(I copied it directly, so I won't say more! Share the good stuff! If you don't like it, don't complain, you'll know how to avoid it!)
As long as you are a China Unicom 3G user, you can send a text message to receive 500M of free nationwide 3G traffic during the event, not limited to local areas, not limited to roaming. For China Unicom 3G users, this is undoubtedly a super benefit. Without further ado, let's take a look at how to get China Unicom's 500M free 3G traffic during the Spring Festival.
How to get 500M China Unicom 3G traffic for free during the Spring Festival: Use your mobile phone to send the text message "WO 4G" to 10010.
The event period is from January 20th to January 30th. During this period, please send a text message as soon as possible to receive it for free.
Currently, some provinces can already send text messages and handle this service for free. In some provinces, it will be activated after January 20th.
This event is only available to China Unicom 3G users, and the free 500MB traffic can only be used between February 1st and February 28th, 2014. It will be automatically canceled when it expires! Friends who are interested, hurry up and get ready.
