Network apps: who has what
Every network now expects you to run the account from an app. Here's the map — and the one habit that turns any of them into a fraud lie-detector.
Who has which app
| Network | App(s) | Stand-out abilities |
|---|---|---|
| Three | Three app | Diagnostics, eSIM management, roaming controls |
| O2 | MyO2 + Priority (separate) | Device-plan balance; rewards live in Priority |
| Sky Mobile | My Sky (all Sky products) | Roll piggybank, monthly tier changes, household view |
| EE | EE app | Family SIMs, broadband in one account, device unlocking |
| Budget brands | Each brand's own | Depth varies — never the host network's app |
Names and abilities as generally understood at July 2026; the official app-store listings are always current.
Questions
What do all the apps have in common?
Allowances and bills, add-ons and passes, spend caps (set one today), roaming controls, support chat — and increasingly eSIM issue/transfer plus network diagnostics.
I'm on Tesco/giffgaff/SMARTY — can I use the host network's app?
No. Budget brands run their own apps and accounts; the host's app won't recognise you. Every account task lives in your own brand's app.
How does the app expose fraud calls?
In five seconds: any cold caller with an 'exclusive upgrade' — hang up, open the official app, look for the offer. Genuine deals live in the account; the caller's almost never does, because the caller wanted your login, not your loyalty. More: stay safe.
