Can’t send an SMS? Please check the following points:
1. When using Dingtone to send an international SMS, remember to add the country code before the mobile number. For example, add “+91” before Indian numbers.
2. 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.
3. Due to regulatory reasons, you must have a Dingtone phone number to send SMS to recipients in U.S. and Canada.
