Most people pick a mobile plan based on habit or headline price. They spot something that looks like good value and sign up. A year or two later, they’re still on the same plan without ever checking whether it suits how they actually use their phone. The result?
Here are the biggest misconceptions around mobile plans in the UK.
Unlimited Data Sounds Better Than It Usually Is
Unlimited plans have grown in popularity. According to Ofcom, unlimited data tariffs made up 13% of mobile plans in 2023, up from 5% in 2019. The appeal is obvious: you never have to worry about running out. But for most people, that peace of mind comes at a cost they don’t need to pay.
According to Ofcom, over two-thirds of mobile users in the UK never fully utilize their monthly data allowances during their contracts. The median usage sat at around 2.7GB per month in 2023, and even with usage rising, Ofcom’s Communications Market Report puts the average at 10.6GB per month.
If your typical month involves social media, messaging, some browsing and the occasional video, a mid-range allowance will cover you. Paying extra for unlimited is, for most people, paying for a safety net you’ll never fall into.
Big Networks Don’t Always Mean Better Coverage
There is a widespread assumption that sticking with one of the UK’s major network operators gives you better coverage than going with a smaller provider. That’s not always the case.
Lebara operates using Vodafone’s infrastructure, offering extensive 4G coverage across nearly all of the UK, with 5G gradually rolling out in more towns and cities at no extra charge. Other MVNOs like Giffgaff and SMARTY work the same way, but run on different networks.
The best way to go about it is to check which network an MVNO runs on, then use Ofcom’s coverage checker to confirm signal in the areas where you spend most of your time. If the coverage is there, there’s no practical reason to pay more for a big-name brand.
You Should Be Paying for What You Actually Use
A mid-range allowance in the 20GB to 30GB bracket covers the vast majority of average users comfortably. The best 30GB SIM-only plans are now so much more affordable than the standard, 2-year contracts from the big networks, it’s a no-brainer which one you should go with.
For instance, Lebara’s 30GB monthly rolling plan is currently priced at £10 per month, with unlimited UK minutes and texts and 100 international minutes included. There is no contract, and you can cancel with 30 days’ notice. Unlike many larger networks, Lebara does not apply annual price rises and did not increase prices in April 2025 when several major providers did.
Contracts Are Almost Never the Cheaper Option
Contracts feel cheaper because the monthly cost bundles in your handset repayments. When you analyze the costs, it often turns out you’re paying significantly more for a phone than if you had purchased its components individually
Ofcom’s pricing research has confirmed the gap consistently. A 2024 study revealed that purchasing a phone outright and opting for a SIM-only plan generally costs about 25% less, resulting in monthly savings of roughly £7, or approximately £170 annually a typical two-year contract. Keep in mind that this gap is likely to keep widening, as many MVNOs have pledged not to increase prices in the near future, while the big networks are still consistently raising their prices year after year.
Under Ofcom rules that came into force in January 2025, providers must also state any planned price increases in pounds and pence upfront before you sign, making it easier to compare the true long-term cost of any deal.
You Probably Don’t Need a New Phone
The mobile industry has long been built around a two-year upgrade cycle, but most modern smartphones last considerably longer. UK consumers are increasingly keeping their devices for three years or more. Handsets from three or four years ago, such as the iPhone 13 or Samsung Galaxy S22, still handle everyday tasks without meaningful issues.
To Summarise
Check your actual data usage, consider whether you need a new phone, and compare SIM-only options when your contract ends. A 30GB rolling plan with no price rises will cover most people without the premium attached to unlimited bundles or branded handset deals. For the majority of users, it’s a simple way to pay less for the same experience.
