This comprehensive review examines O2 from every angle, covering network coverage, plan options, pricing, customer service, unique features, and how it compares to competitors. We'll dive deep into O2's strengths and weaknesses, help you understand the different plan types, and provide practical guidance for choosing the right O2 plan for your needs. Whether you're considering switching to O2 or evaluating your current provider, this review will help you make an informed decision.
Understanding O2
O2 operates as one of the UK's four major mobile network operators, alongside EE, Vodafone, and Three. The company provides mobile services including voice, text, and data, as well as fixed-line broadband and TV services in some areas. O2 is known for its extensive network infrastructure and the O2 Priority loyalty program, which offers exclusive deals and experiences to customers.
Network Infrastructure
O2 operates its own network infrastructure, which means it has direct control over network quality and coverage. The network covers 99% of the UK population with 4G services and is expanding 5G coverage in major cities and towns. O2 also has roaming agreements with other networks to fill coverage gaps, particularly in rural areas where building new infrastructure may be less economically viable.
O2's network performance is generally strong in urban areas and along major transport routes. The company has invested significantly in network infrastructure, including the rollout of 5G services. However, network quality can vary by location, and some customers report issues with coverage or speeds in specific areas. It's always worth checking O2's coverage checker for your specific location before committing to a contract.
Network Coverage and Performance
Network coverage is one of the most important factors when choosing a mobile provider. Understanding O2's coverage and performance helps you determine whether it will meet your needs.
4G Coverage
O2 provides 4G coverage to 99% of the UK population, making it one of the most extensive networks in the country. 4G coverage is generally strong in cities, towns, and along major roads and railways. Rural coverage can be more variable, though O2 has made efforts to improve coverage in less populated areas.
Network speeds on O2's 4G network are generally competitive, though actual speeds can vary significantly depending on location, time of day, and network congestion. In areas with good coverage, users typically experience speeds suitable for streaming, browsing, and using apps. However, some customers have reported issues with internet speeds and service reliability, particularly in certain locations or during peak times.
5G Coverage
O2 is actively rolling out 5G coverage across the UK, with service available in many major cities and towns. 5G provides significantly faster speeds and lower latency compared to 4G, making it ideal for data-intensive activities like video streaming, gaming, and video calls. However, 5G coverage is not yet universal, and availability depends on your specific location.
To access 5G, you'll need a 5G-compatible phone and a plan that includes 5G access. O2 provides coverage maps showing 5G availability, and the network is continuing to expand. If 5G is important to you, check whether it's available in your area before signing up.
Plan Options and Pricing
O2 offers a variety of plan options to suit different needs and budgets. Understanding the different plan types helps you choose the right option.
SIM-Only Plans
SIM-only plans are ideal if you already have a phone or want to buy one separately. O2's SIM-only plans typically start from around £10-15 per month for basic data allowances (1-4GB), with prices increasing for larger data allowances. Unlimited data plans are available, typically costing £30-40 per month. Plans are available on 1-month, 12-month, or 24-month contracts, with longer contracts often offering better value.
SIM-only plans include unlimited calls and texts, with data allowances varying by plan. O2 often runs promotions offering additional data or discounts, so it's worth checking for current offers. These plans provide flexibility and can be more cost-effective than phone contracts if you don't need a new device.
Phone Contracts
O2 offers phone contracts that combine a device with an airtime plan. These contracts typically run for 24-36 months and include the cost of the phone spread over the contract period. Monthly costs vary significantly depending on the phone model and data allowance, typically ranging from £30-100+ per month.
O2 Refresh is a flexible contract option that separates your phone cost from your airtime plan. This allows you to upgrade your phone earlier by paying off the remaining device balance, while keeping your airtime plan. Refresh contracts provide more flexibility than traditional contracts, as you can upgrade after paying off at least 50% of your device cost.
Data Allowances
O2 offers a range of data allowances, from basic plans with 1-4GB to unlimited data plans. Most users find that 10-20GB is sufficient for typical usage, while heavy users may need unlimited data. O2 also offers data rollover on some plans, allowing unused data to carry over to the next month.
If you exceed your data allowance, O2 will typically slow your connection speed rather than charge overage fees on many plans. However, some plans may charge for additional data, so it's important to understand your plan's terms. Unlimited plans eliminate this concern but come at a higher monthly cost.
O2 Priority: The Loyalty Program
O2 Priority is one of the network's most distinctive features, offering exclusive deals and experiences to customers. Understanding Priority benefits helps you evaluate O2's overall value proposition.
What Is O2 Priority?
O2 Priority is a loyalty program that provides exclusive offers, early access to events, discounts, and special experiences. Benefits are available through the O2 Priority app and vary depending on your plan. Priority has been a significant differentiator for O2, offering value beyond just network services.
Priority benefits include 2-for-1 cinema tickets on Tuesdays, restaurant discounts, early access to concert and event tickets, exclusive experiences, and retail discounts. The program has partnerships with various brands and venues, providing ongoing value to O2 customers. Some benefits are available to all O2 customers, while premium benefits may require specific plans.
Priority Benefits Value
The value of O2 Priority depends on how much you use the benefits. If you regularly go to the cinema, attend concerts, or dine out, Priority can provide significant savings and exclusive access. However, if you don't use these benefits, Priority may not add much value to your plan.
Priority has been particularly popular for early access to concert tickets and exclusive events. The program has evolved over time, with benefits changing and new partnerships added. It's worth checking current Priority benefits when evaluating O2, as the program continues to evolve.
Customer Service and Support
Customer service quality is an important consideration when choosing a mobile provider. O2's customer service has received mixed reviews from customers.
Support Channels
O2 offers customer support through multiple channels: phone, online chat, in-store, and social media. The company has retail stores across the UK where you can get in-person support, purchase devices, and manage your account. Online support is available through the O2 website and app.
However, customer service experiences can vary. Some customers report positive experiences with helpful and responsive support, while others have experienced issues with service reliability, internet speeds, and customer service responsiveness. There have been complaints about non-functional services, delayed responses, and difficulty resolving issues.
Service Reliability
Some customers have reported issues with O2's service reliability, including problems with internet speeds, TV services (where applicable), and network connectivity. These issues can be frustrating, especially when they persist despite contacting customer service. However, many customers have positive experiences with reliable service.
Service quality can vary significantly by location, and issues may be more common in certain areas or during network upgrades. If you're considering O2, it's worth checking coverage and asking people in your area about their experiences with the network.
International Roaming
O2 offers international roaming services, though policies and costs have changed over time, particularly regarding EU roaming after Brexit.
Roaming Policies
O2's roaming policies vary by destination and plan. Some plans include EU roaming, while others require add-ons. O2 Travel add-ons provide data, calls, and texts in various destinations outside the EU. Roaming charges and included allowances vary, so it's important to check current policies for your destination.
After Brexit, EU roaming policies changed for UK networks, and some plans may now charge for EU roaming or require add-ons. It's essential to understand your plan's roaming terms before traveling to avoid unexpected charges. O2 provides information about roaming costs and policies on their website.
