Does PlugMate use a SIM card? How does it ensure call security? It uses end-to-end encryption by default. Does this mean that no third party can know the content of the call?
PlugMate does not support a physical SIM card, so there is no risk of call interception. All communication goes through the host device’s network connection. If you need higher-security private communication, we recommend installing a dedicated encrypted messaging app.
