- bredren 6y agoIt is much more special, because afaik it is the only one that can hook into SMS coming from the carrier. Other messenger apps can be downloaded and installed, but they can only do digital messaging. If you are on Android and you use Signal, but text some random other android user's phone number that uses a pure sms messaging app, is any part of that conversation encrypted?
- damnyou 6y agoIf the other phone is associated with a Signal account at all (regardless of operating system), it will use the Signal transport, otherwise SMS. The Signal UI makes it clear when you're sending unencrypted text messages.
