eSIM Travel Tips for Denmark

Denmark is in the EU but UK networks charge roaming fees

Copenhagen cycling and transport apps
Copenhagen is one of Europe's great cycling cities. The Bycyklen electric bike hire scheme uses an app requiring a data connection. The Rejseplanen transport app covers Copenhagen Metro, S-Tog trains, and buses across Denmark. Download both before leaving your hotel to navigate Copenhagen's excellent public transport.
Legoland Billund and Jutland
Legoland Billund is a popular family destination for British visitors. Billund town and the theme park have good 4G. Jutland motorways and main roads have good coverage. Rural Jutland heathland and some western coastal areas can have weaker signal. Download offline maps before driving into rural Jutland.
Currency in Denmark
Denmark uses the Danish krone (DKK) despite being in the EU. Current exchange rates are roughly £1 to 8.50-8.80 DKK. Denmark is expensive by UK standards, with Copenhagen comparable to London for dining and accommodation. Cash is rarely used , Denmark is almost entirely card-based, but keep your HelloRoam eSIM active for banking apps.

Best time to visit Denmark from the UK

Denmark is wonderful in summer when long days transform Copenhagen and the countryside. Summer (June to August) offers the best weather at 20°C to 26°C with the famous Danish light and long evenings. Copenhagen is at its best from May to September with outdoor cafes and Tivoli Gardens in full swing. Autumn (September to October) is pleasant with foliage and fewer crowds. Winter (November to March) brings cosy hygge season with Christmas markets and Tivoli's winter magic. Spring (April to May) sees Copenhagen come alive again with cycling and harbour bathing.
