Zwitchy does not offer any United Kingdom eSIM plans that include a phone number or SMS capability. The provider only sells data‑only eSIMs, so travelers will not receive an outbound or inbound voice line or SMS service on the UK network.
If a phone number or SMS is needed, most users rely on VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection. While these apps generally work on the UK network, some destinations may block or restrict access to specific services, so travelers should confirm that the apps they require are available in the United Kingdom before purchasing a plan.
