How to open Unicom's 5-month traffic

If you are referring to the short message mode of 30MB traffic in 5 yuan, you can try to send the free short message "GPRS05" to 100 10 to subscribe to the 5 yuan GPRS traffic overlay package, because different provinces and cities have different opening modes. If you are unsuccessful, you can contact Unicom customer service or go to the business hall to find out.
