ASIMGO does not offer any eSIM plans for Guernsey that include a phone number or SMS capability. The available Guernsey eSIMs are data‑only, so users cannot make or receive standard voice calls or SMS messages while the plan is active.
If a phone number or text messaging is required, travelers can use family‑friendly VoIP services such as WhatsApp, Telegram or iMessage over the data connection. These apps generally work in Guernsey, but some destinations restrict or block particular services, so it is advisable to confirm that the VoIP apps you rely on are accessible before purchasing a data‑only plan.
