Cost, coverage, convenience — we compare all three. The short version: roaming loses every time.

| Setup time | Zero (but pay a lot) | ~2 minutes |
| Coverage quality | Depends on carrier deal | Local network speeds |
| Surprise charges | Common | None — prepaid |
| Home number works | Yes | Yes (dual SIM) |
| Works on arrival | Yes | Yes (install before) |

| Multiple countries | Per-country fees | Multi-country plans available |
The cost problem with roaming
Most US and European carriers charge $10–$15 per day for international data — and that daily rate often applies even if you use data for just 5 minutes. On a 10-day trip to Europe, that's $100–$150 in roaming charges before you've done anything special.
Some carriers advertise "free international roaming" at reduced speeds — typically 256 kbps, which is barely enough for text messaging and maps. For anything practical (navigation, photos, video calls), you'll need full speed.
When roaming actually makes sense
Roaming is worth considering in two specific scenarios:
- 1You're traveling for 1–2 days and your carrier offers a daily roaming rate that's cheaper than buying a dedicated plan
- 2You need voice calls on a local number (eSIM provides data only — your home number still works for calls)
For anything longer than 2 days, eSIM is almost always cheaper.
eSIM vs roaming in Europe
European roaming is typically $10/day from US carriers (some offer $5/day plans). For a 2-week European trip through France, Germany, and Spain, you're looking at $70–$140 in roaming charges.
An Orbitelo Europe eSIM covering the same 30+ countries costs around $20–$30 for 30 days of data. That's 80% less for the same connectivity.
eSIM vs roaming in the USA
For international visitors to the US, roaming rates from home carriers are steep — often $8–$15/day. A 7-day visit costs $56–$105 in roaming. An Orbitelo US eSIM with 5–10 GB costs $12–$20 for the same period.
Our verdict
Use eSIM for any trip longer than 2 days. The savings are significant, setup is easy, and coverage is usually better (local network speeds, no throttling).
The only reason to roam: you don't have an eSIM-compatible phone, or your carrier offers a very competitive daily rate for very short trips.
