Zwitchy does not offer any eSIM plans for Denmark that include a phone number or SMS capability; only data-only eSIMs are available from this provider for that country.
Travelers can use popular VoIP applications such as WhatsApp, Telegram, and iMessage over the data connection to make calls and send messages. However, some destinations may block or restrict access to specific apps or VoIP services, so travelers should check that the messaging or calling apps they rely on work in Denmark before purchasing a Zwitchy eSIM.
