# (Mobile) Network Providers

There are 3 network providers in China.

China has 1.2 billion Internet users.

Assume that a user will pay phone bill of 5 yuan.

Then 400 million × 5 = 2 billion (2000000000)

So an network provider can earn at least "2 billion × 12 = 24 billion" every year.

I haven’t include the bandwidth fee yet. In fact, those users monthly rent is probabally more than 5 yuan a month.
