Named the Connected Heartbeat, the four-by-four-metre structure lights up in real time as calls, texts, and data connections are made on Vodafone’s network across London.
For the most vibrant display, 7:01pm is the ideal time to visit, as Vodafone’s research shows this is when people make the most calls and send the most messages.
On average, an adult in the UK sends around 28 messages a day, adding up to more than 10,000 messages a year, with Londoners being the most active phone users in the country.
Vodafone unveiled the installation and research to celebrate being named London’s Best Network by NET CHECK for the second year in a row.
Broadcaster Roman Kemp kicked off the installation’s glow, encouraging passers-by to get involved and make the heart ‘beat’ with their own digital interactions.
“I’ve lived in London for years, and it’s amazing to see my fellow Londoners connecting in real time—not just in their daily lives, but as part of a piece of art,” Kemp said.
The study also found that over two-thirds of people believe digital interactions are essential for maintaining relationships. Without mobile phones, six in 10 feel they would have less contact with loved ones.
Despite nearly 13 million voice calls being made in London each day, calling is only the fourth most popular way to stay in touch. More people prefer to communicate via WhatsApp (51%), followed by SMS (16%) and social media updates (14%).
Additionally, the research found that the average adult is part of eight group chats, with those aged 25-34 managing up to 12 different groups at once.
Artist Frankie Curtis said: “Growing up in London, I’ve always felt connected to the city and its wonderful characteristics. So, working on the Connected Heartbeat with Vodafone to put my spin on its iconic landmarks has been a joy.
“Creating each doodle for the map was a fun and immersive process, I’ve loved researching and illustrating them and capturing the essence of each area. I have friends and connections all over the city, and it is important to stay linked which helps my artistic journey.
"Seeing it all come together, with the clever tech lighting up the millions of calls made on Vodafone’s network, was really innovative. I mean, it just proves how alive and connected this city truly is!”
