You probably know how much mobile data you pay for every month, but do you know how much you actually use? I suppose, in this day and age, that’s like asking if you know how many liters of water you drink every month (“No, but I know it’s a lot”).
Mobile data usage has skyrocketed in recent years due to a variety of factors (not least the advent of autoplay features in social media apps such as TikTok). Analysis from Ericsson suggests the amount of data transferred over cellular data networks has increased more than sevenfold since 2020, with the monthly average now standing at 25GB per device in both the US and Western Europe.
But while it’s true that most of us are using more mobile data than ever, these numbers don’t quite paint the full picture — they embolden mobile operators to sell oversized data plans, and, in all likelihood, you’re paying for more data than you actually need.
That 25GB figure is skewed by smartphone users who rarely, if ever, touch Wi-Fi. We all stream HD video over 5G and occasionally set up mobile hotspots for our laptops, but some people do these things near-constantly (yes, really), using upwards of 100GB per month and disproportionately affecting the monthly average.
By contrast, Ofcom’s Communications Market Report 2025 suggests the average person in the UK uses 10.6GB of data per month, while Statista puts the equivalent US figure at between 5 and 15GB, which aligns with Ofcom’s findings. All three numbers are significantly lower than the 25GB figure quoted by Ericsson, suggesting they account for those disproportionately high usage cases (there are, of course, disproportionately low usage cases to consider too).
Unlimited mobile data plans are a popular choice among users who don’t want to be charged per gigabyte or exceed a monthly limit, but as above, these plans are rarely better options — financially speaking — than the cheaper, fixed-capacity data plans they sit above.
“Mobile operators and MVNOs [Mobile Virtual Network Operators] face higher network costs as data usage increases, which is why plans with larger allowances typically cost more,” Christian Banhans, UK Managing Director at mobile operator spusu, exclusively tells TechRadar. “However, many customers only use a fraction of their monthly data, meaning they may be paying for more than they actually need.”
“The main reason customers use less data than their allowance is psychological, as they want to avoid running out, so they often choose plans with more data than they need,” Banhans continues. “Providers also face fixed costs for each plan, alongside the costs of (often unlimited) minutes and texts. In our experience, the difference in underlying costs is relatively small compared with the pricing difference between plans.”
“Larger plans often have a lower cost per gigabyte, making them appear better value even when much of the data goes unused. This is where the gap between what customers pay for and what they use tends to be greatest.”
How to check your data usage
Banhans notes that there are several ways consumers can avoid paying for more data than they need. “The first is to sync your phone’s internal data counter to the billing cycle and track how much data you need per month, or download a standalone application to do that.”
To check your data usage on your iPhone, go to Settings, Cellular (or Mobile Service), then scroll down to the Mobile Data menu. The Current Period displayed here reflects your data usage since the last time your Mobile Data Usage Statistics were reset, which will probably be some time ago. To align that figure with your specific monthly billing cycle, you’ll want to scroll down to the bottom of the page and tap Reset Statistics on the same day each month that your billing cycle resets. You can set up a recurring Reminder to help you remember to do this.
A more straightforward solution, though, is to track your data usage through your network provider's official app — which will already be aligned with your monthly billing cycle — or use a third-party data tracking app like My Data Manager and Data Remaining.
On Samsung phones, the process is simpler. If you go to Settings, Connections, then Data Usage, you’ll see your data usage displayed in a monthly format by default. To manually align the dates to your monthly billing cycle, tap Billing cycle and data warning, then Start billing cycle on.
To see your monthly data usage on Pixel phones, go to Settings, Network & internet, then SIMs. You can choose which date you’d like your data usage stats to be reset under App data usage cycle. The process is similar for most other Android phones.
How to choose the right data plan
If, using the above methods, you find that you’re paying for more data than you actually use, you’ll want to choose a data plan that better fits your needs.
I suggest choosing a data allowance that sits a gigabyte or two above your monthly average, unless the provider in question makes it easy (and affordable) to add more data to the plan as and when needed. “It’s also important to account for occasional high-usage months, as well as factors such as Wi-Fi access and travel habits, when choosing the right allowance,” Banhans adds.
Some network providers allow you to ‘rollover’ unused data so it can be used in another month, but this shouldn’t be seen as a reason to choose a data allowance that far exceeds your real-world monthly average: “While rollover data is often presented as a solution to unused data allowances, the extra data frequently goes unused and eventually expires unless a customer’s usage varies significantly from month to month.”
In some cases, unused rollover data can be converted into money off new plans or device contracts, but these savings are often laughably small compared to the money you’ll have overspent on accruing that rollover data in the first place.
So, in summary, while unlimited and large-capacity data plans are attractive options for many people, network providers rely on consumer ignorance to sell these often excessive packages. If you put in the small amount of work required to determine your actual monthly data usage — using the methods outlined in this article — you could save hundreds over the course of a year.
