MobiMatter does not offer a United Kingdom eSIM that includes a phone number or SMS capability. The available United Kingdom eSIM plans from MobiMatter are data‑only, so travelers cannot make or receive regular phone calls or text messages through the local network.
To communicate while traveling, users can rely on data‑based VoIP applications such as WhatsApp, Telegram, or iMessage. However, some destinations may block or restrict certain apps, so it is advisable to check that the services you rely on are accessible in the United Kingdom before purchasing a MobiMatter eSIM.
