Can I expect mobile signal while hiking the Arctic Circle Trail or visiting the Ilulissat Icefjord?

At the Ilulissat Icefjord viewpoint, which is conveniently located near the town, you'll generally find a strong signal. However, for multi-day expeditions like the Arctic Circle Trail (spanning from Kangerlussuaq to Sisimiut), it's crucial to prepare for extended periods with no signal whatsoever across the entire 160km route. eSIMFlyer provides excellent coverage where available, but always carry satellite communication for true wilderness treks.
