India is the country with the third biggest eSIM savings of over £190. EE charges the most for data roaming in India, where customers are set back a huge £205.50 for a month of data roaming. To save you over £190, switch to an eSIM from Airalo at just £10.75 for 3GB of data.

How to save money on your mobile bill while travelling

See what eSIMs can offer you – eSIMs are well worth considering. A local eSIM bundle is typically cheaper than data roaming bundles from the big four networks, or when paying per MB when in foreign countries. Check out the above to see where you can save the most money on mobile roaming by using an eSIM.

Keep your eye out for free Wi-Fi – Free Wi-Fi is everywhere these days, from hotels, restaurants and bars to cafes and public transport. Some areas, such as airports, may charge you a small fee for a Wi-Fi connection. But this will often be cheaper than paying for additional mobile data.

For data-intensive tasks, such as uploading your holiday pictures to social media or video calling home, it’s a good idea to find free Wi-Fi if you can. But remember to make sure any network you join is safe and secure.

If you want some additional security, you could also consider purchasing a VPN. This will provide a private connection between your device and the websites you visit and add an extra layer of security that encrypts your data.

Turn off auto updates – Many phones have settings that auto-update your phone’s software and apps. This can be especially data-heavy, particularly if you are travelling for a while and you have multiple updates to action. Turning off auto-updates can help you to save a lot of data and minimise your roaming expenses. Alternatively, you can set your phone settings so that auto updates only take place when you are connected to Wi-Fi.

Download content before you travel – Before travelling, download any films, TV shows, e-books or music you might want to access while you’re away. This can help to save you a lot of data should you want to consume your favourite media on the go.
