What is a short message card?

The so-called short message card is a short message discount card for users who have more short messages.

Operators often launch many preferential packages, and the packages with more short message discounts are the so-called short message cards.

If users have a great demand for short messages, they can choose to handle such a short message package.

However, now is the Internet age, using instant chat tools such as WeChat and QQ can get a better experience, and the cost is much cheaper than SMS.
