Warrant Canaries for eSIM Providers: Early Warning System
How warrant canaries work, why they matter for eSIM privacy, and which providers use them.
What Is a Warrant Canary?
A warrant canary is a regularly published statement asserting no secret government orders received. PrivateSims supports transparency mechanisms that keep users informed.
How Warrant Canaries Work
- Regular publication: Dated statement affirming no secret orders
- Removal signals: If an order is served, the canary is removed
- Cryptographic signing: Statements are cryptographically signed
- Specific assertions: May address different types of orders separately
Limitations
Warrant canaries are not foolproof. Legal scholars question enforceability. Users must actively monitor updates. Despite limitations, canaries remain valuable transparency tools. See our transparency reports guide.
