eSIM vs Roaming — Cost Comparison 2026
Within the EU, "roam like at home" keeps roaming affordable. Outside the EU, pay-as-you-go roaming from European carriers typically costs €5–15 per day or €5–12 per GB — while a travel eSIM costs a fraction of that. Real examples:
| Destination | Typical carrier roaming* | eSIM from OWL eSIM |
|---|---|---|
| Turkey | €6–12/day day-pass or ~€10/GB | from ~$2/GB |
| USA | €6–15/day day-pass | from ~$2.50/GB |
| Thailand | €8–15/day or ~€12/GB | from ~$2/GB |
| UAE | €10–15/day | from ~$3/GB |
| Japan | €8–15/day | from ~$2.50/GB |

FAQ
Is roaming free in the EU?
EU "roam like at home" lets you use your domestic plan in EU/EEA countries at no extra cost, within fair-use limits. Turkey, the UK (some plans), USA and Asia are NOT included — that's where an eSIM saves the most.
How much cheaper is an eSIM than roaming?
Outside the EU, typically 5–20x cheaper per GB. Example: 5GB in Turkey costs roughly €50+ via per-GB roaming but from about $10 with an eSIM.
Do I lose my phone number with an eSIM?
No. The eSIM provides data alongside your physical SIM — your number stays active for calls and SMS (mind roaming charges for those).
When is roaming the better choice?
Short trips inside the EU/EEA where your home plan already includes roaming, or if your carrier offers a genuinely cheap travel pass for your destination.
