Over‑the‑Air SIM Management at Carrier Scale
Secure 3GPP TS 23.048 OTA (SCP80/81) for SIM applet updates, PLMN/APN file changes, and campaign orchestration across 2G/3G/4G/5G SA and LPWAN fleets.
GSMA/3GPP‑aligned • Tier‑1 SMSC/SMPP • Real‑time KPIs & rollbacks • Multi‑tenant & audit‑ready
Trusted by operators and OEMs in EMEA

The problem we solve
Updating SIM parameters and applets across heterogeneous fleets is risky and slow. Key rotation, rate‑limits, and vendor fragmentation add operational overhead.
Our solution
- Campaign Orchestrator – Segment by IMSI/ICCID, PLMN, device model; stage, canary, and roll back in one click.
- Secure OTA – SCP80/81 key management, counters, TAR whitelists; throttling and retry logic.
- Observability – Live DLRs, success/error codes, and per‑TAR analytics with exportable reports.
Platform overview
Campaign Orchestrator
Target by IMSI/ICCID, PLMN, MSISDN ranges, IMEI TAC, geography. Canary groups, rate limits, windows, and safety stops.
SIM File Manager
Manage EF updates (PLMN/OPL, APN, STK, BIP). Upload APDU payloads, validate TAR mapping, and simulate before send.
Security & Keys
SCP80/81 key sets, CNTR handling, per‑issuer policies, dual‑control workflows, HSM integration.
Messaging
SMPP/SMS‑C integration, concatenation, DCS/UDH handling, MT/MO tracking, delivery receipts. Optional SS7/Sigtran.
Integrations
REST APIs & webhooks; import from CRM/BSS; export to data lake. Hooks for NEF/5G events, HLR/HSS/UDM reads (where available).
Governance
Multi‑tenant, RBAC, SSO, audit trails, immutable logs. Data residency options (EU/CH).
Use cases
- Roaming & steering – Update PLMN priority lists and steering policies by segment.
- IoT fleet ops – Roll out APN/STK/BIP changes to devices with limited windows or power budgets.
- Applet lifecycle – Install/enable/disable SIM applets; trigger events; manage TARs.
- Emergency response – Fast, safe bulk fixes with canary + rollback.
How it works
- Connect – Link SMSC/SMPP and optional HSM; set keysets and issuer policies.
- Target – Import segments (CSV/API) and select EF/APDU updates. Simulate and schedule.
- Observe – Monitor success/error codes in real time; auto‑retry/rollback by rule.
Compliance & security
- 3GPP TS 23.048 OTA; SCP80/81 key management
- Operational controls: dual approval, maker‑checker, signed releases
- Least‑privilege RBAC, SSO/SAML/OIDC
- Encryption in transit/at rest; optional HSM for keys
- Change history & exportable audit logs
Metrics & reporting
- KPIs: Delivered, Applied, Error by reason, DLR latencies, retries, throttled events, affected IMSIs/ICCIDs, top TARs.
- Exports: CSV/Parquet; webhook to SIEM/BI tools.
For developers
- APIs: REST + webhook callbacks (job events, DLRs, error codes).
- SDKs: cURL examples; Postman collection.
- Docs: Getting started, payload guidelines, error dictionary, rate limits.
