Our position. teesrition is an independent information service for mobile customers in the United Kingdom. We are not a mobile network. We have no affiliation with, endorsement from, appointment by or connection to Three, EE, O2, Vodafone, Sky Mobile, Tesco Mobile or any other provider, and no commercial arrangement with any of them. We do not sell, supply, arrange or broker SIM cards, contracts, handsets or services of any kind, and we take no commission from anybody. Everything here is general information; a provider's own current terms always take precedence.
01

What the app is for

Purpose

Far more than looking at a bill. Every network's app carries live usage figures, spend caps, add-ons, roaming settings, eSIM requests and a written support channel.

Written support leaves a transcript with a reference number, and a telephone call leaves nothing.

Do this
  • Install it on day one and set the free spend cap.
  • Use the written route for anything you may need to prove.
02

What each network's app covers

Coverage
NetworkWhat its app covers
ThreeOne app: allowances, billing, caps, add-ons, roaming, eSIM
EEAmong the fullest — family SIMs, device unlocking, broadband controls
O2Two apps sharing one login — the account and a separate rewards platform
VodafoneOne app covering allowances, billing, caps, roaming, eSIM
Sky MobileOne login covering television, broadband and mobile together
Smaller brandsLighter apps or web dashboards; one has no telephone route at all
Do this
  • Check what support routes exist before you buy, if that matters to you.
03

Why the login matters

Security

Your mobile account controls the phone number your bank sends authentication codes to. On some networks the same login now opens broadband and television as well.

WarningIf your phone loses service for no reason and does not come back, that can mean your number has been moved to somebody else's device. Ring the network's fraud line straight away, from a different telephone.
Do this
  • Give the account a password used nowhere else.
  • Switch on every additional protection offered.
  • Read one-time codes to nobody.
04

The five-second test

Cold calls

Genuine offers exist inside the network's own app. Caller ID is trivially faked and personal details circulate freely after data breaches, so a caller knowing your name and plan proves nothing.

Do this
  • Open the app and look before responding to anything.
  • Never agree to anything on a call you did not initiate.
  • Forward scam texts to 7726, free of charge.
