As the saying goes, once you enter telecommunications, it is as deep as the sea. Since then, mobile phones have been hard to sell. This is not a mockery, but a fact of the domestic telecom mobile phone market. It is understood that due to Qualcomm's absolute technical monopoly on CDMA, Qualcomm's telecom chips are at least 5 dollars more expensive than China Mobile Unicom's.
In addition to the high price of mobile phone chips in Qualcomm, the patent licensing fee is more expensive. Qualcomm's way of collecting patent fees can even be described as overlord clause, that is, each mobile phone should pay at least 5% of the retail price to Qualcomm.
Telecom phones have always been miserable. As long as you are a telecom mobile phone, you can't bypass Qualcomm. Even if you don't need Qualcomm's CPU, you should use Qualcomm's baseband. If Qualcomm's baseband is not used, other baseband will be indirectly paid to Qualcomm, because Qualcomm monopolizes the domestic 100% CDMA patent.
That's why even mobile phones with the same configuration, as long as they are telecom versions, are more expensive than other formats. The ex-factory price of a mobile phone is 2,000 yuan, and the telecom version usually costs 100 to several hundred yuan, which is the painstaking efforts of Qualcomm.
