An honest, sourced and dated side-by-side of UK enterprise operators on the things procurement actually asks about: contract length, mid-contract hikes, sovereignty, security posture and compliance evidence. Boundless is highlighted, but every cell is an objective fact, not a sales line.
Data as of April 2026. Operator names referenced nominatively.
Every figure traces back to a public operator price page or an Ofcom market report. Citations live at the foot of this page.
Snapshot taken in April 2026. We refresh it on a quarterly cadence and timestamp every change.
We compare the same tier of service across operators. Where a competitor doesn't publish a figure, we say so - we don't guess.

What others do
Most UK MNOs are foreign-owned at group level (Telefónica, Vodafone Group, CK Hutchison) and route signalling through global cores.
What we do
Mobifon is a sovereign UK + EU mobile core with all signalling, lawful intercept and data residency under UK + EU jurisdiction.
What others do
SS7 / Diameter signalling firewalling is sold as an add-on on every other network. SIM-level hardware security is not offered.
What we do
Abel is a 26-layer cognitive security system embedded in the SIM and the core - no add-on, no upsell.
What others do
Standard UK telco mid-contract hikes are CPI + 3.9% or RPI - adding 3–5% on top of inflation every year.
What we do
Index-linked, never inflated. One annual adjustment capped at the published UK CPI rate. The index is the absolute ceiling, in writing.
What others do
Most operators provide annual attestation packs on request and rebuild evidence per audit.
What we do
Continuous evidence emitted by the platform itself - NIS2, DORA, GDPR, ISO 27001 - exported on demand.
What others do
Single-network MNOs depend on one radio footprint. MVNOs depend on a single host operator.
What we do
Multi-MNO via Mobifon plus bonded LEO + GEO satellite fallback for sites that need to stay up regardless.
What others do
Mobile, connectivity, voice, security and billing live in separate portals stitched together with PDFs.
What we do
One app and one API for fleet, security, billing and compliance - designed as one product, not three acquisitions.
Comparison data sourced from publicly available operator pricing pages and Ofcom market reports as of April 2026. Operator names are referenced nominatively for honest comparison under the UK Business Protection from Misleading Marketing Regulations 2008. Trademarks belong to their respective owners. We make no claim of affiliation, endorsement, or partnership with any operator named on this page. Where a competitor figure could not be verified from a public source we render "Not published" rather than estimate.
We'll map your current operator's contract, hike clauses and security posture against this table and show you exactly where the gap is - in writing, before you commit to anything.
Tell us a little about your setup. We'll set up a 25-minute walkthrough on the part of transparent comparison that matters to you most - and you'll be talking to someone properly senior, not an SDR.
