We checked the official pages below when preparing this edition on 18 September 2026. Network pages identify their source. Our practical checklists are original general guidance; they are not copied provider instructions or a promise of product availability.
How to read the guides
Each topic begins with a provider-specific note, followed by general explanations and questions. A shared radio network does not establish identical benefits, apps, speed policies or roaming. Where a feature is not verified, we ask you to confirm it rather than claim it exists.
Scope and corrections
The library covers ten selected mobile brands. It is not a live tariff database, a complete record of every historical product or a ranking of providers. We avoid quoting prices because an account-specific quote and contract summary are more reliable for a decision. Contact us if a source has changed.
