Is there Unicom or Mobile in Nanyang, Henan?

From 3G alone, China Unicom uses the most mature and extensive WCDMA network in the world, with the fastest and most stable network speed and the strongest versatility in the world. In other words, the international version of custom machine of Unicom and many mobile phones is actually a logo and boot screen.

China Mobile uses TD-SCDMA network technology independently developed by China. Although it has strong autonomy, it is still in the development stage, and its maturity, stability, network speed and versatility have certain limitations.

CDMA2000 network technology used by China Telecom is the predecessor of WCDMA, and it is also a transitional development standard with some characteristics of WCDMA. Because of this, CDMA2000 is between the first two in the 3G services of the three major operators, and its network speed, stability and universality are slightly worse than WCDMA, but slightly better than TD-SCDMA.

So only look at 3G services, network speed: Unicom > Telecom > Mobile; Stability: Unicom > Telecom > Mobile; Global universality: Unicom > Telecom > Mobile.

You can log in to Unicom Business Hall for charge /3gindex/3gfee/A_plan.html to inquire about the details of all 3G packages (including 3G packages A, B, C, iPhone package, prepaid package, wireless network card package) such as calls, traffic, SMS and other package charges, as well as the standard charges outside the package.
