What preferential phone plans does China Unicom offer? Should I surf the Internet more, make less phone calls, and send more text messages? Please recommend

According to your request, I would like to recommend China Unicom’s 66A 3G package to you. This is the only one among China Unicom’s three types of packages that includes text messages.
