Which cellphone plan are you using? I live in Shanghai, China. Now I'm using the China Telecom with my Iphone 5. The monthly cellphone plan at 98rmb(~$15) per month, which includes 400 MB data access on 3G data speed and 240 minutes talk. I guess the cost of cell phone plan is low compared with developed country. There are three main carrier service providers in China, China Mobile, China Unicom and China Telcom. All of them have good profit margin over the past few years due to emerging market demand. But in recent two years, the new subscriber acquisition slowed which has led to limited opportunities in growing business. In order to take subscribers from each other, some providers offered very competitive price. The competition drive the price down. I'm very curious which cell phone service vendor are you using and how is the price of cell phone plan in your country?
