What is the charge for sending short messages with UC browser?

Uc browser is a short message sent by calling the function of the mobile phone itself, so it is the same as ordinary short message. Only software such as Fetion and Guest can send short messages only with gprs traffic, but Fetion is recommended. The user group is large and more stable. Generally, the information sent by other software will lag behind. I have tried Fetion, and the speed is similar to that of ordinary SMS, with almost no lag. Of course, this is also related to the network.
