Allow/Deny List

Control exactly who can send and receive SMS through your device

Anyone can text your SMSEagle unless you say otherwise. Allow/Deny List puts you in control of exactly who gets through, in either direction.

One mode at a time, device-wide

Only Allow or Deny is active for the whole device at once, so there’s never a conflict between overlapping rules.

Filter incoming and outgoing traffic the same way

The same list controls who can text in and who SMSEagle can text out, so your rules stay consistent in both directions.

Number ranges, not just single numbers

Add the start of a number with an asterisk, like +4420*, and the list covers every number with that prefix, such as a whole country.

Allow/Deny List: FAQ
