The initial signs are positive: China Mobile, which has the world's biggest network of mobile phone users, told CNBC this week that it had received 1.2 million pre-orders for iPhones.
The iPhone also goes on sale during a key gift-giving season with Chinese New Year just around the corner.
In a sign of just how important the deal with China Mobile is, Apple CEO Tim Cook has been in Beijing this week.
On Friday, Cook and China Mobile Chairman Xi Guohua were at China Mobile's flagship store in Beijing where a small group of customers received signed iPhones and posed for pictures.

Analysts say they are watching how users respond to the packages offered by China Mobile as this is likely to be key to the success of the Apple-China Mobile deal unveiled less than a month ago.
"Most of these [smartphones] are packaged with two-year plans and what we're seeing, at least in the initial indications from China Mobile, is that they are packaging significant amounts of data with their 4G network," Chris Lane, senior research analyst at Sanford C. Bernstein in Hong Kong said.
"Now that's important because with 4G, you use more data. So if you're a customer and you're looking at buying an iPhone from (China) Unicom, (China) Telecom or (China) Mobile, it's not just about the device and the price, it's about network speed and the total cost of the data you're going to use," he added.
Chinese regulators last month granted wireless licenses to the three big Chinese carries, removing a key stumbling block to a deal between China Mobile and Apple.
China Mobile has an estimated 760 million subscribers on its network, while China Unicom and China Telecom have around 280 million and 185 million users respectively.
China Mobile shares rose 0.8 percent in Hong Kong on Fridayto their highest level in over a week.
Still, Apple, which has wooed consumers around the world with its iPhone, faces stiff competition from Chinese rivals as well as South Korean tech giant Samsung which has made significant inroads into the smartphone market in recent years.
According to research firm Canalys, Samsung had a 21 percent share of the China smartphone market in the third quarter of last year, while Apple held fifth place with a 6 percent share.
"Apple is under pressure, yes they have great products but markets are saturated and so they will have a difficult time growing," Andy Hargreaves, senior research analyst at Pacific Crest Securities told CNBC on Wednesday. "The reality is that not everyone can afford an iPhone."
