eSimfly eSIM Data Plans for Guernsey

eSimfly does not provide a true unlimited‑data eSIM for Guernsey. The only plan that uses the word “Unlimited” in its name is the O2 Unlimited (International) plan, which contains a 35GB data cap for 30 days; after that cap is reached the connection speed would normally be reduced, although a specific reduced speed is not listed.

Instead, eSimfly offers a range of fixed‑data options that can serve travelers with larger bandwidth needs. For example, an O2 Unlimited (International) plan provides 35GB for 30 days for $35.88 USD, while the Europe Orange 500GB plan delivers 500GB for 90 days for $125.54 USD. Choosing a fixed‑data plan can be more economical unless a user requires constantly high‑speed data beyond the capped amount.

eSimfly provides eSIM plans for Guernsey that include a phone number and SMS capability. The plans allow both inbound and outbound voice calls as well as inbound and outbound SMS messages. The phone numbers are issued with international dialing codes, primarily +33 for French numbers and +44 for UK numbers, rather than local Guernsey numbers.

The available plans range in data allowance from 20GB up to 500GB and in validity from 15 days to 90 days. Prices run from $17.84 USD for a 20GB 31‑day plan to $125.54 USD for a 500GB 90‑day plan. Users who need a specific data amount or duration should confirm the details directly with eSimfly.

For Guernsey eSimfly offers six single‑coverage plans and thirty‑nine multiple‑coverage plans. The available plans span a price range from about $3.08 to $115.60, with data caps that vary between 1 GB and 200 GB, and validity periods that can extend from 5 to 365 days.
