How to open the night traffic of Unicom?

According to different provinces, Unicom's night traffic packages use different packages and have different opening methods. For example, if you are a user in Guangdong, the traffic package is called idle time traffic, and 2G users have "2G idle time traffic superposition package", but the types and opening methods of 2G idle time traffic packages in Guangdong cities are slightly different. For example, Guangzhou Unicom's 2G idle traffic packets are divided into 5 yuan packet 1.5G and 10 yuan packet 5G:1.5G2. Open the 5G idle traffic 10 yuan package: send SMS 2GSYW 10 to100. Tips: The overlay package is only available in Guangdong Province from 0: 00 every day to 9: 00 the next day; When a free broadcast package is launched and it exceeds the traffic or is used during non-preferential periods, if the user package itself already contains traffic or other traffic packages are launched, it will be deducted from the package traffic first, and then charged by 1 yuan /M after the excess. For 3G users in Guangdong, you can send 3GSYW5 to 100 10 to open Guangdong 5 yuan Package 1.5G "3G Leisure Traffic Package", and the leisure time is 00: 00-9: 00, which exceeds the original package fee. For details, you can consult the Unicom customer service to which the number belongs.
