When I first arrived in the United States, I was always distressed by what mobile operators I chose. When I first came to Taobao, I bought H2O for 30 months, unlimited US domestic calls, 500MB of traffic, and the traffic was really stretched. I then switched to AT&T, 45. Knife for a month, unlimited domestic calls, 3GB traffic, traffic is almost enough, but it feels too expensive, so I have been watching posts on the Internet, to see how people say, recently tried to install Google Fiber's fiber service, no intention of discovering Google Project fi, generally Google's products, always have a strong Google Fan, that is not to be mediocre, after I learn about Project fi, I found that Google dared to take the lead for the world and successfully started. The so-called Google Project fi is a virtual operator in the United States. There are four major operators in the US, Verizon, AT&T, Sprint, and T-mobile, and the virtual operators are numerous. Because the US virtual operators started earlier and have policies. Support, so the level of development completed in mainland China, they provide more detailed and more varied package options than the mainstream operators, often the price will be lower. Google entered the virtual operator market in 2015. The market has already developed to this point. Google will certainly not stop at the predecessors' perception. Google has used its strong influence to persuade T-Mobile and Sprint to form a new Project fi. Provides web services and opens its global wifi hotspot, accessible only to Nexus and Pixel devices. As for why there are only a few Nexus and Pixel mobile phones supporting Project fi, I will continue to talk about it later. Because it involves the automatic switching of operators' networks and the automatic joining of wifi hotspots, especially Google has solved the technical problems of switching operators seamlessly during the call, so the call effect is very good, and the wifi call is also completely free of problems. Use in cities can significantly reduce traffic usage. Seriously looking at the classmates will certainly say, not to say that attacking nexus and pixel devices to visit you, how do you iphone this is the signal of fi, secretly tell you, iphone also received a call text message is completely no problem, this is why I choose fi one important reason. And the signal is better than ordinary AT&T and T-Mobile, and the coverage is also very wide. Since it is a phone operator, there must be a package, the following system describes in detail his three points. First, mandatory service, $20/month, unlimited calls throughout the United States. Optional service $10/Gb, one price worldwide. Simply saying that this $20 one-month unlimited call text message has completed the explosion of China Unicom Telecom, and can also use the two operators' networks and hotspots at the same time, nexues and pixels can automatically switch to which signal strength. Second, the global flow of a price so hang things out of the Google dry out, not only that, Google also let the monthly flow of data completely become history, if you plan to pay 2Gb monthly subscription, you pay 20 dollars, but you use the end of month settlement With 1.2Gb, Google will immediately refund you $8. If you use 2.3Gb, then you only need to pay $3 more. This is how I use the experience of about ten days. I have not deliberately saved traffic. I have seen beautiful scenery. I have used 0.58G traffic for ten days. I feel ok. Sometimes I go to some shopping malls and find that the iPhone is automatically connected. WiFi, but I can't remember if it was connected before. The reason why this matter is mentioned separately is because the function of automatically connecting wifi is a function that project fi and nexues have. Do not know whether Google is ready to open this feature to other mobile phone users. The hardware, software, and corporate strategy involved is too complex. This is no longer a specific discussion, but it is hoped that this service will be more extensive. Maybe the mobile phone will no longer be available in the future. The card can be used to switch any operator in real time and only need to pay a bill, which is divided into settlement by operators, technology development, market selection, and may be realized in the United States soon. Number portability in the United States has grown to something that can be done in ten minutes. Simply fill in the accout number and pin and click transfer. Restart the phone and notice that the signal flag has changed. In China and Great China, after the start of the launching of the No. Turning Network in four places, I had the privilege of becoming the first group of users who turned to the Internet. After a happy network transfer, I discovered that it was too CNM. Text messages and bank notices were all lost. Calling the bank's customer service and Alipay customer service were all told that they could not solve the problem. The operators pushed the 625 and they had no problems. It may be the problem of the bank and Alipay. Let me To find them, the two sides pushed and pushed, and finally my problem! The key is that you can't go back at all. Consumers have been played by the three major operators and they have never dared to mention the transfer. It is also quite expecting that the iPhone 8 virtual SIM card can enter China's little buddies. Don't dream and change the country to play. Just on the second day when I activated fi, fi launched the home plan, and the added family could offer $5 off. $15 US, Canada, Mexico, and other unlimited SMS calls, I feel really good. Fi official website is currently engaged in activities, can offer $150 discount to buy nexus5x, because the card needs to be activated, the iPhone is definitely not OK, other Android machines I did not try to pass it, I bought a nexus 5x32 GB for the sake of safety, buy with fi , and activate the use of fi, then the price of 199 US dollars 16GB, 249 US dollars 32GB. Note that if you have a discounted price, you have to use the phone to activate the fi. If the phone is not activated within 30 days, it will deduct more than 150 US dollars. This is a home-purchased version of the nexus5x for the Google Store, which is now discontinued in the Google Store, but if you purchased it from fi.google.com, the Google Store order will still show that you have purchased nexus5x. It is said that while the Store has been unloaded from the old product, it is still being sold on other official channels. Just arrived, a mobile phone card and a mobile phone. LG production Instructions, chargers, fuselage and other old routines To be honest, Zuo Gong has been very good, but he still does not have the feeling of a firm and stable iPhone. Start up and insert a fi SIM card. Boot, select language Download the latest update The charger works well. Both ends of the cable are USB Typec Ready to boot Automatically display welcome to project Activate fi The mobile phone only took one day. The system experience is still somewhat different than the iphone. However, Google Now has occupied the market's commanding heights. Of course, this powerful function of hanging heavens is only done by Google with powerful integration capabilities. Nexues and pixel phones are Google Now’s most complete experience. The Google Now service is Google's acquisition and organization of all Google services that you use, and then intelligently generating task reminders and suggestions. For example, if you receive an itinerary for your ticket in gmail, Google Now will tell you when you want to leave to catch up with the plane according to traffic conditions. Flight information, traffic information, etc. will be displayed on the Google Now card. It is very smart. It is undeniable that the lack of a full set of Google services, especially Google Play in the Chinese market, completely disrupts the overall experience of Android phones. Although it gives some domestic application market opportunities for development, it is a glimpse of glimpses. Google services will return sooner or later, no matter what The way will eventually lead to unification. Completing actication is in fact the process of portability. The card can be connected to the cellular network instantly. Since I was operating at more than ten o'clock in the evening, the fi service told me that tomorrow morning was needed to complete the transfer process and get the phone signal, but actually it did not arrive. The 12 o'clock transfer has been successful. I used the landline to dial my own number and found that it was connected via the fi sim card. The fi statement mentioned that the normal transfer time is from 2 minutes to 2 days, and the United States has been developing to a point where it is so convenient. It is definitely worth thinking about. We can't always think of using the system to keep people in check, but to use services to retain people's hearts. This is not only worth thinking about by the three major operators, but also worth thinking about organizations that are trying to control everything. Since ancient times, we have won the hearts of the public and do not touch the stone again. Please walk the bridge. Finally, it must be mentioned that fi is used on the iPhone and not officially approved by Google. However, the government also explicitly forbids and opposes consumers to use fi on the iPhone. I used the experience of more than half a month to play on the iPhone. Telephone Internet access is normal. The only problem is that the text messages received will be accompanied by a string of strange codes. As shown in the figure, fortunately, normal use is not affected, and in addition to verification information and advertisements, basically no SMS messages are received. The most problem I do not know you encountered, I started out after the iphone7 iphone7 128G black. Later there was a time to help a friend to buy a mobile phone in the process of boring, the sudden development of the brightness of the display is much higher than the brightness of my phone I asked the Apple store's staff, they said it was a setup problem, but they designed five minutes or found that my screen was dark. No way they helped me about the Genuine bar, Genuine bars checked a tell me that the screen is not The problem is that there is a problem with my Bluetooth. I said that I use Bluetooth to listen to songs well. They have problems with Bluetooth hardware and can help me change machines for free. Then I used a second new iphone7. After using it for a week, I'm going to the apple store to help my friend to buy things. I've compared my iphone7 to be even darker than the display. I just wanted to find them. Who knows when it came to me? Let's talk about the mobile phone, Apple Store must be forced to install Apple Pay, but then tried four times in the sizzling sound failed, there is my check to the Genuine bar to do a check, a check is a Bluetooth fault again To give me a replacement, I said that I have changed this one time, the last time is the Bluetooth problem, why is the problem of Bluetooth, Genuines employees say we do not know why, because it is Bluetooth fault can be changed for new machines, you want No, since there is a problem, I will use a new mobile phone. Within a month from the launch of the new machine, I have already used three new machines. I don't know if you have met any friends or not. Have been able to try to pay for the apple pay to see if there are problems, I very much doubt that a batch of iPhone problems, or not so clever two failures have occurred to me.

Third, because there are not many domestic friends in the United States, international calls have become the issue of greatest concern to me. Calling China from the United States will cost one minute for one minute, that is, ten dollars and one thousand for 1,000 minutes. This is the price of the international long-distance call. The cost of domestic local calls. 
Phone is a size, nano sim 
Cable texture is good. 
Post fingerprint. 
The photo effect is overall good, if you do not want to spend a few hundred knives to buy iphone, nexus5x and nexus 6p are good choices.
