AloSIM does not offer a Guernsey eSIM that includes a phone number or SMS services. Only data‑only plans are available for this destination.
Travelers who need to send messages or make calls can rely on internet‑based apps such as WhatsApp, Telegram or iMessage over the data connection. However, some destinations block or restrict access to specific VoIP services, so it is advisable to confirm that the apps you rely on are available in Guernsey before purchasing a data‑only plan.
