Why is Unicom cheaper than mobile?

It is not absolute that the mobile version is cheaper than the Unicom version. Generally speaking, the mobile version of the mobile phone with the same configuration is equivalent to the Unicom version, and some Unicom versions are also cheaper than the mobile version. Unicom needs to pay Qualcomm a patent fee for using WCDMA network, which will be relatively higher. Mobile uses TD network with self-made intellectual property rights, and its customized mobile phone patent fee is unnecessary. However, these differences are basically caused by domestic mobile phone manufacturers. After all, the state supports its own industry. If it is a foreign mobile phone manufacturer, the price is generally equivalent. Some models are even cheaper than the mobile version.
