What is mobile phone cracking?

First of all, I want to explain why we need to lock it. Japanese mobile phones are very cheap locally, and operators earn customers' service fees. Therefore, if we buy mobile phones at a low price, their service fees will be gone, so we need to lock them. Program, that is to say, if you want to use a function of a mobile phone, you must connect to the operator's network, that is to say, you must have a Japanese mobile phone signal before you can use it, thus preventing the outflow of mobile phones. However, the domestic strongman has developed a card sticker, which is put under the sim card of a mobile phone and inserted into a Japanese mobile phone. The Japanese mobile phone can recognize it and pretend to be a Japanese mobile phone card, so that it can be turned on. However, many functions are still useless, so it is necessary to develop a stronger card sticker, and let the mobile phone think that the signal of China Mobile, for example, is the signal of a Japanese operator, so that it can use the functions of the mobile phone. Unfortunately, Sharp's mobile phone is now available except DoCoMo. . .

if you want to buy it, buy sh96i. Japanese machines can't have a Chinese system now, but they can send some commonly used Chinese characters, and the recognition rate of Chinese short messages is about 6%.

After you buy it, you need to use a card to stick it in China, and you can talk and send short messages, but the multimedia function depends on what machine you buy.

Sharp's machine doesn't support mp3, but Japanese mobile phones have strong copyright protection.
