O2 is one of the four main mobile networks in the UK, and their service is usually quite reliable. The mobile network provider offers 5G at no extra cost to their pay-monthly customers, and customers also enjoy a decent 4G service accompanied with perks such as VoLTE and WiFi Calling. Their plans include free O2 WiFi in over 16,000 locations, and if you’re also a Virgin Media Broadband customer, you’ll get double data and your broadband service will be upgraded to the next level.
They also provide a contract-free PAYG service, but you must purchase a 30-day bundle and renew it regularly to benefit from it.
All O2 plans, be it pay monthly or PAYG include O2 Priority, a great entertainment scheme that gets you free prize rewards, discounts, early access to event tickets, and more.
If you’re happy with your phone and don’t mind a long-term contract you can save a decent amount of money with O2’s SIM only contracts. You can also keep your number if you’re switching from another mobile network. All O2 contracts include O2 Priority which gets you the VIP treatment, with freebies and prize draws. You can also enjoy free O2 WiFi wherever available. O2’s SIM only contracts are set up for 5G, provided you have a 5G ready phone and you’re in an area with O2 5G. You’ll also need a 5G SIM if you don’t have one yet.
Some of the more expensive SIM only plans from O2 also include free entertainment options such as 6 months free Disney +, Amazon Prime Video, and more.
You can also supercharge your data allowance if you’re also a Virgin Media broadband customer. Supercharging your O2 SIM only plan will get you double data, and your broadband speed will be bumped up to the next tier.
The network’s Pay As You Go service is commitment-free, meaning there are no credit checks to pass or contracts involved. Plus you can earn cashback when you top up with O2 Rewards and get access to Priority. Having said that, you still have to purchase a 30-day bundle and then top up the right amount each month. O2 doesn’t have the old-school PAYG system, where you can just top up and use your credit as you go.
O2 has a wide range of mobile devices for you to choose from, including 5G ready handsets. If you are looking to get a pay monthly phone deal you can purchase devices from top tier manufacturers such as Apple, Samsung, Huawei, and Sony. You can also trade in your old phone and save on your monthly bill. However, you’ll have to pass a mobile phone credit check.
If you wish to pick a handset combined with a PAYG SIM, you’ll find more budget-friendly options such as Alcatel, Nokia, and ZTE.
O2 allows you to separate your airtime bill and phone bill and calls it O2 Refresh. This way you can upgrade your device whenever you want, provided you’re willing to pay the full price of your current device first.
You can also create your own phone plan; we’ll cover it below.
O2’s Custom Plans lets you choose how much you want to pay upfront, and spread the cost of your monthly bill. Basically, you’re in control of your contract. You may spread the balance for up to 36 months and keep your monthly cost down, or alternatively, you may choose as little as three months and pay off the cost of the handset quicker.
You can also choose from a range of O2 Extras, such as Amazon Prime Video, Audible, Calm, and a few more. Students get a 20% discount when choosing a custom SIM plan from O2.
You can also purchase a refurbished phone from O2 and save some cash. O2 brands their refurbished phones as “Like New Devices” and they come with a 12-month warranty. The carrier makes sure all these devices undergo a thorough quality check first before they’re on sale. Plus, you can return them within the first 14 days of purchase if you’re unhappy.
You can combine a refurbished phone deal with either a pay monthly contract or a PAYG SIM deal. It’s up to you
