Greenland eSIM

Generally no. Greenland is a self-governing part of the Kingdom of Denmark but sits outside the European Union, so it is not inside the EU roaming rules and is usually its own coverage area. Check the country list on the plan page and look for Greenland by name. If Greenland is not there, do not assume a Europe bundle quietly includes it, because that is the most common way people arrive without a working line.

Plan as if there is none. The route from Kangerlussuaq to Sisimiut takes roughly a week through uninhabited country, and phone service only returns as you close in on the far end. People who walk it carry a satellite messenger for emergencies, leave their walking plan with someone before setting off, and load the maps and GPS tracks onto the phone while still in town with data.

Weather rewrites plans in every season: fog, wind and poor visibility push domestic flights and helicopter legs around routinely. Experienced travellers leave one to two spare days before an international departure and never book a same-day connection onto it. Turn on the airline's notifications and check the status early in the morning, because the decision to fly or not is often taken only a few hours before departure.

With no network to attach to, the phone keeps searching and drains far faster than usual. The common approach is to switch to flight mode while you are out on a fjord or on the trail, then bring the line back up when you re-enter a settlement. Cold makes the battery fall away quicker still, so keep a power bank in an inside pocket where it stays warm and download everything you need before leaving town.

Most plans here start when the phone first connects to a network at the destination, so you can install in advance at home and switch it on after landing. Each plan page states its own rule.

No. The eSIM is a second line, so you keep your home number for SMS OTP. Turn off roaming data on the home line and set the eSIM as the data line.
