From his bustling Sydney office, Simify co-founder Aidan Butler shares his passion for disrupting outdated norms in the tech world as he discusses the revolutionary impact of eSIM technology on the modern traveller.

“eSIMs are a game-changer for travellers, offering the best of both worlds,” Aidan says. “Rather than switching phone numbers, you can use a travel eSIM for unlimited roaming data from the likes of Simify, all while keeping your home number active for things like receiving verification codes from your bank.”

For years, international travellers have faced the stress of juggling multiple SIM cards, switching phone numbers, rationing precious mobile data, and hunting for potentially insecure free Wi-Fi connections. Aidan recognised this frustration and saw an opportunity to make a change.

Simify, founded in 2018 by Aidan and fellow entrepreneur Mac Steer, was born out of a shared frustration with the expensive and restrictive roaming packages offered by major telcos. The duo tapped into a growing demand for a better deal, quickly growing their business to serve more than 300,000 satisfied customers.

Now Simify offers mobile coverage in more than 150 countries, providing unlimited data for up to 90 days without extra fees.

The simplicity and freedom offered by eSIMs are transforming the travel experience. “You shouldn’t have to use your smartphone like a dumbphone when you’re overseas, just because you’re terrified of chewing through your measly data cap,” he adds.

“The big telcos will tell you, ‘It’s easier to just stay on our plans when travelling,’ but easier for who? Travellers shouldn’t have to stress about data limits when they’re overseas. They should be able to relax and use their phone just like they do at home.”

Aidan’s vision for Simify extends beyond simply providing a service; it’s about enhancing the travel experience itself. As the world becomes more interconnected, the ability to stay seamlessly connected is no longer a luxury but a necessity.
