Can I expect a signal with CheapESIM on the Arctic Circle Trail or at the Ilulissat Icefjord?

At the Ilulissat Icefjord viewpoint, which is conveniently located near the town of Ilulissat, you will generally have a strong signal with CheapESIM. However, for multi-day treks such as the Arctic Circle Trail (from Kangerlussuaq to Sisimiut), it is critical to assume you will have little to no signal for the entire 160km route. CheapESIM provides excellent connectivity in populated areas, but the vast wilderness of Greenland remains largely uncovered by mobile networks. Plan accordingly for offline navigation and communication in remote zones.
