Questions about mobile packages

Well ... the packaging is different in different places. I used to travel around China in Shaoguan, Guangdong. Na Yue rent 18, free. It only costs ten cents to make a local call! But now I am in Yangzhou, Jiangsu, and I wonder if this friend is in Jiangsu. I have seen all the packages of China Mobile Unicom. I feel that the dynamic online chat package is not bad, the monthly rent is 20, free, including 200 messages on the network, and more importantly, 50 megabytes of internet traffic, so there is no need to open a GPRS package. The disadvantage is that 20 cents for local calls (actually not expensive) add up to 25 per month, which feels very valuable, including a lot! But you don't know if there is such a card in your city. General business hall will have a package fee, choose what you like!
