Roambit does not provide a United Kingdom eSIM that includes a phone number or SMS capability. All eSIM plans sold by Roambit for the United Kingdom are data‑only, offering connectivity without local voice or text service. Travelers who need to make calls or send messages can use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection, but the availability of these services can vary by destination, so it is advisable to confirm that the app you rely on works in the United Kingdom before purchasing a Roambit eSIM.
