How we picked

Best eSIM for Europe: questions

What is the best eSIM for Europe?

For most trips, NUM’s 5 GB, valid 30 days plan at $4.79 (shop price on 4 Nov 2026), on 3, A1.net, Proximus. The best one is the plan that covers your days and data on a strong local network. NUM sells eSIMs, so other brands’ prices on this page are linked to their sources.

What is the best eSIM for a week in Europe?

3 GB, valid 15 days for $3.19 on 4 Nov 2026: enough for maps, rides, messages and photos.

What is the best eSIM for 2 weeks in Europe?

5 GB, valid 30 days for $4.79 on 4 Nov 2026, room for social, photos and a few video calls.

Is there an unlimited eSIM for Europe?

Not on 4 Nov 2026. Plans for Europe have a set amount of data, and you can add more to the same eSIM if you run low.

Will it work on my phone?

Dial *#06# on the phone you’re taking. If you see an EID number, it takes an eSIM. Every iPhone from the XR and XS on does, and the SE from 2020, as do Google Pixel 3 and later and Samsung Galaxy S20 and later. The phone must be carrier-unlocked. Not sure? Text PHONE and your model and we’ll check.

Does it come with a phone number?

No. It’s a data-only eSIM. WhatsApp, LINE, iMessage and FaceTime all work over it, and your home number can stay on for calls and codes.
