I received a text message from China Unicom offering local traffic monthly packages at a 10% discount. Is this true or false?

Nowadays, China Unicom carries out many data discount activities. For example, in Shanxi Province: the original price is 100 yuan for a half-year package of 1.5G intra-provincial traffic, but now it is 10 yuan for a half-year package of 1.5G intra-provincial traffic at a 10% discount. If you are not sure whether it is a China Unicom company activity, it is recommended that you directly call the customer service 10010 of your home location for verification.
