If you fail to send an SMS, you’re suggested to check the following items:
- Please check your contact’s phone number to make sure it is a complete phone number consisting of country code, area code and a number. If any of the three parts is missing, you’ll fail to send a message.
- Please make sure the contact’s phone number is correct and valid. It’s convenient to select a number directly from your contact list. If you can’t access your contacts, you can go to your phone’s “Settings” >> “Privacy” >> “Contacts” and check that you have enabled Dingtone to access your contacts. This is to make sending an SMS more convenient and Dingtone will not invade on your privacy.
- Due to regulatory reasons, you must have a Dingtone phone number to send SMS to recipients in U.S. and Canada. You can check your Dingtone phone number by tapping “Connect” >> “My Phone Numbers”.
