TLDR
Travel-tech start-up LeafySIM has launched destination-specific prepaid eSIM data plans, letting travellers buy and install a digital SIM profile before they leave home. Juniper Research puts average eSIM data costs at $5.50 per GB versus $8.57 per GB on traditional carrier roaming, a 35% difference. The travel eSIM market is expanding sharply, with Juniper forecasting global users will grow from 40 million in 2024 to more than 215 million by 2028. Kaleido Intelligence projects retail spending on travel eSIM services will top $3.3 billion by 2025, nearly 165% above 2023 levels.
KEY TAKEAWAYS
What LeafySIM launched and what its founder said
LeafySIM announced destination-specific prepaid eSIM travel data plans on 27 July 2026, pitching the product as an end to roaming bill shock for international travellers.[1] The platform lets travellers purchase, install and activate a digital SIM profile before departure, removing the need to hunt for a physical SIM card on arrival or accept unpredictable carrier roaming rates.[1]
Vinceramos Xavier, LeafySIM's founder, kept the pitch simple. "Travelers plan flights and hotels in advance. Mobile data should be no different. LeafySIM lets travelers arrive connected, without roaming bills or airport SIM card queues waiting for them," Xavier said.[1]
How a prepaid travel eSIM works
A traveller selects their destination, buys a data plan online and receives a QR code, which they scan to install a digital SIM profile directly onto any compatible smartphone.[1] The device's dual-SIM capability keeps the home carrier active for calls and texts while routing data through the local plan, so there is no need to swap anything or lose the original number.
Xavier framed the product as part of a broader shift toward end-to-end digital trip planning. "Travelers today plan everything digitally -their flights, accommodation, experiences. Connectivity should be no different. LeafySIM was built around the idea that mobile internet abroad should be something travelers sort before they leave, not something they scramble for after they land," Xavier said.[1]
The roaming-bill problem it is trying to solve
International mobile roaming has long produced unwelcome surprises. Default roaming plans from major carriers charge per-gigabyte rates well above domestic data costs, and background app activity, map updates, cloud syncs and push notifications, racks up charges automatically before many travellers realise what is happening.[1]
Travellers using eSIM plans paid an average of $5.50 per GB of mobile data compared with $8.57 per GB on traditional roaming, according to Juniper Research, a 35% cost difference.verifiedVerified Source: businesswire.com[2] On a typical week-long trip consuming 5 GB of data, that gap works out to roughly $15 saved before a single coffee has been bought abroad.
How eSIM travel data compares on price
The Juniper Research figures are vendor research, commissioned by a firm with commercial interest in the eSIM market, and should be read in that context. Still, the directional case for prepaid digital SIM plans over carrier roaming is consistent with independent pricing comparisons that have circulated across the travel community for years.
Kaleido Intelligence projected that retail spending on travel eSIM services would reach $3.3 billion by 2025, representing a near 165% increase on 2023 levels.verifiedVerified Source: kaleidointelligence.com[3] That trajectory suggests the savings pitch is landing with travellers, not just analysts. LeafySIM enters a market already drawing serious consumer dollars, which raises the competitive stakes as much as it validates the category.
The bigger picture: how fast the category is growing
Juniper Research forecast that the global number of travel eSIM users would grow from 40 million in 2024 to more than 215 million by 2028, a 440% rise over four years.verifiedVerified Source: businesswire.com[2] Two structural forces are driving that curve: device compatibility and travel volumes.
GSMA Intelligence's Operator Smartphone Survey found that roughly 60% of smartphone unit sales would be eSIM-compatible by 2025, widening the pool of travellers who can use the technology without buying new hardware.[4] UN Tourism's World Tourism Barometer recorded 1.4 billion international tourist arrivals in 2024, an 11% rise on 2023 and near full recovery to pre-pandemic levels.[5]
More people crossing borders means more phones hunting for a data signal abroad. LeafySIM's launch on 27 July 2026 positions it to capture a slice of that demand as device compatibility crosses the 60% threshold and traveller numbers keep climbing.
