ByteSIM does not provide a truly unlimited high‑speed data plan for Portugal. All plans that carry the “Portugal Unlimited Data” name contain a 1 GB per day cap; after the limit is reached the speed is reduced to 10240 kbps. No plan lists the data allowance as unlimited.
Travelers looking for a larger, straightforward data allowance can select one of ByteSIM’s fixed‑data plans. For example, ByteSIM offers a 50 GB package valid for 3, 5, 7, 10, or 15 days, or a 1 GB one‑day plan whose speed drops after the cap is reached. These fixed plans may be more cost‑effective unless a user truly needs unlimited high‑speed data.
ByteSIM does not provide an eSIM for Portugal that includes a phone number or SMS capability. The provider only offers data‑only plans for the country, so travelers will not have a local calling code and cannot receive or send regular SMS messages. However, they can still use internet‑based messaging and calling services such as WhatsApp, Telegram, and iMessage over the data connection.
ByteSIM currently offers 84 single coverage data plans for Portugal. These plans range in price from approximately $2.90 to $99.90 and provide data allowances between 500MB and 50GB.
