If you are receiving text message notifications from SubAssistant, but your device isn't making an alert sound when it is received, you'll need to check the settings on your device. 

If you use an iPhone, check the Filter Unknown Senders setting under Messages. Filtering messages from unknown senders turns off iMessage notifications from senders who aren’t in your contacts and sorts the messages into the Unknown Senders tab in the Messages list. Because SubAssistant sends messages from many different phone numbers and the numbers can change at any time, we recommend turning off this option.

  1. Go to Settings  > Messages.
  2. Turn off Filter Unknown Senders.

Note: You canʼt open any links in a message from an unknown sender until you add the sender to your contacts or reply to the message.
