O2 SIM Only Plans: The finer details
If you're looking to upgrade your mobile phone or SIM card, O2 has a wide variety of options available. You can choose from full-size, nano and micro sims. These SIMs are suitable for modern smartphones and older block phones. If you're buying a new phone, O2 SIM cards are compatible with all major carriers and can be used straight away. You can also download the priority app, which offers special perks and prizes.
The majority of O2 SIM card plans come with unlimited texts and calls, but data caps vary significantly. The most basic range has a 1GB data cap, which is incredibly cheap. However, the most popular range is between five and ten gigabytes (GB) of data, which is enough for intensive social media, maps and internet searches. Streaming and downloading up to 10GB of data is possible on these plans.
If you plan to use your O2 UK SIM card overseas, you should know that the provider has varying coverage in different areas. You will need to ensure coverage in the area you will be visiting and be aware of any limits. However, most networks do provide some roaming for free. While you can still use your O2 UK SIM card overseas, it's best to avoid roaming costs. It's also important to know the size of your O2 UK SIM card, as they can vary widely.
If you need to use a different network from the one that come with your phone, you might need to unlock it. Many phones come unlocked now, but you'll need to ask your network if you're still on a contract. Most of them are unlocked for free.
If you're on a contract, you can ask your network to unlock your phone for you, but this can be a hassle. For example, if you are using a contract with Three, then you will need to wait for the contract to finish before unlocking and switching to a SIM-only deal with another network.
Another option is to go from contract to a Three SIM only deal, i.e. with the same network.
