Seeing that this phone can actually call the Soviet Union, it is not as simple as convenience. It's simply an artifact that can greatly improve the frequency and efficiency of people's contact. It's really like what Bao Zixuan said, you can be found in any corner of the world.

Bao Zixuan said: "It seems that Brazova lives in a happy family, and her father is a mechanical management engineer. His mother was a teacher, and his younger brother was admitted to the best universities in the USSR. I am also very good, and such a family is very beautiful in my opinion. ”

Brazova: "Thank you Mr. Bao for giving me this opportunity, if I really don't want to talk to my father on the phone for so long." The cost of each phone call from the United States to the Soviet Union was too high. ”

Bao Zixuan: "This is a small matter, and I want to thank you for giving us a chance to test the performance of the phone." If there is a friend who wants to call home and friends, we are choosing the last one. As for the future, you can only wait until the phone is launched to experience its features. ”

A middle-aged man walked onto the stage and said to Bao Zixuan: "I'm David Owen, a teacher at Oxford University in the UK, I want to call Oxford University, can I!"

Bao Zixuan: "Of course, I graduated from Oxford, but I didn't see you when I was studying, so I don't know you, I hope you don't be surprised." ”

David Owen: "I'm an electronics teacher, and you're an aeronautical power student. But I'm proud that Oxford has produced students like you. ”

After dialing the phone number of the Oxford University Electronics Lab, a female voice came from the other side and said, "Hello! This is David Owen's Lab!

David Owen: "Is it Shirley! I'm Professor David Owen, I'm calling you on my cell phone right now, mainly to test his performance, is your call clear!"

Shirley: "The call is clear, I can hear every word you say!"

David Irving: "That's good, I'll hang up." ”

Bao Zixuan said to Professor David Owen: "Professor Owen, how is the performance of our product!"

David Irving: "Great! I can't imagine there's such a convenient product in the world." ”

With the recognition of David Irving, an expert in electronics, the authority of the black cloud mobile phone has been confirmed. Bao Zixuan said: "The mobile phone demonstration has been completed, and the next step is the reporter's question session, where everyone can ask questions at will." ”

A young male reporter asked, "Hello, Mr. Bao, I would like to ask you how much this mobile phone sells!"

Bao Zixuan: "The Black Cloud phone is divided into two versions, and the men's unified black version is priced at $2,388 per unit. The women's color version requires special customization, so it costs $2,588 per unit. ”

Hearing that the women's version is more expensive than the men's version makes many men worry about their wallets. After all, if you use it yourself, if you don't buy one for your wife, it's definitely not good to be at home.

Another middle-aged reporter asked, "Hello Bao Sheng, where can I use this mobile phone now?" ”

Bao Zixuan: "We only opened seven cities in the first batch, six cities in the United States, Los Angeles, New York, Boston, Chicago, Atlanta and Detroit, and only one city in Asia, and that is Xiangjiang. ”

"These seven cities are now available to everyone, and the rest need to be opened up continuously. The upfront infrastructure investment is huge, and we need to build signal towers in each city, and we also look to work with local telephone companies. And then to achieve full coverage of the network, so that more people use the black cloud phone. ”

Then a beautiful reporter asked, "Hello, Mr. Bao, I would like to ask how much the construction of the mobile phone tower is and how much is the coverage." ”

Bao Zixuan: "There are two types of signal towers, one is the outdoor type. His price is $2 million, which can cover a radius of 20 kilometers, and the disadvantage is that the ability to penetrate walls is weak. One is the urban use type, which costs $300,000 per unit. It can cover a radius of 5 kilometers, and has a strong ability to penetrate walls, but the signal transmission distance is short. ”

At this time, the beauty always has some privileges, and the beauty reporter then asked: "What should we do if we want to contact this mobile phone?" ”

Bao Zixuan: "Our Heiyun mobile phone has two number segment modes, one can be installed by the phone company to install a fixed number for this mobile phone, similar to a car phone. The other is the phone card developed by Heiyun itself, as long as the number is distinguished, it can independently form another kind of number segment system, which needs to be selected by the telephone company, and can also be decided according to the needs of customers. ”

At this time, a reporter from Xiangjiang asked: "Bao Sheng, hello! I would like to ask what number and rank are now used in Xiangjiang Heiyun, and when can we buy them?" ”

Bao Zixuan: "In Xiangjiang, we Heiyun use a set of independent number segments, and there is a device at the terminal that can copy the number to the phone card through the computer, then this number is yours." ”

"Heiyun uses 11-digit phone numbers to distinguish the existing fixed number system. At present, there are mobile phones on sale in Heiyun stores in Xiangjiang. ”

"At the same time, the first batch of mobile phones has been distributed to the management of Black Cloud, the first is for testing, and the second is for popularizing mobile phone usage. Make our work more efficient. ”

Then another female reporter asked: "Hello, Mr. Bao, how can the signal tower form a network, and if I use a Xiangjiang phone number, can I use it in the United States?"

Bao Zixuan: "Signal towers can cover every corner of the city, and the telephone company can be connected to the landline telephone system when it operates, so that a larger network can be formed. ”

"Of course, Xiangjiang's phone number can be used in the United States, but the price is much higher. Because you're paying roaming charges to U.S. carriers. After all, this is a remote signal connection, and to put it bluntly, it is necessary to pay double the fee. ”

"For example, the price of a phone number in Xiangjiang is US$0.1 per minute when used in Xiangjiang, and it may cost US$0.2 per minute to use in the United States. Therefore, I do not recommend applying for a number in a different place, which will increase the cost of use. ”

Everyone was scrambling to ask Bao Zixuan all kinds of questions, and a reporter asked: "Hello, Mr. Bao, how can I prevent the thief from using the mobile phone after it is lost?" ”

Bao Zixuan: "At this time, you can contact the operator, and they will cancel your number." In this way, once the phone is sent out, it will be locked and cannot be used in the future. But you want me to help you find it, the current technology can't do it. ”

The reporter next to him asked: "Mr. Bao, hello! I would like to ask if this mobile phone can be used by linking satellites in places where there is no signal!"

Bao Zixuan: "Absolutely, provided that the satellite company agrees with you to access the signal." However, such a cost is not affordable for ordinary people, after all, the basic cost of satellite communication is very high. ”

"The black cloud phone supports multiple communication modes, and we have put a lot of effort into this. It is to let customers rest assured when using it, and they can easily and quickly contact the people you want to contact. ”

"There is one last question, just leave it to a beauty!" Seeing Bao Zixuan looking at herself, the beautiful reporter asked very happily: "Can this mobile phone be used for military purposes." ”

Bao Zixuan: "Theoretically, it can, but only if there are signal towers in the area where the warring parties are located. And the signal tower can still work normally, but I personally recommend not to use it in the military, military equipment is very anti-interference, and the black cloud mobile phone does not meet the requirements. All the chips and components we use are civilian products, and the strength is not up to the needs of the military. ”

Hearing that it cannot be used in the military aspect reassures the US intelligence agencies a lot. After all, this thing is really difficult to control after the military, and now these concerns have been eliminated, but further investigation is needed.
