Why do I need 20 cents to send a text message?

That depends on whether you have an early home card (local pass).

If yes, sending to the mobile network requires 0. 15 yuan/piece, while sending to users outside the network, such as Unicom and PHS, requires 0.2 yuan/piece.

It is recommended that you call 10086 to inquire about your package tariff standard.

Or if you are a customer of Xiamen Mobile, you can edit the short message "ZF" and send it to "10658621215", or you can check your local tariff standard! However, the SMS fee is calculated according to the normal sending network tariff standard.
