Types of O2 Unlimited data plans

O2 is a well-known mobile network provider in the UK, so it is important that it allows clients to choose from a range of deals that offer unlimited data.

O2 provides two options for choosing a smartphone with unlimited data and this can be done online.

A monthly plan can be cheaper in the long run and offers better mobile phones, but pay as you go unlimited data deals offer a more flexible payment option.

Customers should choose the best deal that suits their financial situation.

However, if clients want a SIM only deal they have the option of choosing an unlimited data plan on a 12 or 18-month contract.

The SIM only unlimited data deals start from £33 a month, so find a plan that is in your budget.

What smartphones offer O2 unlimited data?

Fortunately, for clients who want unlimited data, will have the ability to choose from some of the latest smartphones in the UK.

For example, the iPhone 11 Pro Max, with a capacity option of 64GB or 256GB and the Super Retina XDR display, will be perfect for Apple lovers who want unlimited data.

For clients who prefer Samsung, can get the Galaxy Note10 Plus 5G ready, which combined with unlimited data, is a great combo.

However, these plans are offered to monthly customers because the phones are more expensive, so it allows clients time to pay it off.

There is an option to pay these phones under a pay as you go contract, but it is not initially part of the O2 pay as you go section.

For pay as you go deal members, they can get mobile phone brands such as Huawei, Sony, Motorola, Doro and Alcatel.

Does O2 5G offer Unlimited Data?

O2 customers are fortunate to have a mobile network provider that allows them to experience the best data technology in the world.

5G is offered to O2 members and they can get unlimited data deals, but they must have a mobile phone that is capable of achieving 5G technology.

For example, the Galaxy Note 10 Plus is 5G ready and it is an unlimited data deal.

Also, clients must be in a 5G-coverage area and, since the rise of O2 5G, there has been an increase of towns and cities that offer 5G.

To be specific, there are 75 towns and cities that provide the best data technology, including major cities such as London, Manchester and many more.

O2 5G Unlimited data deals

O2 does offer 5G unlimited data deals but it depends if the customer has a mobile phone that is capable of acquiring 5G data.

O2 will ask you if your phone is 5G ready before you make a purchase on a SIM only deal; therefore, it is important to get a 5G ready smartphone.

However, there are Samsung Galaxy mobile phones that offer unlimited data and are 5G ready.

It's a bonus for anyone to get 5G because it's on another level compared to 4G. For example, 4G will struggle to give quality signal in a crowded place, whereas 5G will not have this problem.

Also, there are no limits to the speed of 5G, so movie bingers and gamers will enjoy high standard Internet connection.


From a pricing aspect, O2 unlimited data deals are worth it if you are a heavy data user.

For example, movie bingers, online gamers or people who use their smartphones to watch sports will benefit from unlimited data.

Adding 5G data technology is the icing on the cake because you'll get excellent service with unrivalled Internet speed.
