Mobile phones often receive text messages saying that there are 20 free text messages in the mailbox of 139. I don't know how to use them.

This complimentary SMS can only be entered into the email address of 139, and click "Send SMS" to use it. And sending short messages only supports sending to mobile phone numbers. If it is sent to Unicom or the telecom number is not counted, it will be charged according to the normal mobile SMS tariff. The charging standard for sending short messages using 139 mailbox is to deduct 20 short messages for you first, and then follow the normal mobile charging standard after exceeding 20. However, this email message writing function of 139 is really useful. I have used it for a long time. You can also try. I hope it helps you!
