Zwitchy does not provide eSIM plans that include a phone number or SMS ability for the Netherlands. Travelers who need this feature will need to look elsewhere or use dedicated VoIP applications such as WhatsApp, Telegram or iMessage over the data connection.
Only data‑only eSIM plans are offered, so if you rely on traditional voice calls or text messaging you should verify whether the VoIP apps you plan to use are accessible in the Netherlands before purchasing a Zwitchy plan.
