Why can't I find the contact in my mobile phone by sending a text message with my mobile phone software 139?

What software does Pro use? At present, the mobile phone client using 139 mailbox does not support SMS function. If the mailbox logged in with "139 Email Lightweight Edition" supports SMS, and you can find the contacts in the email address book instead of the contacts in the mobile phone address book, enter the SMS page, click the symbol on the right side of the "mobile phone" column, and add the contacts in the email address book, as shown in the following figure. If you want to add phone address book contacts to your mailbox, you can set up an exchange synchronous phone address book. Please refer to/staticmhtml/0/content/1664.html for the operation method. I hope I can help you!
