Giga.Tel eSIM Data Plans for Portugal

Giga.Tel does not provide a genuinely unlimited data eSIM for Portugal. All of its plans that contain the word “Unlimited” actually offer 1 GB of high‑speed data per day; after that daily limit is reached the speed is reduced to 512 kbps. Because of the data cap, these plans are not unlimited in the strict sense of continuous high‑speed access.

Fixed data plans are available instead. For example, Giga.Tel’s 50 GB plans—valid for 7 days or 15 days—offere a larger total allowance, though they include a reduced speed of 128 kbps after the 50 GB is exhausted. Choosing a fixed‑data plan can be more cost‑effective, especially for users who need a substantial amount of data but may not require unlimited high‑speed usage.

Giga.Tel does not provide eSIM plans for Portugal that include a phone number or SMS capability. Only data‑only eSIM options are offered.

Because the plans lack a traditional phone number, travelers can still make voice calls and send text messages through VoIP applications such as WhatsApp, Telegram and iMessage, which work over the data connection.

In Portugal, Giga.Tel currently offers 107 multi‑country eSIM data plans, with no plans that are limited to a single country. The available plans span a price range from $4.99 to $195.99 and offer data amounts between 1 GB and 50 GB, with validity periods of 1 to 30 days. Plans come in two main formats: daily‑data‑cap plans, which provide a set amount of data each day, and fixed‑data‑cap plans, which give a designated data bundle for the entire validity period.
