Understanding the O2 2025 Price Increase
Like many major UK network operators, O2 annually adjusts its prices for pay-monthly customers. This increase is typically linked to the Retail Price Index (RPI) or Consumer Price Index (CPI) rate of inflation, plus an additional percentage (often around 3.9%). While the exact figure for 2025 will be confirmed based on official inflation rates, customers can expect another noticeable jump in their monthly payments.
According to the UKâs communications regulator, Ofcom, millions of mobile customers are affected by these mid-contract price rises each year. For the average user, this can mean paying significantly more over the remainder of their contract than they originally signed up for. This practice highlights the inflexibility of traditional contracts and the financial penalty for loyalty.
Is eSIM a Good Alternative to O2?
If the thought of another price hike has you frustrated, itâs the perfect time to explore more modern and cost-effective solutions. Instead of being locked into a rigid 24-month contract, imagine having the freedom to choose exactly how much data you need, for how long you need it, without any strings attached. This is the freedom that eSIM technology offers.
An eSIM (embedded SIM) is a digital SIM card built directly into your phone. It allows you to activate a cellular plan without needing a physical SIM card. For UK users, this is a game-changer.
Key Benefits of Switching to an eSIM:
- Massive Cost Savings: eSIM plans are often significantly cheaper than traditional contracts because they cut out overheads. You pay only for the data you need.
 - Ultimate Flexibility: Choose from short-term or long-term data packages. There are no contracts, no credit checks, and no surprise price hikes. You are in complete control.
 - Instant Connectivity: Purchase and install your plan in minutes from anywhere. No more waiting for a physical SIM to arrive in the mail.
 

With Yoho Mobile, this flexibility is paramount. You can build your own flexible plan tailored to your specific needs, ensuring you never pay for data you donât use. Itâs the ideal way to avoid the O2 price increase in 2025.
Finding the Best UK eSIM Plan for You

Frequently Asked Questions (FAQ)
Can I switch to an eSIM if Iâm still in my O2 contract?
Yes, you can. Your phoneâs eSIM slot is separate from the physical SIM slot. You can use a Yoho Mobile eSIM for affordable data in the UK while keeping your O2 SIM for calls and texts to retain your number. This is a great way to cut your mobile data bill without breaking your contract.
Is an eSIM a good alternative to O2 for cheap mobile data in the UK?
Absolutely. eSIMs from providers like Yoho Mobile are one of the best alternatives. They offer competitive pricing, contract-free flexibility, and a wide range of data packages, making them an ideal solution for anyone looking to save money on mobile data after the O2 price rise.
Will I lose my phone number if I switch from O2 to a data-only eSIM?
No. A data-only eSIM does not come with a phone number. You can continue to use your existing O2 physical SIM in your phone to make and receive calls and texts with your current number. The eSIM will simply handle all your mobile data needs at a lower cost.
How can I avoid the O2 price increase in 2025 without changing my number?
A perfect strategy is to use a dual SIM setup. Reduce your O2 plan to the lowest possible tariff (or a talk/text-only plan if available) and purchase a cost-effective data-only eSIM from Yoho Mobile. Youâll keep your number and slash your monthly data costs, completely sidestepping the price hikeâs impact.

The O2 price increase for 2025 doesnât have to mean a bigger dent in your wallet. Itâs a clear signal that the old way of buying mobile data is becoming outdated and expensive. By embracing flexible, affordable, and user-friendly technology like eSIMs, you can take back control.
