Why is it so difficult to buy a telecom mobile phone without full netcom? I don't know if you have noticed that before the popularity of all-netcom mobile phones, many mobile phones did not support telecommunications. Let's see why it is so difficult to buy a telecom mobile phone without full netcom.
Why is it so difficult to buy 1 for telecom mobile phones without full netcom? In fact, the main reason is the patent issue. The technology used in telecommunications is CDMA technology. This technology is in the hands of Qualcomm. As a patent, of course, there is a patent fee. Therefore, mobile phone manufacturers should give Qualcomm patent fees when producing telecom mobile phones. Although the patent fee for not giving the mobile phone to Qualcomm is not very high, it is very high to sell millions to tens of millions of mobile phones a year. So this is also the reason why buying telecom mobile phones in the early years is more expensive than other versions. So we can know why the current dual-card mobile phone does not support two telecom cards. After all, two telecom cards have to pay two patent fees, and the cost doubles at once.
Some people may say that the current telecommunications is not as good as that after 4G, isn't CDMA no longer used? But don't forget, the 4G network is no longer needed, but the phone and SMS are still there, so if the telecom can't completely abandon Qualcomm, the mobile phone can only be treated differently.
Some people may ask, why are China Mobile and China Unicom different from Telecom? In fact, both China Mobile and China Unicom use the technology developed by our country. Although some of them are also based on patents in Qualcomm, after mutual authorization through negotiation, the patent fees will be very small. This is why China Mobile and China Unicom often support the same mobile phone at the same time.
However, the spring of telecommunications is actually coming, because with the advent of 5G, there is only one standard network left in China. At that time, telecommunications will not be treated differently.
Why is it so difficult to buy a telecom mobile phone without full netcom? In fact, the reason is related to the communication system; The current telecom 4G, like Unicom 4G, adopts FDD-LTE；; ; It seems that it is not difficult to realize dual card dual standby.
However, China Telecom's 4G is FDD-LTE, but 3G is CDMA2000 and 2G is CDMA. Due to technical limitations, it is necessary to support CDMA2000 and CDMA in order to realize calls and short messages in the state of 4G networking.
Naturally, then, the cost of mobile phones of Netcom is slightly higher than that of ordinary phones.
Huawei's nova 3e is not very high in configuration, but it is better than supporting full netcom. After all, compared with the other two operators, it is more affordable and scientific to use the Internet package of Telecom together.
Glory 10 GT, equipped with Kirin 970 CPU and 6+64GB memory, can be said to have relatively strong performance. Nowadays, popular mobile games are basically stress-free. And at this price, the cost performance is relatively high.
I always thought it was the author's personal hobby, and felt that electronic nudity had a unique aesthetic feeling; But when I saw the advent of Xiaomi 8 Exploratory Edition, I found that it was also in line with the aesthetics of the general public. Flagship Snapdragon 845CPU, 2k resolution full screen, these are the selling points on other mobile phones; However, here, it is just icing on the cake.
Finally, let's take a look at the works of Return of the Former King. Nokia, once known as "not following", finally compromised. The built-in mobile phone is a native Android system, simple and pure. The CPU is Snapdragon 636, which can only be said to be quite satisfactory; The cost performance is not very high, but this is what you can buy, real, feelings.
