Can I send a free SMS to the mobile 139 mailbox on my mobile phone?

Sure! You must set up a newsletter first. You must enter the email address in the address book and enter the correct format! Then go back to the personal address book and click the menu where the contact name appears, including sending SMS, MMS, modifying information, etc. Click Send SMS to enter the Send SMS page! Enter the message content in the input box, and click Send to prompt that the message was sent successfully!
