Primary references
Provider profiles link to official product, support and historical material. Ofcom references support general processes such as switching and coverage interpretation. We explain the material in practical terms rather than reproducing a provider’s promotional claims.
What was checked
Each provider has a current-source supplement reviewed on 15 October 2026. Background sections also draw on research previously gathered on 8 October 2026. This is a dated information edition, not a live feed and not an assertion that every legacy agreement was re-verified.
Facts and advice
History and named features are factual subjects with references. Questions, checklists and preparation steps are editorial guidance. If a service category could not be verified, we say so rather than inventing availability or declaring that it can never exist.
No universal winner
We do not publish numerical tariffs, ranked provider claims or guaranteed savings. The same service can suit different people differently. Device support, local coverage, payment structure and individual circumstances need separate consideration.
Keeping information useful
Before relying on a feature or process, follow the original reference and confirm the current details. To suggest a correction, call 020 3996 2898 with the page title and relevant official evidence. Provider call charges may apply.
Always confirm current details with the official provider. mosaicskiyo is independent and provides general guidance only.
