve easy and fast intercom.
Recently, the editor tried this dual-mode walkie-talkie of the Shengtuo brand, which has two functions of card insertion and simulation. It can not only insert the card for 5,000 kilometers of intercom, but also can tune the frequency of 1-5 kilometers to simulate the intercom.
From the appearance point of view, it adopts dual antennas to enhance the signal, and it is more convenient to operate the volume knob on and off. Equipped with a 2.0-inch small screen and digital buttons, this walkie-talkie is like a small mobile phone. But it has a five-inch speaker + 8k sound quality, and the sound is loud and clear!Also read:The best walkie talkie for long distance of 2022
In addition, he also has a large-capacity battery of 8500 mAh. TYPE-C usb charging is simply not too convenient. At the same time, it supports group calls, individual calls, and the function of gathering speeches, member names, group name modification, and platform scheduling functions. China's 5000km call independent management platform does not matter. Whether it is business or construction site engineering, logistics fleet, travel, self-driving tour, it can be easily controlled~
This walkie-talkie comes with its own card, and the most important thing is to have a quality inspection certificate, which is properly trustworthy. In addition, it includes lifetime call charges and lifetime platform usage fees, whether it is worth it or not is up to you!
