A useful distinction
The network carries the signal.
Your agreement defines the service.
Shared coverage does not automatically mean shared roaming, apps, support or account terms. Ask about the exact product you intend to use.

Follow the question.
Practical articles for choosing, using and changing a mobile service.
Decisions
Before you choose a mobile service
Begin with a short description of your own routine. A useful comparison follows your requirements, not the order of a provider’s advert.
SIM-only, prepaid and phone packages
These names describe different parts of a service. Understand what each adds before comparing them.
Monthly bills and the year ahead
Think in billing periods and components. A payment total alone rarely explains a change.
Phone ownership, returns and upgrades
The moment a phone arrives, the moment it is paid for and the moment you can upgrade may be different.
The boundaries of unlimited
A data-quantity label is not a promise about every speed, device, application or country.
Looking beyond the featured networks
The UK has more retail mobile brands than this publication can comprehensively catalogue. Use the same disciplined checks when investigating another service.
Everyday use
Coverage in the places you use
Reception is local. A national percentage or a friend’s experience cannot describe every room and journey in your life.
A careful eSIM changeover
Plan for recovery before installation. Your mobile line is often part of the way you access other accounts.
Travel checks before you leave
Roaming, international calling and a travel eSIM solve different needs. Match the rule to the activity.
Home broadband and mobile backup
Assess the fixed connection, home Wi-Fi and mobile backup as separate parts of the household setup.
Keeping household lines manageable
Separate the user of each phone from the person responsible for its agreement.
Changing service
Moving a number with PAC or STAC
A transfer should preserve the number you want while making the remaining obligations clear.
Work through a connection fault
Record the symptom before changing settings. The aim is to isolate the failing part while preserving what still works.
A clear complaint record
A complaint works best when the requested correction and supporting evidence are easy to identify.
Recognising unsafe support approaches
Knowing the name of a network or a recent corporate change does not prove that an unexpected caller represents it.
