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 an eSIM for Ireland that includes a phone number or SMS capability. All plans available from the provider are data‑only, meaning they give you internet access but no local number for voice or text messaging. Travelers can still make calls and send messages through VoIP applications such as WhatsApp, Telegram, or iMessage, which work over the data connection.

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. ByteSIM also provides plans with either a fixed data cap or a daily data cap, with 42 plans of each type available. All plans offer validity periods between 1 and 30 days, and tethering is allowed on most options. No multi-country plans covering Ireland are currently available from this provider.
