ChillaxSIM eSIM Data Plans for Guernsey

ChillaxSIM does not provide a true unlimited data eSIM for Guernsey. All of its plans listed for the island offer a fixed data allowance; the names that contain “Unlimited” actually provide 1GB of high‑speed data per day, and once that limit is reached the speed drops to 5, 000 kbps.
As alternatives, ChillaxSIM sells larger fixed‑data plans such as the 20 GB for 30 days plan priced at $33.90 USD and the 10 GB for 15 days plan at $19.90 USD. These plans give you a set amount of data without throttling, which can be more cost‑effective for travelers who need a reliable data supply but are not extremely heavy users.

ChillaxSIM provides eSIM plans for Guernsey that include a phone number and SMS functionality. The available plans use the +33 dialing code, which is not a local Guernsey number but rather a French one. Calls can be received and made (inbound and outbound voice) and SMS can be sent and received (inbound and outbound). Prices range from $21.90 USD for 20GB to $47.90 USD for 100GB, and each plan is valid for 30 days. The plans cover Guernsey and 40 additional countries in Europe. Users should confirm the specific features directly with ChillaxSIM before purchasing.

ChillaxSIM provides 39 single‑country data plans and 4 multi‑country plans for travelers in Guernsey.
The available plans cover a data range from 500 MB up to 100 GB and a price range from $2.50 to $98.90.
Within these options, some plans feature a fixed data cap while others employ a daily data cap, giving customers flexibility depending on their usage patterns.
