One of O2’s main promotions - its O2 Priority ticket scheme, which sees O2 customers exclusively granted priority access to tickets to shows in a variety of genres - quickly became popular with music fans, young and old. However, when you search for the best O2 mobile contracts you don’t have to be a gig worshipper to make the most of O2’s 5G network coverage, unlimited data packages or sim only deals. The company offers a variety of mobile contracts to suit every budget, including iPhone lovers, Android fans and bargain hunters of all kinds.

As 5G rolled out further across the country the number of O2 5G plans increased alongside, with the company offering 5G contracts from major manufacturers like Apple, Samsung and Huawei. All O2 5G deals vary in terms of data and budget, with newly released handsets often taking the lead as the most expensive.

Undoubtedly the cheapest way to go when looking to switch up your mobile contract is through a sim only package. The O2 sim only deals featured here include a variety of data packages that might surprise in terms of affordability. Deciding which is the best sim only O2 plan depends on both your budget and your data requirements, but you can pick up a useful amount of data without huge outlay thanks to O2’s drive to be competitive with MVNO networks like Giffgaff and iD Mobile. Of course, how much data you need depends on how you use your data. Streaming services like Netflix and Sky Sports will require a more generous data contract than music or podcast services like BBC Sounds, for example.

If iPhones are used by roughly half of smartphone users in the UK it doesn’t take a mathematician to realise the other half will be using Android. The universality of the Android operating system means that no matter which O2 Android package you choose, you will be easily able to switch from Xiaomi to Huawei, or from Google to Sony. Each manufacturer has its nuances and different modes of operation, but the Android OS and the use of Google apps like Gmail and Google Maps mean that these O2 Android deals will make the transition to your new handset seamless.

O2 Overview

O2 was born as BT Cellnet in the early 1990s, a majority-owned subsidiary of BT. BT rebranded the company to O2 in 2002 and then promptly sold it to Spanish telecoms giant Telefonica in 2006 for a cool £17.7bn. Fast forward eight years later and BT courts both O2 and EE, eventually plumping to spurn its progeny and instead turning EE into the biggest mobile network in the UK. The story has the hallmarks of a soap opera love triangle, but the fact that failed courting hasn’t held O2’s brand back is testament to the popularity of the network as much as it is to the variety and quality of the O2 phone packages on offer.

O2’s size, history and reputation means that it can offer some of the best monthly plans available on the world’s most popular smartphone handsets, including Apple, Samsung and Huawei. Couple that with an expansive 5G network that makes the most of O2 unlimited data deals and a host of sim only packages and its small wonder that O2 is hot on the heels of EE as the nation’s favourite network.
