Simline vs your carrier's roaming plan
Carrier roaming is usually the most expensive way to use data abroad. Here's the math, plus when roaming still makes sense.
Local-grade data prices in 150+ countries. Same network as locals, none of the roaming markup.
Convenience: you don't have to install anything. But you pay 5–20x more than a Simline data plan in the same country.
Carrier roaming is the easy default, and the most expensive choice you can make. Spend two minutes installing Simline and pocket the difference.
Frequently asked questions
Is a travel eSIM cheaper than roaming?
Almost always. Roaming typically runs $10–$15 per GB, while a Simline data plan starts from €0.99 on the same local networks in 147+ countries – often 5–20x cheaper.
Is an eSIM a good alternative to roaming?
Yes – it's the same local 4G/5G networks without the roaming markup or bill-shock risk. You install it before you fly with a quick QR scan and keep your usual number for calls and texts.
Do I need to turn off roaming when I use a Simline eSIM?
Set the Simline eSIM as your data line and turn data roaming off on your primary SIM. You'll still receive calls and texts on your usual number while paying local data prices.
