Ovosim eSIM Data Plans for Guernsey

Ovosim does not provide a genuinely unlimited data eSIM for travel to Guernsey. The plans that carry the “Unlimited” label actually contain capped high‑speed data allowances that range from 15GB up to 150GB, depending on the chosen validity period. When the data cap is reached, the speed is typically reduced, although the specific throttled speed is not listed in the available information.

For travelers who require a large amount of data and still prefer predictable costs, Ovosim offers fixed‑data plans such as the 150GB option valid for 31 days or the 90GB and 75GB plans for 30‑day and 15‑day periods respectively. These larger‑cap plans can be more economical for most users, and only if a user expects to use several hundred gigabytes without any throttling would a truly unlimited plan be necessary.

Ovosim does not provide a Guernsey eSIM that includes a phone number or SMS capability. Only data‑only plans are available for Guernsey. Travelers can still use popular VoIP apps such as WhatsApp, Telegram, and iMessage over the data connection to make calls and send messages without a traditional phone number.

Ovosim provides 32 single‑country data packages that include coverage in Guernsey and 20 multi‑country packages that also cover Guernsey. Among the single‑country offerings, data caps range from 1 GB to 150 GB and validity runs from 6 to 31 days, with prices between $5.78 and $137.91. The multi‑country plans share the same data and validity ranges but enable the same data allocation to be used across a set of countries that includes Guernsey, so travelers can switch between those destinations while maintaining their data allowance.
