At&t Preferential communication Fee

In February this year, the United States at&t a series of "unlimited phone calls to any phone" and "iphone subscribers" two preferential policies. According to the service called "Unlimited mobile phone call", the consumers who participate in the service can make unlimited free calls to any mobile phone users in the United States. To use this service, consumers must participate in one of the five at&t packages.　　Packages from 39.99 U.S. dollars a month to 109.99 U.S. dollars per month, to achieve unlimited SMS, personal package plus 20 dollars a month, family package plus 30 dollars a month. A AT&T spokesman said data traffic still needed to be charged. In addition, mobile phone calls to landline or landline phone also need to follow the previous pricing fees.　　At&t Mobile Chief marketing officer David Christopher said the wireless call package allows consumers to speak freely without paying attention to the time of the call. Industry analysts believe that the at&t investment is not very large, because voice traffic is gradually decreasing, and data traffic is increasing dramatically, so at&t still charge data traffic.　　The move is believed to be a at&t to retain customers and to counter the release of Verizon IPhone4. Meanwhile, At&t's iphone users received the following message: "At&t free SMS: You are a valuable at&t customer." We will give you a 1000-minute call to express our thanks. You do not have to pay any fees or take any responsibility. If accepted, please reply ' yes ' before March 31, 2011. ”
