What Happens When Your Mobile Contract Ends?

Your phone usually keeps working when your mobile contract's minimum term ends. Your number stays with you, and the service normally continues until you change plan, switch provider or cancel. You do not have to renew or buy a new handset. What needs your attention is the price you pay next and whether you still owe money for the phone itself.

Quick answers

• Does service stop? Normally not. The minimum term ends, and the service usually continues.
• Does my bill fall? Not necessarily. Ask for the next monthly price in writing.
• Do I still owe for the phone? Possibly. Handset finance can run past the airtime term.
• Can I keep my number? Yes. Text PAC to 65075 to get a code.
• Is there an exit charge? Normally no airtime early-termination charge once the minimum term ends; separate handset debt may remain.

The more useful question is not simply “Is my contract over?” It is “What will this phone and the service I actually need cost over the next year?”

What happens on the day your mobile contract ends?

The end date is normally the end of your minimum commitment and not the end of your mobile service. In most UK pay-monthly agreements:

• Your number stays active. Calls, texts and data normally continue under the provider's post-minimum-term arrangements.
• Your plan does not move to the cheapest tariff. You may stay on your current rate, move to another rate or receive a discount under your provider's terms.
• You can usually consider other providers with no airtime exit charge. Check cancellation terms, your final bill and any separate agreements first.
• You do not need a new handset. An older phone works well with a new SIM if it is compatible and has a suitable signal.

If you do nothing, your service normally carries on at the applicable post-contract rate. Ending the minimum term does not itself force you to buy a new phone or accept another fixed-term deal. Out of contract does not mean out of service — or on the best deal.

Cancelling is different from switching. If you ask to disconnect your service rather than switch, your provider may still require a contractual notice period after the minimum term; check the period stated in your agreement or end-of-contract notice. If you switch using a PAC or STAC, Ofcom says your old provider cannot charge for a notice period after the switching date. That does not wipe out an existing bill or separate handset finance.

How do you know when your mobile contract ends?

Text INFO to 85075 from the number you want to check. You can also look in your provider's app, online account or contract documents. If a minimum term is still running, ask about any early termination charge before you decide.

Under Ofcom's end-of-contract rules, your provider must notify you between 10 and 40 days before the minimum term ends. The notice must include the end date, any notice period, your current and post-contract prices, information about bundled agreements and the provider's best available deals, including relevant new-customer prices. Providers must also send annual reminders to customers who are already out of contract.

Read the notice for its facts and use the quoted renewal offer as a starting point for comparison. It is not proof that you have the cheapest suitable option.

Will your mobile bill go down when the contract ends?

Not necessarily. It depends on whether the airtime and handset were sold together or financed separately, and on what your agreement says happens after the minimum term.

The contract end date and the date the phone is paid off can differ. With separate handset finance, a PAC does not cancel or pay off the device loan. Ofcom's guide to choosing a mobile package advises checking the phone payment agreement separately, especially when it runs longer than the airtime commitment.

Do not assume every customer on an old combined contract still pays the full original charge. Some providers reduce charges automatically; others may not. Check your next bill or a written post-contract quote before calculating a saving.

How much could switching to SIM-only save?

Hypothetical example: your old handset is fully paid off and continuing the service would cost £25 per calendar month. A comparable SIM-only plan at £8 per calendar month changes the sums as follows, assuming twelve unchanged payments and no switching charges or paid extras:

That is £17 a month. The comparison holds only if the £8 plan has enough data, reliable coverage and the calling or roaming features you use. If its £8 rate is introductory and later rises, calculate each period separately and do not multiply the first payment by twelve.

If the handset loan is still running, separate the two bills. Suppose your current £40 payment is £25 airtime plus £15 handset finance. If your agreement lets you move the airtime to an £8 plan and keep paying the £15 instalment, your total is £23 and not £8. You save £17 on airtime and still owe the phone payments. Switching rights and the treatment of the finance balance depend on your actual agreements.

A plan billed every 30 days is not necessarily billed once per calendar month: twelve 30-day periods cover only 360 days. Check renewal dates and distinguish payments made from the value of service extending beyond your comparison period. If contract length is part of your decision, see our 30-day versus 12-month unlimited SIM comparison.

Stay, renegotiate, switch SIM or get another phone?

No option wins automatically. Staying is a valid decision if your provider offers a competitive total cost and the service suits you. You should be able to say why it beats the alternatives.

Ask your current provider for a better price first

You do not need to threaten to cancel. Tell the provider your monthly bill, your actual data use and the price of a comparable alternative. Ask: “What is your best price if I keep my phone, how long does it last, and what will I pay afterwards?” Request the full offer and any new minimum commitment in writing.

A fair retention offer can be the easiest fix. Compare it on total cost, minimum commitment, roaming and extras, not just the first bill. If a discount lasts only three or six months, include the later rate in your calculation. Under Ofcom’s price-rise rules, new consumer contracts taken out from 17 January 2025 cannot use inflation-linked or percentage-based price-rise terms: specified rises must be stated upfront in pounds and pence, with their timing. Older agreements may still contain different rise clauses. A new fixed term is not necessarily a fixed-price promise.

How to keep your phone and pay only for the service you need

Start with your last two or three ordinary months of mobile data use in your provider account. Pay particular attention to your busiest typical month, and note whether an unusual holiday or one-off download is likely to recur. If you are unsure how much data you need, use our UK mobile data allowance guide before paying for a larger plan. Then check the signal where you live, work and travel. Ofcom's mobile package guidance recommends comparing local coverage and the complete cost, including extras.

Then choose the route that fits your main goal:

• Cut the bill: compare SIM-only deals under £10 and check the full price schedule on any offer you shortlist.
• Avoid a new long commitment: use our 30-day and no-contract SIM comparison.
• Keep EE-based coverage: browse EE-network SIM deals, including selected offers from 1pMobile and Lyca Mobile. The same underlying network does not guarantee identical speeds, features or support.
• Try a Vodafone-based alternative: check Lebara SIM-only offers if Vodafone coverage suits you, and verify the international-calling and roaming benefits instead of assuming they are standard.
• Use a lot of data: compare unlimited SIM-only deals, but only if your usage justifies the cost.

If you are unsure which fits, the full UK SIM-only comparison lets you compare selected offers by data, network and contract. Open Full plan details on a suitable tariff, then use its existing View Deal link to reach the provider and confirm the final terms. A smaller operator can be better value, but do not pick it just because it shares a host network.

Can you keep your mobile number when the old contract ends?

Yes. An ordinary provider switch does not require you to give up your UK mobile number. Ofcom's Text-to-Switch rules give you three codes:

• PAC to 65075: get a code to keep your number when you change provider.
• STAC to 75075: get a code to switch without keeping the old number.
• INFO to 85075: check your switching and contract status without requesting a code.

A PAC or STAC lasts 30 days. Give the code to your new provider to arrange the change; the switch must normally be completed within one working day. For accounts with more than one mobile number (such as family packages), Ofcom advises requesting your switching code by phone or online rather than the single-number text route. Do not cancel the old service yourself before porting if you want to keep the number. If you have already cancelled, Ofcom says you can still transfer it in most cases within one month of cancellation. Handset finance charges and other lines on the account are separate matters.

Our step-by-step guide to keeping your number when switching covers activation, temporary numbers, eSIM, timing and common mistakes. This article covers the financial decision before you switch.

Five checks before accepting a new mobile contract

1. Check both end dates: the minimum airtime term and any separate handset finance.
2. Get the actual post-contract price: find out whether your bill drops, stays the same or moves to another rate.
3. Work out your real data need: buy headroom you will use and not the biggest number on the advert.
4. Compare the full next-year cost: include promotional changes, known price rises, optional extras and the right billing frequency. For a new longer contract, add up its full minimum-term cost.
5. Check signal and key features: coverage, 5G or Wi-Fi Calling compatibility, eSIM, roaming, international calls and cancellation terms.

A renewal should pass these checks before convenience or a promised upgrade decides the outcome.

Frequently asked questions

Does my phone contract end automatically after 24 months?

The minimum term may end, but your existing mobile service normally continues under its applicable terms until you switch, cancel or agree to another plan. Some handset payment agreements run for a different length. Check the contract itself and not just the date you got the phone.

Will my bill fall automatically when I've paid off my phone?

Not always. With separate finance, the handset instalment should stop when that loan is paid off, but the airtime charge can continue. With a combined agreement, the post-contract bill depends on the provider's policy and your terms. Ask for the next monthly price in writing and do not assume a reduction.

Can I use the same phone with a cheaper SIM?

Usually yes, if the handset is compatible with the new provider's service and SIM or eSIM. Check network coverage and device compatibility first. Ofcom says providers can no longer sell locked phones, although an older handset may still need unlocking.

Am I charged for leaving after the minimum term?

You should not pay an early-termination charge for a minimum airtime term that has already finished. If you cancel without switching, contractual notice and normal charges during that period may still apply; switching with PAC or STAC is different because your old provider must not charge for notice after the switch. Check outstanding bills, add-on terms and separate handset finance.

Can I switch before the contract ends?

You can request a PAC or STAC during your minimum term, but leaving early may trigger charges. Check the amount first and compare it with the saving from switching sooner. An unpaid handset balance may also matter.

Should I upgrade or move to SIM-only?

If your phone still meets your needs, compare SIM-only first. If you do need a new one, compare a handset contract with the total cost of buying the handset separately and adding a SIM at the right price. Neither is always cheaper.

The bottom line

A contract end date is a decision point, not a disconnection date. Check what you will pay over the next year, separate any remaining handset cost, and see whether the coverage and data you actually need could cost less. Then either negotiate a better deal with your provider or compare UK SIM-only plans and use the offer's View Deal link when you are ready.
