Denmark is in the EU but UK networks charge roaming fees

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.
