Phone plans

Three ways to get a handset, the single calculation that settles any offer, and the month in which most households quietly begin overpaying.

How we are placed. thurlowvance 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.
Note 01

The three routes

RouteWhat it meansWho uses it
Combined bundleHandset and airtime as one monthly figure; does not fall at term endMost networks
Split contractDevice credit ends at repayment; airtime billed separatelyO2, Sky Mobile
Outright plus a SIMNo credit agreement at all; money needed upfrontAnyone

Whichever you choose, the outright route is the benchmark to measure the others against — even if you do not take it.

Note 02

The calculation

Cost slides between the upfront payment and the monthly figure like a see-saw. That is exactly why two shops can show completely different structures for the same handset and both call theirs the cheapest.

  1. Add the upfront payment to the monthly charge multiplied by the number of months.
  2. Work out the same phone bought outright plus the cheapest SIM that suits you, over the same period.
  3. Take whichever total is smaller.
  4. Value any bundled earbuds or watch at what you could genuinely resell them for.
Note 03

The month people begin overpaying

Nothing happens automatically when a minimum term ends. On a combined bundle you carry on paying for a handset you already own, indefinitely. On a split contract the device payment does stop — but the airtime continues at full price until you reduce it.

Within days of that date, do one of three things: move to SIM-only and keep the phone, upgrade deliberately after doing the calculation, or leave.

Worth knowingDiary the end date on the day you sign, with a reminder a month before. That single calendar entry is worth more than any comparison website.
Note 04

Trade-in, delivery and returns

MatterWhat to know
Trade-in valueSwings with condition, storage size and season — take the maker's quote and one independent one
Before despatchErase the handset, unlink every account, photograph it in case of dispute
Delivery promisesBelieve the stock line on the product page rather than the banner
Cooling-offOnline orders carry a period, commonly fourteen days

Use that window properly: test signal at home and at work room by room, test the battery across several ordinary days rather than one charge, and keep the packaging complete until you have decided.
