When it comes to sim only packages, O2 has written the rulebook. As one of the most established UK mobile networks - and one of Europe’s biggest networks, too - the O2 sim only deals with serious pedigree. Thanks to its extensive 5G network, smartphone users can expect a range of 5G sim deals and unlimited data packages on both 4G and 5G networks. O2 even competes with MVNOs like Tesco Mobile, Giffgaff and Sky Mobile (with all of whom O2 partners to provide its network) by offering a selection of cheap packages to provide a different option for customers who want to use the O2 network but are on a strict budget. All O2 sim only deals also qualify for its O2 Priority Rewards scheme, giving you more back for being a loyal O2 customer.

O2 5G Enabled Sim Only Tariffs

O2 is all about 5G mobile packages. The network launched its 5G service just months after the EE network began the UK rollout of the world’s fastest yet mobile network. It has been expanding the UK infrastructure ever since, and expanding the catalogue of O2 5G deals it provides alongside. 2020 saw O2 introduce a range of 5G packages to coincide with the various new handsets that were released by the world’s top manufacturers, like the iPhone 12 and Samsung Galaxy S20. This range of O2 5G plans include options from 2GB of 5G stretching up to a mouthwatering 250GB and even unlimited 5G data offers. 

O2 Unlimited Data Sim Only Tariffs

Whether you are using a 5G enabled handset or a 4G phone, there are a number of O2 unlimited data packages to choose from. Unlike most other mobile networks, O2 does not advertise its 5G plans separately to its 4G contracts. Whether you are on the hunt for 2GB or an unlimited data contract, O2 structures its deals in exactly the same way. First, you select your plan, then choose whether you want 4G or 5G. This simplified process saves you having to trawl through oodles of 5G contract offers to select the right one. O2 also details any promotional offers it is running once you have chosen your package, with free gift promotions in the past including free Disney+ months or Amazon Prime membership.

Along with its all singing and dancing 5G unlimited data plans you can also find cheap O2 sim only packages if you are more budget focussed. The cheapest O2 plans start from £12 per month, and make their way up from there. They might not be as affordable as the likes of Giffgaff or Tesco Mobile but they give you access to the O2 rewards scheme, which sees you earn 5-10% back every three months. You can then use this credit against your phone bill - thereby making it even cheaper - or use it towards high street vouchers or theatre and gig tickets. The O2 Priority Rewards scheme is effectively a thank you from O2 for your custom, and is available to customers on O2 pay monthly packages as well as sim only deals.
