WeChat Out gift cards can be shared, redeemed, and used between friends. Users can obtain a gift card by sending one to a friend or redeeming a received card. The amount on the card will be automatically added to the user's account balance for future use. When making calls, the gift card balance is used first by default.
Gift cards sent by friends are valid for a limited time, so it's important to use the balance before it expires. Any remaining balance will be deducted from the account balance upon expiration.
