So Li had to wait, until he learned on December 28 that the phone was unlocked again, and he got the information for a maintenance service center in Shenzhen, Guangdong Province.
"I didn't expect to meet so many uncertainties after I located it," said Li.
Kim said that retrieving a lost or stolen phone requires detective-like work.
"Unlike China, many other countries have a series of measures to ensure the rights of owners, including cell phone insurance and network blacklists," Kim said.
Additionally, the police aren't likely to help you unless you have solid information leading to the stolen phones.
Li sent the Tiananmen police station his invoice and warranty, which were later faxed to the Shenzhen police, who said the documents were not original ones and not legally valid.
Beijing police told Li that they would send someone to Shenzhen to get the iPhone back for him. For now, Li is waiting.
In the whole process of retrieving his cell phone, Li thinks Beijing police have helped a lot, but the Shenzhen police haven't been very efficient. "I even filed a few complaints to the police inspectors about it," said Li.
"If the police take it seriously and try hard enough, all the stolen iPhones can be retrieved," said Li.
"We are now cooperating with the Shanghai police," said Kim. "The police will bring us owners who report a loss, and we will provide information to trace the phones, which is a more efficient way," said Kim.
Booming business
Kim, whose major in college was network engineering, started this business at the end of September, based on his experience in finding his own lost iPhone. Kim has helped approximately 700 to 800 people retrieve their iPhones.
Kim told Metro Beijing that there is a major increase in customers asking for his services as well as other shops starting to offer similar services.
With their access to the ICCID a trade secret, Kim's business is booming. Kim has seven customer service staff members working 24 hours a day, seven days a week. The shop has made 160,000 yuan in the past few months.
Kim also plans to build a website in English in order to help foreigners wanting to use his services, too. Kim said a French man from Harbin recently purchased services from his shop.
But Kim has his concerns. "I am most worried that the thieves and the dealers may find some precautions against my method," said Kim.
