Is eSIMFlyer data necessary for dog sledding tours in Greenland, especially for coordination?

While deep wilderness areas, particularly around remote spots near Tasiilaq, will likely be off-grid, having your eSIMFlyer data active at the trailhead or departure point is absolutely vital. This ensures seamless coordination with your dog sledding guides, allows you to confirm last-minute details, and provides a crucial safety net before venturing into areas with no signal. It's about preparedness before immersion.
