ZenSim eSIM Data Plans for Guernsey

ZenSim does not provide a true unlimited high‑speed data plan for Guernsey. All ZenSim plans for Guernsey have a defined data cap, for example 3 GB per day or fixed amounts such as 20 GB or 40 GB for 30 days. When a plan is labeled “Unlimited, ” it actually offers a 3 GB/day allowance and the speed would be reduced once that limit is reached. Travelers who need larger data allocations can choose higher‑top‑up options such as the 40 GB 30‑day plan at $51.00 USD or the 20 GB 30‑day plan at $29.00 USD, which are fixed‑data plans that can be more cost‑effective than a true unlimited plan.

ZenSim does not provide Guernsey eSIM plans that include a phone number or SMS capability. The provider offers only data‑only eSIM plans for Guernsey. Travelers who need voice or text services can use popular VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection to make calls and send messages.

ZenSim offers 12 single‑country plans for Guernsey and 13 multi‑country plans that include the island. Prices range from $6.00 to $115.00, with data caps spanning 1 GB to 40 GB and validity periods between 5 and 30 days. Among the plans, 6 feature daily data caps while 19 provide a fixed data amount, giving customers the option to choose between a per‑day limit for tighter control or a total data allotment that applies for the entire validity period. Some plans also allow tethering, offering additional flexibility for travelers.
