We are not a network and we sell nothing at all. Each network page opens with a full specification table, then works through fifteen sections covering everything from SIM plans to switching away.

Questions we are asked most

Do you sell anything at all?

No. No SIM cards, no contracts, no handsets, no services. We take no commission and accept no payment for placement. That is precisely why a page here can state plainly that a heavily advertised network has a documented weakness.

Why are there no prices?

Because a stale price is worse than none at all. We explain how pricing works and what to compare, so you can read any current offer properly yourself.

Can you change something on my account?

No. We cannot see, open or alter any account. For anything account-specific, use your network's own official app, website or helpline.

Are you connected to any network?

No. We have no affiliation with, endorsement from or connection to any provider named on this site. Network names appear only to identify the services described.

Would you rather just ask somebody?

Ring us and we will go through it with you. Nothing is offered for sale at any point.

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.

Ring us if these pages do not cover it

We hold no arrangement with any network, take no commission and sell nothing at all. If your question is not answered here, telephone and ask.
