ByteSIM does not provide a United Kingdom eSIM that includes a phone number or SMS capability. The provider offers only data‑only eSIM plans for the United Kingdom, so customers will not receive a local phone number or inbound/outbound SMS service.
Travelers can still communicate while in the United Kingdom by using popular VoIP applications such as WhatsApp, Telegram, or iMessage, which work over the data connection and offer voice and messaging services without requiring a traditional phone number.
