Why can t Japanese Sony phones be used in China?

The possible reasons why Japanese Sony mobile phones cannot be used in China are: the network standard of Japanese mobile phones is different from that of Chinese mobile phones; Problems with SIM card locks. The specific reasons are explained as follows:

Network standard: the reason for the network standard is only a small part of the Japanese mobile phone 4G network standard and Unicom Telecom FDD-LTE is the same, but it is completely different from mobile, Japanese mobile phones can not use mobile cards but can use Unicom or telecom cards.

SIM card lock: In Japan, mobile phones are customized by operators who can only contract with the identity of Japanese nationals, cheap but with SIM card locks, you can only use the card of the Japanese operator in the first six months after signing the contract, and you can apply for official unlocking with the operator after 6 months, and then you can use the mobile phone card of other national operators without affecting the function.

The reason why Japanese consumers abandoned Sony and Sharp in choosing the iPhone is mainly because of the system. In the era of feature phones, Japan's local mobile phone market has been very developed, and the related technology is relatively advanced, thanks to the super learning ability of the Japanese, and the mobile phone manufacturers continue to optimize for domestic consumers, so the Japanese feature phones at that time can be called the ultimate.

This leads to a unique ecosystem of Japanese phones, and more importantly, this system is customized for Japanese people, so it is relatively closed and very different from phones in other markets. However, this relatively closed ecology precisely meets the needs of the vast majority of Japanese consumers, so most Japanese consumers are not accustomed to or even reject the high-degree, open-source Android system.

Brief introduction. The closed-loop nature of the iOS system in the iPhone is exactly what Japanese consumers want, so it will be loved by Japanese consumers and occupy a leading position in the Japanese market. Of course, not only because of the system, but also because of the brand value and powerful performance of the Apple phone, which is also one of the reasons why Japanese consumers choose the iPhone.

After all, no chip can surpass the A series in terms of comprehensive strength.

Chinese phones can be used in Japan in two ways:

1.If you stay in Japan for a short time, you can buy a data card. Short-term stays can also directly open the roaming function of domestic mobile operators, directly call China Mobile or Telecom, and let customer service open roaming services in Japan, ** to be clear.

2.If you are staying in Japan for a long time, you will need a Japanese mobile number. Various carriers in Japan offer a lot of options, but three non-050 numbers are preferred, and it is best to have a mobile number in one step, because in the future many things will need to be tied to this number.

If you choose it, don't change it easily.

Extended Zen Liang Information:

1.People's Daily Online, Tokyo, December 23 (People**) Japan's Ministry of Internal Affairs and Communications officially decided on the 22nd that from May next year, major mobile phone operators will have to cancel the SIM card restrictions on mobile phones. This means that consumers can choose their mobile phone carrier more freely, but at the same time, once they change mobile phone carriers, the mobile phone may not work properly due to different communication specifications.

2.Mobile phones can only use SIM cards, while Japanese mobile phones are mostly lockable contract phones, that is, mobile phone operators cannot use SIM cards from other operators in their own products through special design. This is a way for mobile operators to avoid the loss of customers.

3.In response, Japan's three major mobile phone operators, NTT Docomo, KDDI (AU) and SoftBank (Softbank), said they would respect the new rules. At the same time, however, they said that "specific responses will be further discussed."

They weren't sure if the phones they were selling would work on other carriers' networks.

People's Daily Online-Japanese mobile phones are moving towards unlockless, and Japan will lift SIM card restrictions next year.

This is because the Japanese are looking for a more efficient pace of life. If you play with your phone, it will slow down the pace of their life.

Who told you that Japanese people don't use smartphones.

As a developed country, smartphones are now standard.

Why don't Japanese people like to use smartphones? Actually, this has a lot to do with Japan's electronic product technology, because we all know that Japan's electronic product technology is relatively closed. Many core technologies and innovation discoveries will not be opened to the public, let alone disclosed to the public.

Because Japan has its own unique industrial system, smartphones may not have a large market in Japan. In other words, smartphone sales in Japan are definitely low. So let's think of it this way.

If we can sell some flip phones in Japan, maybe we can make a lot of money. Because flip phones are perfect for Japanese people.

In addition to the above problems, in fact, many Japanese people are very different from people in other countries when it comes to using mobile phones. They think flip phones are more convenient to use, and this idea is so ingrained that they are largely reluctant to replace them. In fact, the flip phones they use now are also very different from our traditional concept of flip phones, and in our traditional impression, old-fashioned flip phones may have few features and the system is not very smooth.

But the flip phone in the hands of the Japanese must be very advanced and functionally no less powerful than a smartphone. Because the upgrade of mobile phones is still very fast, if there is no technological innovation, then the sales of the Japanese mobile phone market are likely to decline.
