Hello, everyone. I'll answer your questions. What is double Netcom, what does double Netcom mean? Many people still don't know this. Now let's take a look and understand it!

Answer:

1, dual Netcom is to support two networks, such as China Mobile Unicom; full Netcom mobile phones support China Telecom, China Mobile, China Unicom six mobile communication standards, including TD-LTE, FDD-LTE, TD-SCDMA CDMA(EVDO, 2000), WCDMA, GSM(GPRS) six-mode single-card dual-card mobile phone terminal.

2. Introduction:

3. Features of full Netcom: one or two card slots, three network access, 4G optimization, five continents access;1 mobile phone supports more than five modules; or 1 or 2 card slots, random matching with operator mobile phone cards, avoiding signal blind spots, more secure;3 universal network, free choice of the most cost-effective operator package, more affordable; preferred 4G, its network easy to use, higher efficiency;5 continents roaming, universal, more convenient; In fact, due to the contractual binding relationship between users and a single operator, most users do not need to use real full Netcom mobile phones that support all standards and frequency bands globally; therefore, mobile phone manufacturers generally provide mobile phones with corresponding configurations according to the characteristics of regional markets and different customer groups, and generally do not fully cover all frequency bands in principle; For example, many mobile phone manufacturers, considering the small coverage of CDMA/EVDO network, launched five-mode ten-frequency quasi-full Netcom mobile phones dominated by China Mobile and China Unicom users; some manufacturers launched three-mode/four-mode mobile phones (GSM/TDS/TDD or GSM/TDS/TDD/FDD) accounting for 70% of the total number of mobile communication users; with the reduction of modes and frequency bands, the product cost of mobile phones is also reduced accordingly, and the price is more favorable. Different customers can choose according to their actual needs, users do not have to pay for unused features. Whether it is a full Netcom mobile phone is judged by whether the network standard and frequency band are complete. It must be based on the fact that both card slots can realize all functions, otherwise it completely deviates from the true meaning of full Netcom.

This is the end of this article, I hope it helps everyone.
