cell phone jammer is widely used in all kinds of areas

Dopod C575, P800W, etc., as well as the NOKIA 6680, N70, N72, N73 , N95, Sony Ericsson K750, W810, K800, etc., Siemens has several, including EF61 and so on. Q & friends above the EF61 is what he bought, I can say for sure, if it is to buy it this year or last year, will be refurbished machine no doubt. You will definitely need this kind of cell phone jammer during an important meeting.Because EF61 I remember like 06 there, and now definitely discontinued, the so-called parallel imports is absolutely foreign deceive, and must be refurbished machine no doubt. Having said that, even in 2006, when Siemens refurbished machine is the largest. Shenzhen Huaqiang North, the man called to do through the world market, is the largest market for refurbished machines, refurbished machines and cheap there, but also the warranty, (note that there are instructions refurbished machine, and does not sell refurbished machines as new machines ) Interested friends can go there walk to see, I did not go a long time, I do not know what the situation.
 cell phone jammer  can nonstop work for 12 hours.I do not know which lines of others tampering, said a word, "If you like a person, let him go to Shenzhen, where is heaven; if you hate a person, let him go to Shenzhen, where is hell." Yes, there are viable for people with vision, opportunity is everywhere in Shenzhen, Shenzhen's electronics industry chain is very mature. For the average person, just be able to Shenzhen's high prices were crushed to death. After 12 hours,  cell phone jammer needs to be turned off for 20 minutes.On the phone, Huaqiang North, where a large group of people to feed. Yuan Wang Digital City, a small, one-day cash flow as high as two million, reportedly the largest of the parallel distribution center in Asia. I remember in 2006 when, for some time, the Shenzhen municipal government can not stand the pressure of the domestic mobile phone manufacturers (At that time, many mobile phone manufacturers say they are parallel and black cell phone and made no way out), joint customs, business, reporters and other sector, to take joint action in combating parallel that Huaqiang North, to see the counter on the check, take the package to be stopped to check the purchase, operation lasted about two weeks as a result, all transactions move afar off, and all are in after 7 pm, next to the original Yuan Wang Digital City, the rental immediately soared. After 20 minutes,  cell phone jammer  can be switched on again.Operation lasted two weeks, just as a gust of wind like a retreat, all the situation remains. Later checked several times, also very little effect. I think the parallel has formed a complete industrial chain. Huaqiang North, where the logistics (courier companies, post offices, etc.), source of most of its business is courier phone. Next to that rent, and living by this, it is difficult to calculate how many people. I know there is one, Huaqiang North, rent, shop in Taobao, the peak time every day to sell dozens of parallel phone. If you completely blow parallel industry, how many people will not eat, how much how much consumers spend more money to buy expensive phones? Then  cell phone jammer can work well for another 12 hours.
