ByteSIM eSIM Data Plans for Ireland

ByteSIM does not provide a true unlimited data eSIM for Ireland. All plans that carry the “Unlimited” name are actually capped at 1 GB (for the 1‑day plan) or 1 GB per day (for the longer‑term plans), and once the limit is reached the speed is reduced to 10240 kbps. If a traveler needs a larger data allowance, ByteSIM offers fixed data plans, for example a 50 GB plan valid 3–15 days, which give a higher total amount of high‑speed data without the daily cap. These fixed plans can be more economical for users who consume a lot of data.

ByteSIM does not provide eSIM plans that include a local phone number or SMS capability for Ireland. All eSIM offerings for the country are data‑only.

Travelers can still use VoIP applications such as WhatsApp, Telegram, and iMessage over the data connection for calls and messaging, but some destinations may restrict or block certain apps or services. It is advisable to confirm that the required VoIP apps are accessible in Ireland before purchasing a ByteSIM data plan.

ByteSIM currently offers 84 single coverage data plans for Ireland. These plans range in price from approximately $2.90 to $99.90 and include data allowances from 500MB to 50GB.
