How to open 3G by SMS?

You need to activate 3G function (send SMS "KT3G" to 1000 1) or apply for 3G wireless broadband package (send SMS "KTWxKD"+package amount to1000/). Old users can upgrade their existing 2G packages through SMS, number 10000 and business hall. China Unicom also reminded that Unicom 3G will implement one-way charging, which is different from the one-way charging in the 2G era. Not only refers to the one-way charge when answering the phone locally, but also includes the one-way charge when answering the phone elsewhere. Similarly, take the 3G users of Sichuan Unicom as an example, whether in Beijing or Shanghai, the answers are free. The same is true for Unicom 3G users in other regions. This will be the first time that China will answer the off-site calls for free. Nowadays, many people often travel or go to other places for other reasons. During the trial commercial period, no matter where you are, it only takes 0. 18 yuan/minute to make any domestic calls, and all calls are free. Unicom, a 3G tariff, is obviously attractive to business people and fashion people.
