At present, Unicom's 3G basic packages include 3G packages A, B and C, iPhone packages, prepaid packages, wireless network card packages and other packages, as well as various tariffs. However, if you usually use a lot of traffic, I suggest you consider Unicom's 3G-A series package, which is set for users with more Internet access and contains more Internet traffic. In addition, China Unicom's 3G basic package includes domestic call time and domestic traffic, so it can roam all over the country. In addition, since long-distance roaming charges the call time uniformly, the long-distance and roaming charges are no longer different. Specific tariffs can be found on Unicom's website.
