Travelers visiting Norway are advised to use eSIM technology and offline GPS maps to ensure reliable connectivity in the country's remote fjords, where major networks like Telenor and Telia may have limited coverage. An eSIM can complement these networks, offering greater flexibility and better coverage in areas with weak signals. Before visiting popular destinations such as Bergen, Trondheim, or the North Cape, it is recommended to compare eSIM providers like Ubigi, Holafly, and GoMoWorld, prepare offline maps, and be aware of areas where signal issues may occur. Ubigi offers customizable data packages with options ranging from 500 MB to 60 GB, or an unlimited plan with reduced speed after 20 GB. It allows users to share the connection (hotspot) on most packages and provides Smartstart activation upon arrival in Norway. However, it does not include a local phone number or SMS, focusing solely on data. Holafly offers unlimited data packages, which are ideal for travelers who prefer not to track their usage. These plans provide full speed up to a daily limit, after which the speed is reduced. Holafly also allows the use of a physical SIM card alongside the eSIM for calls and SMS, though sharing the connection is usually not permitted with unlimited plans. GoMoWorld provides both limited data (4 GB to 75 GB) and unlimited packages, with hotspot and VPN features included by default. It is supported by the Irish operator eir and two local partner networks per country on average, which can be particularly useful in a country like Norway, where coverage varies. However, manual activation may be confusing for some users, and customer support is mainly through tickets with a response time of within 24 hours. Norway is among the best-covered countries in Europe, with 3G and LTE/4G networks reaching about 99.90% of the population. However, remote areas such as enclosed fjords, road tunnels, and mountain ranges can have no signal for several kilometers. Telenor reports average 4G speeds of about 170 Mbps and 5G speeds of around 255 Mbps. Ice, the third major operator, primarily uses its network in large cities like Oslo and Bergen, covering about 80% of the population with its own infrastructure and using a roaming agreement with Telia to extend its reach. For a road trip between Oslo, Bergen, and the Lofoten Islands, connectivity is generally strong on major routes and in cities, but becomes unreliable in enclosed valleys, on certain mountain roads leading to the North Cape, or during a cruise beyond the Arctic Circle. An eSIM with access to multiple partner networks significantly increases the chances of maintaining a stable connection, as the phone automatically switches to the available network. To prepare for a trip, travelers should download offline GPS maps before departure, as no mobile network can guarantee continuous coverage in remote areas. Applications such as Google Maps, MAPS.ME, and Organic Maps offer different features and levels of offline support. For a tour in the Lofoten Islands, around Bergen, or towards Trondheim, it is recommended to download the map of each region before departure, note GPS coordinates of accommodations and meeting points, and keep a paper road map as a backup for the most remote areas. To install an eSIM, travelers should check their phone's eSIM compatibility by dialing *#06#. They should then choose a package based on the length of their stay and data needs, install the eSIM profile before departure using the QR code received by email or via the provider's app, and keep the QR code as a backup. Upon landing in Oslo, they should activate the data package and check the automatic switch to Telenor or Telia. They should also download offline GPS maps as soon as the connection is established before heading to less covered areas.
