Google spent 20 days at home SIM card, all people every day ask & ldquo; Why China Mobile and Unicom can not. & Rdquo;
In this operator's called Project Fi do buy a mobile phone number, in the same screen no more than three pages of options to follow step by step setting information to fill orders. You do not have front and Jingdong as large websites to find their desired function.
Fi set menu, $ 20 package all calls, text messages; traffic per GB $ 10 discount used up by the end of the return.
Open Fi application is automatically generated using the flow chart showing the flow for every day. You do not wait for a monthly bill, dense above four to five rows of & ldquo; GPRS Listing & rdquo ;.
In the United States cities, fitted Fi phone will automatically connect to public Wi-Fi to save traffic. You do not have to open the Wi-Fi settings to see nearby No special operator's network, and then enter the user name and password.
Fi pricing, only two numbers:
$ 20 a month package of calls and text messages, mandatory;
$ 10 per GB data traffic count, custom.
By the end, it will not flow out of the pro rata refund to the bank account. You do not think of this month left a 500MB, valid for long.
Commonly used numbers are too many harassing phone calls eyeing, you can directly contact customer service change number, you do not need to change SIM card.
The most outrageous is likely to return to China, Fi does not recommend that you turn off the network to avoid high roaming charges, but suggested that the & ldquo; Welcome to China & rdquo ;. It charges:
Flow of $ 10 1GB, and a US price, according to the specific amount of charge;
SMS for free;
Wi-Fi phones under 6 minutes to play Chinese yuan per minute, non-Wi-Fi 1.2 yuan per minute.
This morning, Google announced the adjustment of overseas network speed, future Fi speeds abroad is no longer restricted to 256kbps into 3-5 Mbps. Not too fast, but the international roaming rate.
Fi obvious drawback is that it can only be used three Nexus phones (Nexus 5X, Nexus 6, Nexus 6P). If you use in China, the biggest problem is that the United States must be inserted in the SIM card to activate the number.
On-line just a year, Google House Project Fi has evolved from a need to invite registered test products, operators can evolve into future global use.
Project Fi and other operators What is the difference
Google Fi is simply the virtual operator services. The so-called virtual operator, is the lease that large network operators, wholesale traffic and resources, repackaging selling small & ldquo; carriers & rdquo ;. They do not build base stations, basically does not control equipment and technology, so called & ldquo; & rdquo ;. virtual operators
And all of the virtual operators, like, Fi services through all major carriers and conducted in cooperation.
The United States has four nationwide carriers, Verizon, AT & amp; T, T-Mobile, Sprint.
Google and the relatively poor performance of the two, Sprint and T-Mobile signed a cooperation agreement, signed last month, and in addition a relatively small regional carriers U.S. Cellular.
Virtual operators are generally small companies, to do some major operators despise small business. For example, AT & amp; T requires users to buy a mobile phone to their own network from there, although the phone discounts, but the monthly cost is also high. But the virtual operators is another one way, such as lease AT & amp; main business of virtual operators T network H2O is to buy short-term package that comes with the phone to the traveler does not require network.
But Google is not the same, its market value is higher than the four major US carriers combined. Fi tariff are very competitive:
Price comparison, only you use 6GB monthly traffic, traditional carriers will be more expensive than Fi.
Moreover, although Google Fi package is a fixed cost, but if you do not use up your monthly package in traffic, extra money will be returned to you in equal proportions.
Fi is free to use in 135 countries, from July 13 began in overseas roaming network downlink speed to the 4G level. Unless only 2G network, no one operator's traffic more than 10 times more expensive than Fi.
Behind the price difference is Fi technology.
Fi is driven by software operators
Currently, Project Fi co-operators have three: Sprint, T-Mobile and U.S. Cellular. U.S. Cellular and Sprint's CDMA 3G network and LTE; T-Mobile to WCDMA 3G and LTE.
All three operators are not Verizon and AT & amp; T so much. And China is different, even though the nation's largest carrier China Mobile network coverage has not so perfect.
Verizon 4G coverage
AT & amp; T 4G coverage
T-Mobile 4G coverage
Sprint 4G coverage
US Cellular 4G coverage
These are the five carriers covering the US 4G network, namely Verizon, AT & amp; T, T-Mobile, Sprint and US Cellular.
Virtual operators can switch to a different carrier networks based on the signal strength of your own rent.
Google Project Fi technical director Dr. Liu Junda to "curiosity Daily" said, Project Fi only can automatically switch network, and can be maintained when switching the call is not interrupted.
And general SIM cards of different operators, Project Fi requires the activation of the SIM card currently produced in the official Nexus phone. The reason is that, Google the carrier's network configuration files built into version 5.0 of Android after years, became a part of the system, rather than the built-in SIM card.
This phone switch to a different network than the traditional SIM card faster.
At the same time, Google and mobile phone baseband chip manufacturers, for example, and Nexus series baseband provider Qualcomm collaboration can dynamically switch network configuration. According to Google's argument, the original handover LTE, CDMA networks need two minutes to find and register, now takes only 10 seconds.
There is a less public approach Fi overseas use. At present, even if you turn off the phone system roaming options, it can also be used in most countries, and the United States the same data rates.
Fi all traffic generated during this period through a dedicated VPN encryption. In other words, even after the other operator's network, your phone's data will not be accessed carriers.
Google has search business to make money, traffic on the phone it seems very care about. Fi In addition to switching in a mobile network, but also to switch to a public Wi-Fi up.
This is not the first time Google business operators
Google's first attempt carrier business is Google Voice & mdash; & mdash; a Skype and similar Internet phone, but it can bind phone number.
Early Google Voice main function is to give you a virtual number, so you can use more than one number on a cell phone.
After 2014, Google Voice, and online chat applications Google Talk is integrated into the Google Hangouts, the function Hangouts app includes a mobile phone network and Internet phone calls, send text messages and online chat function.
Google Voice can be seen Fi predecessor, now you're Fi activated, the system will ask you not to use the old Google Voice number, open the web version of Google Hangouts, call the default phone also has become a Google Fi.
Google is another basic service operators wired broadband Google Fiber. Google Fiber Google is building their own broadband cable network in 2012, the first landing in Kansas City.
Google Fiber offers 1Gbps symmetrical download and upload bandwidth speed broadband. Launched at the beginning of 2012, Fiber not have to pay construction costs, requires only a monthly fee of $ 50 will be able to use high-speed broadband of 1Gbps, low-speed broadband more common is free.
Google Fiber bandwidth and exaggerated prices stimulated other US carriers. After that, Comcast also introduced a 1GB bandwidth broadband, Time Warner and AT & amp; T have successively raised its broadband access speeds.
But the development speed is not fast Fiber, starting in 2012 so far, it is only in the United States to enter the six cities.
Has been relying on services to the city, Fiber is said to have received a good income, the second company to become profitable Alphabet service (the first is Google itself).
Scratch digging, laying fiber-optic time-consuming. Although Google has acquired a number of small operators, but progress is still very slow Fiber.
Fi learned the lessons of Google Voice and Fiber
Google Fi is & ldquo; & rdquo ;, virtual operator does not require the construction of a base station. By and large operators, doing business very quickly.
Google and strategic operators is also very clear, and got most operators are short of money.
And it did not directly undercut traditional carriers.
Fi launched in 2015, by invitation to register. Until March of this year, Fi only open for sale to the United States, but the user can only activate it on three Nexus phones. Google apparently did not want to do too much to stimulate other operators compromise.
Fi also get rid of Google Voice is too complex, everything you need on site to solve the problem. As everyone can use a service, Fi use no threshold. Google will send you a SIM card, just like the normal use of mobile phones that can be activated.
Change packages, suspended, etc. operations are very simple, in the mobile application can be easily completed. If you encounter any complex operations, such as the replacement number, Google customer service will call you directly to solve the problem.
Google does not lack the power to engage in infrastructure
As a pure Internet company, Google has been the tradition touches the construction of infrastructure.
After the Internet bubble burst in 2000, Google from the closure of a large number of Internet companies to buy a lot of the hands of low-cost cable, servers, building their own server center. Google is the first to establish their own exclusive computing center Internet companies.
Google is the first Internet company to design their own server hardware company. Most Internet companies have to buy from Dell, HP, IBM servers there, but Google has become Intel's major customers, the bulk purchase of processor, so Shuo foundries and in accordance with their standard production server.
Today, traditional carriers now the business is not good:
These are the comparison Google and other American four operators performance.
Cost one hundred billion built 4G network, games, videos, music, ads generate significant revenues on the phone. But these Internet companies are basically the money earned to go, operators earned only traffic charges.
Investment earn money directly affects the rate of investment in the future operator of the network. 5G network is currently not seen even the shadow.
But Google can make money from the popularity of the Internet in. The more users regardless of traffic and more money.
Facebook is also the company's advertising feel the same way. It launched OpenCellular open-source hardware platform this month. In the vision of Facebook, this box can provide a low-cost base stations 2G, LTE, Wi-Fi and other networks, users can use to send text messages, phone calls, and the use of network services.
Historically, Google to develop a new business, like most of the routine is to directly buy one. Phone system (Android), video (YouTube), intelligent home (Nest) and even advertising systems are made up after the acquisition.
Google Fi development is also very fast. April 2015 began small-scale trial, and today has been extended to three co-operators, to provide high-speed services to the world.
If the traditional carriers can not promote infrastructure evolution, relying more mature Fi, a decline to buy a new operator to enter the market, it is not too difficult to imagine things.
