Official references. Independently written explanations.
Editorial method
The provider context was checked against accessible official pages on 20 September 2026. Long-form explanations are general practical guidance. A reference link is not a claim that all possible products, legacy terms or device combinations have been verified.
How uncertainties are handled
Where a product feature was not verified, the guide asks the reader to confirm it. Historical background is limited to supported statements. Product availability is not inferred merely because a parent business or host network offers something similar.
Updating a guide
A provider can change its current offer without changing all older agreements. Corrections should identify the affected statement and the applicable product or date. The contact page explains how to raise a content question without sending private account details.
Coverage of the edition
Three, O2, EE, Vodafone, Sky Mobile, Tesco Mobile, giffgaff, SMARTY, iD Mobile and VOXI are included. This is a selected UK directory, not a claim to include every network. Prices are intentionally not reproduced; readers should use an official quote and contract summary.
