Mobile phone deals

How do pay monthly phone contracts work?

When you find a handset and deal you like, you’ll be sent to the retailer’s website to secure that deal. Here’s what happens next:

Sign up for your new contract - First, check your contract terms. Then, provide personal details for your credit check.

Pay any upfront costs - If you’re getting one of the latest handsets, you might have to pay a fee upfront.

Get your phone - Hooray! Now you can start using your new mobile phone.

Plan for the end of your contract - Make a note of your contract end date so you can shop for the best deals when it’s time to upgrade.

What our experts say

Our Mobile and Broadband expert, Ernest Doku, says switching can save you money in several ways.

“Find out when your current mobile contract is coming to an end - then plan ahead and shop around. Those upgrade offers on shiny new handsets can be incredibly tempting however there’s often great value elsewhere.

“Switching from an ending 24-month handset contract to a SIM only contract (and keeping your existing handset) could save you £352 per year while switching to a new handset contract with a top smartphone could save you £84 per year.

“Even if you’re happy with your current provider, it’s still worth knowing what else is out there. To avoid overpaying - the key is to take action.”

Mobile phone deal and phone contract FAQs

Here are some extra things you should know about getting a mobile handset contract.

What’s the difference between a contract plan and a SIM only deal?

A SIM only deal gives you data, call and text packages without purchasing a handset, making it ideal if you have a phone you're content with. Without the handset cost, these plans are significantly cheaper than monthly contracts.

Unlike contracts, SIM only plans don't require a long-term commitment, often allowing changes or cancellations after 30 days. The lack of a lengthy commitment also means simplified credit checks, making it an efficient and fuss-free option.

Switching to a SIM only plan can reduce costs, especially compared to a pay monthly plan, as you can keep your handset without continuing the same rate after your contract ends.

Pros of SIM only:

• Usually much cheaper
• No credit check is often required
• More sustainable (less waste)

While SIM only plans are also billed monthly, "pay monthly" typically refers to a mobile phone and SIM contract.

There's no handset charge with SIM only. Pay-per-month plans, on the other hand, involve paying off your handset monthly over a 12- —or 24-month commitment.

The monthly fee for pay-per-month plans varies based on your chosen phone and includes a set amount of calls, texts, and data. For example, the iPhone 15 Pro costs £999 outright, but you can access it for less through a pay-per-month plan.

Opting for a less expensive phone, like the £429 iPhone SE, results in a lower monthly cost, potentially as little as £20.

Pros of a mobile contract:

• You can choose a new and improved phone
• Good for your credit score

Do I have to pass a credit check for a monthly phone contract?

Obtaining a new phone contract might not appear as significant as a mortgage or credit card, but it still involves a credit check.

Providers conduct these checks to ensure your ability to meet payment obligations. If they deem your credit check insufficient, they prohibit you from purchasing a contract, which can be a big shock.

Can I get a phone contract with poor or no credit?

Yes. Networks like Smarty and Voxi frequently offer SIM only deals or pay-as-you-go plans, catering to individuals with poor credit.

On the other hand, networks like TalkMobile conduct a 'soft search' on your credit file to confirm your identity without performing a full credit check.

Although handset choices may be restricted, these options provide flexibility and an opportunity to improve your credit score by responsibly managing your phone usage.

For more information, check out our guide on how to get a mobile phone deal with poor credit history.

What happens if I fail my credit check?

Getting a phone contract with poor or no credit can be tricky. If any credit check is declined, a mark is created on your credit file, temporarily complicating future credit applications or contract approvals.

Applying indiscriminately for contracts in the hopes of acceptance can further reduce your chances.

However, there's no need to panic. Take the opportunity to improve your credit score and demonstrate trustworthiness through a SIM-only deal, and you'll likely regain the ability to apply for a contract successfully.

Do I have to pay an upfront cost for a contract phone?

The upfront cost for a phone contract varies based on the device you opt for. High-end brands often require an upfront payment of at least £50, in addition to the pay monthly contract.

If the initial payment is a concern, alternatives, including contracts with no upfront fees, are available on selected phones.

Do I own my phone after the contract?

If you have a contract phone and the contract ends, you've fully paid for the handset and now own it. If you’re happy to keep your handset, you can reduce your monthly bills by opting for a SIM only or pay-as-you-go deal.

What happens if my phone breaks on contract?

Pay monthly customers typically benefit from a standard warranty for their phones. If your phone experiences malfunctions, verify if it's covered under warranty. If not, most networks provide repair services at a potentially high cost.

For handset faults, consider contacting the manufacturers directly. Apple, renowned for its exceptional customer service, allows appointments at local Apple Stores.

Regarding water damage, refer to our guide on how to fix a water-damaged phone.

How can I check when my phone contract ends?

Text INFO to 85075 to find out the information about your contract.

If you’re not sure whether you’re still in contract with your provider and if you would have to pay charges to end your contract early, you can find this out without requesting a switching code.
