Who runs what
| Three | One app: allowances, bills, caps, add-ons, roaming, eSIM issue, connection checker, chat |
| O2 | Two apps, one login: MyO2 (admin) + Priority (perks) |
| Sky Mobile | My Sky — mobile alongside TV and broadband: reserve, resizes, passes, bills |
| EE | Among the fullest: family SIMs, device unlocking, broadband, caps, eSIM |
| Budget brands | Slimmer apps or web dashboards; giffgaff is entirely online by design |
App safety rules
Official stores only— never install from a link in a text or call.
Guard the login— it protects the number your bank texts; unique, strong password.
Every protection on— whatever extra security the network offers.
The golden rule— genuine offers appear INSIDE the account; that's your fraud detector.
