Qualify eSIM profiles before they become customer-impacting failures.
Profile issues discovered in production can trigger failed downloads, customer-care calls and urgent supplier escalation. Profile Sentinel helps teams detect risks before launch.
AI-powered eSIM profile qualification platform

The business risk
Production incidents start before production.
When an eSIM profile configuration issue reaches production, customers may fail to download or activate their profile. Operators must escalate to the supplier, isolate the issue, request a correction, retest and redeploy — a full delivery cycle at the worst possible moment.
Without pre-production qualification
Faulty profile
Failed activation
Customer-care pressure
Supplier escalation
Emergency correction
With Profile Sentinel + Clause
Pre-production qualification

Correction before launch
Confident go / no-go
Why it is hard today
SAIP profile review is expert work — and expert time is scarce.
Complex ASN.1 files
SAIP profiles are dense ASN.1 structures that are difficult to read and interpret by hand.
Standards fragmentation
The answer is spread across GSMA, TCA, ETSI, 3GPP, ISO/IEC, GlobalPlatform and JavaCard specifications.
Multi-release ambiguity
Behaviour shifts between releases; the right clause depends on the version in play.
Manual expert bottleneck
A complete review is slow and often not feasible under project pressure.
Static reports are not interactive
A PDF helps, but it is not a workflow you can interrogate or drill into.
Supplier assurance is not enough
Operators often rely on supplier sign-off, with little independent evidence of their own.
The product
One workbench, six powers.
Profile Sentinel is not one tool bolted to another. It is a single, authenticated workbench where a team can design, decode, check, compare, learn and ask — every step grounded in the standards.
Design
Author and generate a valid SAIP profile — from a template, from scratch or from import — and prove it round-trips byte-for-byte.
Decode
Reconstruct the full file system and interpret every element — access conditions, security domains, applications and OTA.
Check
Run 200+ standards-informed rules; each finding is severity-classified and traced to its clause.
Compare
Put two profiles side by side — golden vs candidate, release N vs N+1 — and see what changed.
Learn
Reach a curated standards knowledge base — 1031 fiches, EF-linked and release-aware.
Ask
Ask Clause, the assistant that cites its sources, right where you are working.
The platform
Six pillars. One place to design, decode, check, compare, learn and ask.
No existing tool offers the combination. Three of these have effectively never been done together: generate a byte-round-tripping profile, compare two profiles element by element, and a grounded assistant that cites its sources.
Profile Design Studio
DesignAuthor a SAIP profile — and prove it round-trips. Not just read a profile: generate one.
- Design → edit → validate → generate → export, from a template, from scratch or from import
- Strict round-trip oracle — byte-identical output, and it fails on a wrong Ki
- Generates Milenage / TUAK test vectors and a DER export package
In every tier
Profile Cockpit
DecodeDrop a SAIP file; in seconds the whole file system is reconstructed and every finding is pinned to the exact element it affects.
- Deterministic ASN.1 parse + 5-layer MF / DF / ADF / EF reconstruction
- 12-tab element explorer — access conditions, security domains, keysets, OTA, applications
- Findings attached to the exact EF, app or access condition — symptom to evidence
In every tier
Profile Compliance
Check200+ standards-informed rules run automatically, severity-classified, each traceable to a clause — honest about what it cannot assess.
- Rule Catalogue 1.0 → severity-classified diagnostic findings, not a pass / fail verdict
- Rules traced to standard and clause; derived rule-to-standard coverage across 16 standards
- Per-rule detail and a rule simulator that re-runs analysis on a generated profile
In every tier
Profile Delta
CompareTwo profiles, side by side. Golden reference vs candidate, release N vs N+1 — what changed, and does it matter.
- First-class two-profile comparison, aligned with the Cockpit deep-dive UX
- Candidate picker → element-by-element comparison with value-true compare
- Clause bound to the comparison context for a sourced explanation of a change
In every tier
Knowledge Base
Learn1031 curated standards fiches, EF-linked and release-aware — guidance on top of the source, not a raw spec dump.
- Curated across GSMA, ETSI, 3GPP, TCA, ISO/IEC, GlobalPlatform and JavaCard
- EF-to-fiche index; each fiche lists the precise EFs it defines and the clause
- Tolerant search, tiles and “Ask Clause” from any fiche

Clause
AskAsk in plain language, get a sourced, release-aware answer — right where you are working, not a generic chat window.

EF content & interpreted values
Decoded elementary-file content, interpreted for review.
Access conditions
Read / update / activate conditions per file.
PIN / PUK / ADM
Secret-code settings where available and authorised (by reference; key material never exposed).
Security domains
ISD · SSD · CASD configuration and roles.
Keysets & privileges
Keyset references and privilege bits, by reference.
OTA / RFM / RAM
Applications, TARs, keysets, security levels.
Installed applications
AID, priority, minimum security level, package / instance, parameters.
Rule findings & gaps
Detected gaps, warnings, doubts, non-assessable areas, recommended checks.
Word Report 2.0
A structured technical report for supplier and stakeholder communication.
Backed by Rule Catalogue 1.0 — 200+ standards-anchored rules and diagnostic signals.
live The differentiator
Clause
Standards. Sourced. Explained.
Clause
Standards. Sourced. Explained.
The standards-aware AI assistant for telecom engineers.
Clause turns the telecom standards corpus into a conversation. Instead of spending hours searching for the right clause across GSMA, TCA, ETSI, 3GPP, ISO/IEC, GlobalPlatform and JavaCard specifications, engineers can ask Clause and get a sourced, release-aware answer directly in the qualification workflow. And because Clause is embedded in the Profile Cockpit, you can ask about any EF, finding or rule in context — not a generic chat window.
Sourced answers
Traceable citations and source references — retrieve, don't invent.
Release-aware
Citations reflect the version that applies, where available.
Anti-hallucination
A strict citation contract: no unsupported normative claims.
“What is EF UST?”
“What is the purpose of SELECT?”
“Explain this EF.”
“Why did this rule trigger?”
“What should I review next?”
Clause
What is EF UST?
EF UST (USIM Service Table) is a mandatory file in the USIM application that indicates which optional USIM services are available and activated — a capability bitmap the ME reads at startup.
Standards references
3GPP TS 31.102 §5.1.7
ETSI TS 102 221
Suggested checks
- Confirm service bits against the intended provisioning
- Cross-check structure vs the dictionary expectation
Bit positions & service definitions?
Access conditions of EF UST?
