Is the pulse coupon for giving away the phone bill true or false?

Fake. Coupon can reduce the price of products, and it is a common commercial promotion tool for consumers. This kind of marketing short message is mass-sent, and it needs to be recharged after the coupon is issued, so the phone bill is not true. In the short term, there will be a discount on the donated items, but in the long run, the donated items will usually be distributed or received several months later.
