Does anyone know what the charging service for receiving SMS is like?

It is free to accept short messages sent by ordinary users, that is, ordinary short messages sent by users of China Mobile, China Unicom, China Netcom and China Telecom are free, and it is also free for mobile users to send MMS to your mobile users.

If you accept SMS or MMS from SP, this charge is free, but there are few free messages, which are generally charged. 0. 1 yuan/article charges very little, usually 0.5- 1 yuan/article, and some still 1.5 yuan, 2 yuan, 3 yuan and 5 yuan. There are many SP (information providers, such as code 3355, which is a veritable black boss, and no one has ever been hacked. I received its message before, and the result was deducted 10). Merchants and network operators (that is, China Unicom, China Mobile, China Netcom, and China Telecom) collude to hack consumer phone bills.

Some SP have a monthly subscription, usually 5-30 yuan/month. However, many SP have to accept 0.5 yuan's monthly fee. I advise you not to use this business.
