The three ways to get a phone

The facts

Combined bundle
Phone and airtime as one figure
Split contract
Two separate agreements
Outright plus SIM
No credit agreement at all
Credit check
On any monthly device agreement

What it means for you

RouteWhat it meansWho uses it
Combined bundleOne monthly figure; does not fall at term endMost networks
Split contractDevice credit ends at repayment; airtime billed separatelyO2, Sky Mobile
Outright plus SIMLowest total cost; money needed upfrontAnyone

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

The calculation that settles everything

The facts

Step one
Deposit + (monthly × months)
Step two
Phone outright + cheapest suitable SIM
Step three
Lower total wins
Freebies
Count at resale value only

What it means for you

Cost slides between the deposit and the monthly figure like a see-saw, which is precisely why two shops can show you completely different structures for the same phone and both call theirs the cheapest.

Only the whole-term total tells the truth. Work it out before you discuss anything else, and work out the outright benchmark alongside it.

Watch thisBundled earbuds, watches and speakers should be counted at what you could genuinely resell them for. A deal that only wins because of an accessory you would never have bought has not won.

The month people start overpaying

The facts

Combined bundle at term end
Monthly figure does not fall
Split contract at term end
Device half stops; airtime does not
Notification required
None
Who knows the date
Only whoever wrote it down

What it means for you

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

Within days of that date, do one of three things:

  1. Move to a SIM-only plan and keep the phone you have.
  2. Upgrade deliberately, after doing the calculation on the new offer.
  3. Leave, using the free switching code.
Watch thisDiary 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.

MatterWhat to know
Trade-in valueSwings with condition, storage size and season — get the maker’s quote and one independent one
Before despatchErase the phone, unlink every account, photograph it in case of dispute
Delivery promisesBelieve the stock line on the product page, not the banner
Cooling-offA free trial of the network as well as the phone

Use the returns 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.
