Communication is a vital part of travelling in Greenland. However, mobile phone communication in Greenland, especially out in the remote nature, is very different from what you might expect at home. Mobile phone coverage is generally limited to the areas around the settlements and in general does not cover areas even a short distance away from settlements in the local backcountry or fjords. Furthermore, many foreign sim cards and providers do not cover or work in Greenland and if they do they can be extortionately expensive. If you are in Greenland for a holiday it can be advisable to obtain a local prepaid sim card from Greenland’s telecommunication company TUSASS. Whilst this doesn’t help with the lack of coverage at least you will be able to call in cases of emergency around the settlements.
If you intend to spend lots of your time in more remote backcountry areas it is vital that you have other forms of communication with you. For example satellite communication devices such as a Garmin InReach. Whilst these are useful it is best that you are familiar with your devices functionality before you travel and have tested it. Due to the large latitudinal extent of Greenland, you need to make sure your device operates at the latitudes you expect to visit. In all cases satellite devices require a subscription much like a mobile phone, so it is necessary that this is activated and tested before you head out into the backcountry. In some countries such as Iceland, it is possible to rent satellite communication devices however, this is not the case in Greenland.
Finally, it is important that you communicate any travel itineraries outside of settlements (i.e in areas without mobile phone coverage) with someone you trust. This includes even short day trips. Provide them with your travel plan and when you intend to arrive back. If possible provide as much information about your trip and any alternative plans if situations change so that the person has as much information as possible. It is important that you agree that you inform the person as soon as you arrive at your destination, or try to let them know of any delays so that no unnecessary search party is initiated.
