About this product · please read

What EN/ABEL 2.0 is, what it isn't, and what we promise.

What it is

A UK consumer-and-SME mobile service operated by EN/ABEL on top of a UK multi-network carrier relationship (Mobifon Communications Ltd). A SIM-and-service product with a hardened security plane - the Abel stack - sold by discovery consultation only.

What it isn't

Not a government-issued device, not a classified system, and not affiliated with the United States Government, the NSA, the UK Government, GCHQ, NCSC, Apple, Samsung or any handset manufacturer or sitting/former head of state. References to NSA-issued presidential phones, Samsung Knox for US-government use, and FBI/FCDO/GSMA guidance are cited solely to describe the public threat landscape that motivates the product's design.

What we promise

EN/ABEL 2.0 raises the cost and complexity of common attacks against mobile lines. It cannot defeat a state-compelled device handover at a border, an attacker holding the principal's biometrics, or interception methods outside the public domain. "The most secure consumer SIM in the public domain" is qualified by in the public domain - not a claim against classified state systems. Service availability is subject to UK and EU coverage.

Full limits and sources are listed at the bottom of this page - see what we will not say and references.

One product · two front doors

The shift

Until now, this category of line was reserved for principals whose role, profile or family meant a normal SIM was a liability.

EN/ABEL 2.0 opens a limited public intake. Pricing is set by consultation, not published - because the right answer for a listed-company CEO travelling to Asia twice a quarter is not the right answer for a public figure protecting a teenager from stalkerware. Same product. Different deployment. One conversation to scope it correctly.

Presidential-grade threat model

Same threats.
Different audience.
Same answer.

The threat surface that drove the NSA to issue President Obama a custom-modified BlackBerry - now on public display at the National Cryptologic Museum10 - is the same threat surface a board director, founder or public figure faces today on a standard consumer SIM. Samsung publishes a hardened platform (Knox) for US-government use11; the public-domain consumer equivalent of that posture is what EN/ABEL 2.0 delivers.

For the record

EN/ABEL 2.0 is not a government-issued device and is not affiliated with the United States Government, the NSA, or any handset manufacturer. References above are cited to describe the public threat landscape - not to claim a partnership.

Hotel & public Wi-Fi as default-hostile

UK FCDO travel advice for China explicitly tells business travellers to assume hotel and public networks are monitored. The FBI's Denver field office issued the public 'juice-jacking' warning on the same risk class for charging stations and public Wi-Fi.

SS7 / Diameter signalling abuse

The GSMA has documented signalling-layer attack surfaces in FS.11 (SS7) and FS.19 (Diameter) for over a decade. Live exploits against ordinary consumer SIMs were demonstrated publicly at 31C3 in 2014 and have been re-confirmed in academic literature every year since.

SIM-swap fraud at scale

AI-driven voice & number impersonation

Real travel · Real exposure

What happens on a normal SIM. What 2.0 does about it.

Shanghai · 21:40 local · M&A diligence trip

A regional MD lands for a board meeting and joins the hotel Wi-Fi to download the morning's deck. Captive portal, accept terms, done. From the moment the handshake completes, every TLS-stripped fallback, every DNS query, every SIP registration is observable on the local network. The UK FCDO's published advice for travellers to China is to assume exactly this.

EN/ABEL 2.0

On EN/ABEL 2.0 the SIM refuses to fail open. The device prefers the hardware-rooted cellular identity over an unverified Wi-Fi join, routes through a sovereign EU/UK egress by default, and writes a tamper-evident audit row for every routing decision so the trip can be reviewed against your DPIA on return.

Sources: [1]

London → Frankfurt → Riyadh · pre-deal week

A senior counsel travels the deal route carrying privileged communications. On a normal SIM, every roaming partner along the route can attempt SS7 location queries and SMS interception - published, demonstrable attacks against the signalling plane that ordinary consumer SIMs do not defend against.

EN/ABEL 2.0

EN/ABEL 2.0 lines sit behind a signalling firewall posture aligned to GSMA FS.11 and FS.19. Anomalous signalling patterns trigger live key rotation and a notification to the named concierge, not a silent compromise.

FTSE-listed parent · 40-handset C-suite estate

A board considers issuing burner devices for travel. The reality is most executives will use their primary line anyway, and a burner doesn't survive contact with an aggressive welcome pack of public Wi-Fi at the airport.

EN/ABEL 2.0

2.0 covers principals plus optional staff and family lines under the same root of trust - one provisioning ceremony, one named owner, one audit chain - without forcing burner-device theatre that nobody actually follows.

Family office · multi-jurisdictional operations

A principal's vehicle, residence and travel kit each carry connected modules that telemeter location and status. Each of those modules, on a standard M2M SIM, is reachable on the public signalling plane.

EN/ABEL 2.0

2.0 extends the same hardware root of trust to selected M2M lines under the principal's account, with per-line behavioural baselines and a single kill-switch under named authority.

EN/ABEL 2.0 SIM - exploded view of three substrates

Substrate 1

Hardware root of trust · Abel L16

Substrate 2

Sovereign routing logic · Abel L13

Substrate 3

Behavioural baseline · Abel L2

The SIM

The most secure consumer SIM
in the public domain.

Three substrates, one provisioning ceremony, one named owner. The SIM refuses to fail open within the policy boundary defined in your provisioning ceremony: no silent fallback, no helpdesk-overridden re-issue, no opaque routing decision. Every action is signed, hash-chained, and exportable.

How the partnership actually works

Carrier provides the radio.
EN/ABEL provides the security plane.

EN/ABEL 2.0 sits on top of a UK multi-network wholesale relationship spanning the major UK MNOs, per Mobifon Communications Ltd's published service catalogue12. That means your 2.0 line is not locked to a single operator's coverage map and not exposed to a single operator's outage profile.

On top of that radio layer, EN/ABEL contributes the security plane that consumer carriers do not provide to retail subscribers: the hardware root of trust, the signalling firewall posture, the sovereign routing default, and the tamper-evident audit chain. Neither side does the other's job.

We do not claim Mobifon as a sovereign MNO with its own 5G SA core or satellite hybrid; the integration described on the Network page reflects the surface we have built against, not capabilities the carrier has independently published.

Connectivity guarantees · the radio layer

The signal you'd expect from a national operator - across three of them at once.

Security is the headline. Connectivity is the prerequisite. Every guarantee below is either contractual, inherited from a published carrier capability, or governed by an open 3GPP/ETSI specification. We do not invent figures we cannot stand behind.

Best-signal selection

Selected at session start

The modem picks the strongest viable cell when a new attachment is made. Once an IP session is up, handsets do not jump to a stronger network mid-session - that is standard 3GPP/handset behaviour, not a EN/ABEL choice. The Signal Refresh Engine (below) is how we close that gap without breaking the user's session.

Failover behaviour

Automatic re-attach

On loss of the serving cell, the device re-selects the next available network per published 3GPP procedures. No manual intervention from the principal.

Sovereign egress posture

UK + EU preferred

Routine sessions prefer a UK or EU egress point by default. Visited-network breakout is used only where local lawful-intercept rules require it, and that decision is written to your audit chain.

Network hopping · plain English

The line is not married to one mast.

The 2.0 SIM is provisioned across the underlying multi-MNO wholesale relationship, not a single operator. When you place a call or open a session, the device evaluates the available networks and attaches to the strongest viable cell. If that cell degrades - you walk into a basement, a mast goes down, you cross a coverage seam - the modem re-selects another network per the published 3GPP procedures.

For the record: this is standard cellular behaviour enabled by the multi-MNO SIM. It is not a proprietary EN/ABEL radio technology, and we do not market it as one. The EN/ABEL contribution sits above this layer - in the security plane, the sovereign routing default, and the audit chain.

Signal Refresh Engine · DDRR

Detect → Defer → Refresh → Reroute → Reconnect.

Once a phone is attached to a cell with an active IP session, it does not roam to a stronger network on its own. The EN/ABEL app closes that gap with a four-step engine that is fully compliant with App Store and Play Store rules - never silent, never disruptive.

1 · Detect

Real connection quality

RSRP/RSRQ where exposed by the OS, plus latency, jitter, packet loss, throughput, failed retries, and cell-change-vs-performance deltas - not just bars.

2 · Defer

Never interrupt the user

If you're on a call, streaming, navigating, typing or in an email, the engine waits. Zero disruption is the rule.

3 · Refresh

Single-tap, user-approved

When you're idle, a subtle prompt offers a one-tap refresh. We never silently toggle airplane mode - Apple and Google do not allow consumer apps to do that.

4 · Reconnect

Multi-MNO re-attach

The refresh drops the stale attachment, the multi-MNO SIM re-scans, and the device attaches to the strongest viable cell per 3GPP TS 23.122.

Enterprise extension

On MDM-managed and Android Enterprise device-owner handsets, parts of the refresh cycle can be automated, APN and routing policy controlled, and a private APN enforced - without losing the audit trail.

DDRR technical explainer (restricted)

What we will not promise

Coverage and signal strength are inherited from the underlying UK mobile network operators and are subject to their published coverage maps. EN/ABEL does not own radio infrastructure and does not guarantee service inside radio dead-zones, in tunnels, below ground, or in jurisdictions outside the carrier compatibility list. We do not publish an end-to-end uptime SLA for components we do not own end to end. We do not silently toggle airplane mode or force a cellular reset on consumer iOS or Android - the Refresh step is always user-approved.

Not the ordinary UK telco market - that comparison lives on /transparent-comparison. This table shows the products that actually compete with 2.0 in the secure / sovereign mobile category, with publicly verifiable pricing and capability data.

Any device · no modified hardware

Keep your iPhone.
Keep your Galaxy.
Get the protection.

EN/ABEL 2.0 delivers its security at the SIM and network layer - not the handset. It does not require a modified, custom-built or jailbroken phone. Any current-generation iPhone or Android that accepts a standard SIM (or eSIM) can run a 2.0 line, and the same protections apply identically across both ecosystems.

The SIM is the security boundary

A SIM is an independently certified secure element with its own cryptographic processor. The handset doesn't need to be modified for the SIM to enforce policy.

The network plane does the rest

Defences against SS7 / Diameter abuse, SIM-swap and silent re-routing live in the carrier core, above the handset. This is where Abel sits.

Source: GSMA FS.11 (SS7) · FS.19 (Diameter)

Why others built custom phones

Bittium, Blackphone, KryptAll and Librem 5 ship modified hardware as a deliberate architectural choice - their security plane is integrated with the device OS. We chose the opposite architecture.

Source: Each vendor's own product page

What this claim does and does not cover

"Same protections" refers to the SIM-and-network plane only. Device-level threats - a compromised OS, a malicious app installed by the user, biometric coercion, a state-compelled handover at a border - are outside that plane and are addressed by the threat-profile workshop, not by the SIM. Device support is subject to the carrier's standard handset compatibility list (4G/5G bands, eSIM where used). We do not claim universal compatibility with every device ever made.

What others charge

A range, not a price.

Public secure-mobile plans range from $99/mo (Efani) to government-grade hardware lines from €1,795+ one-off (Bittium) plus service. Custom-modified iPhones from $4,500 (KryptAll). Several enterprise-grade vendors don't publish at all.

Figures sourced from each vendor's public pricing page - see Sources beneath the matrix.

Why we don't publish a number

Same product. Different deployment.

The right answer for a listed-company CEO travelling to Asia twice a quarter is not the right answer for a founder protecting a single executive assistant. Same SIM. Same Abel stack. Different threat surface - different scope. One conversation to size it correctly.

What's in the box

Concrete, verifiable, mapped to our own security stack.

Hardware root of trust on the SIM

Per-line cryptographic identity issued in a provisioning ceremony, not a high-street activation.

Abel L16 · Cryptographic provisioning

Live key rotation under attack signal

Sub-minute rotation when the signalling firewall flags a credible anomaly against the line.

Abel L17 · Live key rotation

Sovereign EU/UK routing by default

No best-effort, no paid upgrade. Every session prefers a sovereign-resident path with a signed routing decision.

Abel L13 · Sovereignty routing (twin-disclosed)

SS7 / Diameter signalling firewall posture

Edge inspection aligned to GSMA FS.11 and FS.19 - the published industry baseline most consumer SIMs do not implement.

Abel L3 · Signalling anomaly detection

Cryptographic SIM-swap defence

Re-issue requires proof tied to the provisioning ceremony. A high-street store cannot port your line.

Abel L22 · Money-path / identity guard

Per-line behavioural baseline

Each line has a rolling expected-behaviour profile. Deviations page the concierge, not next quarter's review.

Abel L2 · Per-SIM baseline

Tamper-evident audit chain, customer-exportable

Hash-chained evidence of every routing decision, signalling event and policy invocation - exportable on demand for your security or legal team.

Abel L23/L26 · Evidence chain

24/7 named human concierge

Not a script, not a queue. One person, named, with the authority to act on your behalf inside the platform.

Optional family / staff lines under one root

Provision additional lines for partner, children, EA or principal investment manager under a single root of trust.

Annual independent threat review

Delivered to the principal in private, covering threat surface specific to their role, family and travel pattern.

Eligibility & how it works

Three steps. No public price. One named owner from day one.

01

Discovery call

30 minutes. NDA on request. We listen first; we scope the threat surface honestly; we tell you whether 2.0 is the right answer or whether one of our existing tiers fits better.

02

Threat-profile workshop

EN/ABEL team plus your security lead, EA, or principal advisor. We map travel patterns, family structure, public exposure, and produce a written threat profile signed by both sides.

03

Provisioning ceremony

Issuance of the hardware-rooted line(s), introduction of the named concierge, baseline of the audit chain. From this point your line cannot be re-issued without cryptographic proof.

Advocate Programme · uncapped

Bring someone in. Be rewarded - every time, every line, no ceiling.

The most practical and useful mobile and communications network of the day deserves advocates who can speak to it from the inside. That's the model - uncapped, transparent ledger, paid against the wallet you can see at any time.

How it works

One conversation. One reward chain.

Bring someone into a EN/ABEL 2.0 discovery call. If they onboard, you're rewarded - and so is everyone they then bring in, within the limits set out in the Advocate Terms. The chain is structured, attributed, and visible.

The model

Uncapped per-line credit. Tiered multiplier.

Per-line credit on every successful onboarding. A tiered multiplier scales the credit for advocates with sustained successful referrals. Everything is paid against your wallet ledger - you can see it move in real time.

Specific rate card and tier thresholds: see Advocate Programme Terms.

Why it scales for active advocates

The chain attributes upward.

As each successful referral becomes an active customer, their own onward referrals attribute a structured share back to the originating advocate, within the limits of the Programme Terms. Active advocates compound.

Read the Advocate Terms

The Advocate Programme is governed by the Advocate Programme Terms and operated under the existing wallet ledger and referral payout infrastructure. Rate card subject to publication and review. No guarantee of any specific earnings is made or implied. Referral attribution is auditable end-to-end via the hash-chained audit log.

What we will not say

The honest limits - included on purpose.

  • EN/ABEL 2.0 is not a government-issued device and is not affiliated with the United States Government, the National Security Agency, or any other state security service.
  • EN/ABEL 2.0 has no formal partnership with Apple, Samsung, or any other handset manufacturer. Public references to manufacturer-provided security features (e.g. Samsung Knox) are cited to describe the public threat landscape only.
  • We cannot prevent a customer from being lawfully compelled by a state to hand over a device or unlock it at a border crossing.
  • We cannot defeat an attacker who has come into possession of the principal's actual unlock biometrics or PIN.
  • We cannot guarantee defeat of zero-day baseband or modem-firmware exploits that have not yet been disclosed by the affected vendor.
  • We cannot guarantee against insider threat at the underlying mobile network operator. The Abel audit chain is designed to detect and evidence such activity, not to prevent it physically.
  • The phrase 'the most secure consumer SIM in the public domain' is qualified by 'in the public domain' - we make no claim against classified state systems. It is substantiated by the comparison matrix on this page against publicly published competitor data as of April 2026 and is subject to ongoing review.
