From weekend city breaks to full-time nomads.
Maya Okonkwo
Digital nomad
"Landed in Lisbon, opened my maps in the taxi, done. No hunting for a kiosk, no swapping SIMs. SimSIM was live before I found the exit."
Diego Ferreira
Frequent flyer
"I set up the eSIM the night before and kept my work number active the whole trip. Ran low over the weekend and topped up in two taps."
Ana Sørensen
Backpacker
"Three countries in two weeks and I paid one clear price up front. No roaming bill waiting for me when I got home. That is the whole reason I switched."
