If i send 1,500 texts per month i will pay
Moblie package - 30RMB calls per month - .08 RMB/text
30 + 1500*0.08 = 150RMB
Unicorn package - 20RMB calls per month - .10 RMB/text
20 + 1500*0.10 = 170RMB
Telecom package - 10 RMB calls per month- .12 RMB/text
10 + 1500*0.12 = 190RMB
Thus the cheapest is Mobile.
