The Allow/Deny List feature lets you control both incoming and outgoing SMS traffic on your SMSEagle device. By specifying which phone numbers or number ranges are allowed or blocked, you can ensure that only approved sources can send messages to the device or that outgoing messages are sent only to approved recipients.

Typical use cases

As a result, any further incoming or outgoing SMS communication with that number is blocked according to the Deny selected mode rules.
This feature is especially useful for:
