How Does O2 Work?

O2 is the second-biggest telecommunications provider in the UK. With 23 million subscribers, the company offers extensive 4G and 5G coverage throughout the country, with wide-ranging, stable service. In addition to its huge slate of different offerings, tailored to virtually any kind of mobile phone user, its plans include a wide range of perks, including priority access to presale tickets for places like the O2 and O2 Academy and free coffee, food deals, and cinema tickets. Overall, it’s one of the leading providers in the country for a reason: it’s been around since 1984, its network is accessible by 99% of UK residents, and it's known for solid customer service and flexible offerings.

Chief among those flexible offerings are its pay-as-you-go plans, which help users pay less while avoiding being locked into sticky contracts or facing unexpected costs. These prepaid plans allow you to purchase a bundle of data up front, inclusive of talk and text, and use it until you feel like topping it up again. This ensures that you don’t pay for anything extra, use only what you want, and switch networks or providers whenever you find a better deal or move out of the country. It’s ideal for travellers and those who simply value finding the best deal. And if you do choose to go with a prepaid plan, you’ll need a way to keep your balance topped up. Mobiletopup.co.uk is built to allow you to seamlessly add funds to your balance from anywhere in the world, delivering a top-up code to your inbox within seconds. You can top up your balance with the confidence that it’s secure, using a wide variety of payment methods. If all you’ve come to do is top up, below is a guide to using mobiletopup.co.uk to do exactly that. But first, a bit about the best plans O2 has on offer, and why prepaid is particularly attractive for most customers.

Pay as you go should be the go-to option for most users

O2 offers a huge range of plans, including prepaid and monthly tariffs of various sizes. The thing is, if you boil down these bajillions of options into a raw GB-per-pound equation, it reveals which are actually the best. First, though, you should consider how much data you actually need. According to Ofcom, the average user chews up only 9.9 GB of data per month. That’s way less than the vast majority of plans and packages offered by O2. We’ll skip the preamble and say that if you only use 10GB per month of data, your best bet is O2’s 25GB package for just £15. That’s only £1.50/GB used – and if you need more, you can simply purchase more top-up credit. If you use less, that data rolls over to use whenever you need!Of course, if you need roaming or are a power user that uses way more data than average, the equation changes. Roaming charges are arguably better on the premium monthly plans, and the cheapest one that offers unlimited data is only £16 a month, rising to £32 after six months. It’s clear that for the vast majority of users, prepaid is best—especially since it helps you avoid sticky contracts. If you ever feel dissatisfied with O2’s service, or find a better deal elsewhere, you can use up your remaining balance and head for greener pastures. The one downside to prepaid is that you need to keep abreast of your balance, and make sure it stays topped up. Luckily, mobiletopup.co.uk makes it easy. Here’s how to use it.
