Best eSIMs for a month-long trip

Sizing data for 30 days

Over a month, small daily habits add up. A light month (maps, messaging, browsing) runs 8–15GB; a moderate month with social and some streaming lands around 20–35GB; a heavy month of daily video calls, streaming and hotspotting can pass 50GB. Because bulk data is much cheaper per gigabyte, a single large 30-day bundle almost always beats stacking several short plans — and you avoid re-purchasing on the road.

One country or a whole region

Basing yourself in one country for the month? A local plan is usually cheapest. Doing a regional loop — Southeast Asia, the Balkans, Latin America? A regional plan covers the whole route on one 30-day install, which is far simpler than a new eSIM per border. The trip stacker runs both options with live prices so you can see the real difference for your route.

Month-long details that matter

The validity start point matters most on a long plan — a purchase-start plan quietly burns days if you buy early, so favor first-use activation or buy close to departure. Check for top-ups in case you underestimate, keep the profile installed the whole time, and note the expiry date somewhere you will see it. Install on home Wi-Fi before you go.
