How much traffic does Fetion send a short message, how to calculate the bytes, how to charge,

Hello, if you are a customer of Beijing Mobile, when you log in to Fetion client, the number of characters sent will be determined by the uplink and downlink usage of your mobile phone. Namely: 1M= 1024KB, 1KB= 1024 bytes =5 12 Chinese characters. It depends on everyone's usage. You can edit the short message "CXYL" locally and send it to 10086 to inquire about the remaining free resources in the package. Thank you for your support to China Mobile, and wish you a happy life!
