Shanghai mobile phone tariff telecom, Unicom, which is cheaper?

Only Unicom's packages are divided into 2G and 3 G. Shanghai Mobile's 3G and 2G packages are exactly the same. Just put the original 2G SIM card into the 3G mobile phone and use the 3G service directly. The original package fee remains unchanged. There is no difference between Shanghai Telecom's 2G and 3G. New users are all 3G cards, and it depends entirely on whether their mobile phones support 3G. Specific to the package, the minimum package of Shanghai Unicom is the 36 yuan pure data package, and you must go to the business hall with your ID card. Details of Unicom 36 yuan Package Shanghai Mobile's minimum monthly rent package is Yitong Card package, and there is no monthly rent. The cheapest package is the standard card of Shenzhouxing, and the monthly rent is 8 yuan. Details: The cheapest SMS package is1M-Zone SMS package in 0 yuan. Details: The lowest monthly rent of Shanghai Telecom is 6 yuan Yitong Card Package. Details: the second is the Volkswagen bag. Details: Seeing this hard work, I suggest consulting Unicom customer service directly. 3G suggests using Unicom, which has large network coverage and good signal. I answered with great care, please add points.
