What networks can Dalian Meilin Park use?

I am here in Shuangxin Garden, and I use Unicom. One trillion, 900 a year, one for each family, 780 after discount. Free fixed line delivery for one hour. In fact, it is equivalent to the monthly rent in 20 yuan, and an hour's phone call is enough. The excess is charged at 30 cents per minute.

Two megabytes should be 1200.
