How much does it cost to send a short message to Southeast Asian countries in China?

I have used mobile and Unicom cards, both of which are 1 yuan. I heard that there is also a reward of fifty cents.

But I don't know what package is cheap to send a message. You can ask at the local service desk.

Mobile phones can send and receive information freely, and they can also answer calls from abroad. That is, if you want to make calls abroad, you have to open international business services and pay a deposit. The deposit fee varies by region and service desk.
