Can I send short messages to all mobile phone users through the mobile phone 139 mailbox? I sent a message that always failed.

1. Log in to the email address 139, and enter "Mobile phone is not limited"-"SMS writing". 2. In the "Recipient" column, enter the mobile phone number of the SMS recipient, and at most 20 different mobile phone numbers can be entered at the same time, separated by commas. Of course, you can also select recipients directly from the address book. Then fill in the text message. The maximum length can be 58 Chinese characters or 128 English characters (including punctuation). If the length exceeds one short message, the system will automatically divide it and send it as multiple short messages. Finally, click "Send" to finish sending the short message. The fee is 0. 1 yuan/article.
