eSIM vs roaming: everything you need to know in 2026
Stop overpaying for data abroad. eSIMs have changed the rules of the game.
What is an eSIM
An eSIM is a digital SIM built into your phone. You do not need to buy a physical card or hunt for a shop when you land. You buy a plan online, scan a QR code and have data instantly. Most phones from 2020 onwards support it (iPhone XS+, Samsung S20+, Google Pixel 3+).
How much roaming costs in 2026
Within the EU, roaming is free on your normal plan (the "Roam Like at Home" rule). Outside the EU is where it hurts: data can cost €5-15/MB. A day of normal use can mean €30-50 in roaming. This is where an eSIM saves you.
How much an eSIM costs
Plans vary by destination and data. For example: 1GB for Japan is around €4.50, 5GB for Europe around €12, or 10GB globally around €25. Compared with roaming, the savings are huge. Yesim and DrimSim offer similar plans with different coverage.
Which provider to choose
Some providers have very wide coverage (200+ countries). Yesim stands out for unlimited plans. DrimSim offers a physical SIM + eSIM option. Our recommendation: compare in the eSIM section of Flamaz for your specific destination.
Practical tips
Activate the eSIM before you travel (you need WiFi to scan the QR code). Turn off data on your main SIM to avoid roaming charges. Keep the QR code saved in case you need to reinstall. And remember: within the EU you do not need an eSIM, your Spanish plan works the same.
