Your eSIM picks between these networks on its own. If you see bars and nothing loads, you can pick one by hand.
Your Denmark eSIM runs on 3 and TDC, and your phone picks whichever has the better signal. Other local networks won't carry your data: if you see signal bars and nothing loads, turn off automatic network selection (iPhone: Settings → Cellular → your eSIM → Network Selection; Android: Settings → Network & internet → SIMs → your eSIM) and pick 3 or TDC by hand.
Denmark has three main carriers: TDC NET (historic operator, largest nationwide coverage with 5G), Telia Denmark (part of Nordic Telia group, 5G in major cities), and Telenor Denmark (Norwegian subsidiary, best value). Plugs are Type C and K (Type K is Danish, unique — similar to F but with different grounding pin), 230V — standard European adapters work on C, but K is Danish-proprietary. 4G/5G coverage reaches the entire country including Faroe Islands (administered by Denmark but with separate carriers).
Copenhagen Kastrup Airport (CPH) offers fast unlimited free WiFi. The currency is the Danish krone (DKK, ~6.9 DKK/USD — Denmark has NOT adopted the euro despite EU membership); Danske Bank, Nordea Denmark, and Jyske Bank ATMs accept foreign cards with no commission up to 5000 DKK. Tips are 5-10% (not mandatory — included in prices). Denmark is very expensive — coffee costs 40-50 DKK ($6-7), Joe & The Juice burger 80-100 DKK. MobilePay is the local peer-to-peer payment system (similar to Spanish Bizum). Driving on the right. Bicycles are central — Copenhageners use bikes more than cars.
