eSIM · eUICC
Ship a sensor. Power it on. It joins your fleet.
Beacons owns the eUICC orchestration capability for the L1fe ecosystem. GSMA Remote SIM Provisioning. Hardware-rooted key storage. The internal API that Locks consumes when a Locks customer wants hardware-bound identity.
What eUICC orchestration is
The GSMA Remote SIM Provisioning (RSP) specification defines how programmable SIMs — eUICCs — can be provisioned over the air. A device ships with a blank eUICC. When it powers on and contacts an SM-DP+ server, it downloads a cellular profile and becomes operational on a specific cellular network.
In Beacons Mesh, this is the magic that makes "ship a sensor box anywhere in the world, plug it in, it joins your private mesh" work — without manual SIM swaps or a technician on site.
The internal Locks API
Locks calls Beacons over a private network API (not a library import — see the Locks PRD for the rationale on clean separation). The contract surface:
POST /internal/v1/euicc/profiles GET /internal/v1/euicc/profiles/:eid POST /internal/v1/euicc/profiles/:eid/install DELETE /internal/v1/euicc/profiles/:eid GET /internal/v1/euicc/devices POST /internal/v1/euicc/devices/:eid/bind
This API is not exposed to customers. Customers interact with Locks; Locks internally calls Beacons. The contract is versioned and the two products evolve their releases independently.
Hardware-rooted key storage
When Locks creates a hardware-bound identity, it asks Beacons to bind a Locks-issued did:oas to a specific eUICC. The eUICC's secure element stores the private key and signs operations. The signed operations are verifiable by anyone resolving the DID — and remain verifiable even if every other component is replaced.
Where this is going
Phase 4 work, owned by Beacons.
eUICC orchestration ships in Phase 4 of the Beacons build plan, alongside the cellular provider plugins for Telnyx, Twilio, Soracom, Hologram, 1NCE and Particle. The exit criterion for Phase 4 is that a fleet operator can order 100 SIMs through the Beacons console, ship them, have devices power on in the field, and have those devices auto-join their fleet — without further intervention.
