TELECOMMUNICATIONS CARRIERS
SIM swaps and account changes the subscriber actually asked for
A phone number is the recovery key for most of the internet, which makes SIM swaps and port-outs a prize. Carriers also hold trusted relationships with billions of devices, making them natural operators of UniKey verification for everyone else.
THE PROBLEM TODAY
Credentials stand in for permission
SIM swap
A store or call-centre agent moves a number to a new SIM on the strength of personal details anyone can buy.
Port-out fraud
Numbers are ported to another carrier, taking every SMS one-time code with them.
SMS as authority
Banks and apps treat a code sent by text as proof of authorization. It is proof of possession, at best.
WITH UNIKEY
Actions that carry a Trust Packet
Each one is signed by the party with the authority to take it, and verified before it executes.
-
Swap a SIM
A SIM change needs a Trust Packet from the subscriber's existing device, not just their details.
-
Port a number
Port-out requests carry the subscriber's signed authorization, verified by the losing carrier.
-
Change the account owner
Ownership and plan changes are signed by the account holder and recorded.
-
Verify for others
The carrier operates a verification endpoint, confirming packets for banks and apps.

Illustrative. The verifier looks up the signer's public key in DNS, checks the Ed25519 signature, refuses a packet it has seen before or one past its expiry, and only then lets the action run.
