Giga.Tel does not provide a Guernsey eSIM with a phone number or SMS capability. Only data‑only plans are offered for travel to Guernsey.
If a phone number or SMS is required, travelers may use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection. However, some destinations may block or restrict these services, so it is advisable to confirm that the apps needed for communication will work in Guernsey before purchasing a plan.
