Simsima does not provide an unlimited data eSIM for Guernsey.
The company offers fixed data plans instead. For example, a 20GB plan valid for 30 days costs $53.03 USD, while a 10GB plan for the same validity is $40.13 USD. A longer‑term option is a 10GB plan valid for 180 days at $80.00 USD. These selected plans illustrate the large‑data choices available, though the full catalogue contains more options. Choosing a fixed‑data plan is typically more cost effective, except for users who need an unlimited data allowance.
Simsima does not currently offer Guernsey eSIM plans with a phone number or SMS capability, so travelers can only access a data‑only eSIM. Users can still use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection for voice and text communication.
Simsima provides four single‑country data plans and nine multi‑country plans for Guernsey. The plans cover a price range of roughly $4.89 to $80.00 and data volumes from 1 GB up to 20 GB, with validity periods between 5 and 180 days.
