The key point is that, based on Qualcomm's monopoly position on CDMA chips, the entrance fee of CDMA in Qualcomm is as high as1-2 million dollars, and the entrance fee is non-refundable, and the patent fee is paid to Qualcomm for every mobile phone sold. Moreover, Qualcomm's CDMA scheme is deeply tied with the Bluetooth technology of RFMD and the WIFi chip of ATHEROS, and the API is specially opened for this purpose. Qualcomm took half the profits from a mobile phone.
In fact, this is the key reason why there are few good terminals under the current CDMA network standard! ! ! "

Simply put, it is mainly because of patent fees and entry fees. Usually, in the same model and brand mobile phone, the telecom version will be about 500 to 1000 yuan higher than the ordinary version. The only difference is Xiaomi mobile phone, which announced that it does not rely on hardware to make money. Both the telecom version and the regular version are 1999 yuan.
It will be released in mid-March. I'm using WCDMA version now, and I'm going to open the telecom version again. I have taken the reservation number at present.
