Billion Connect provides several unlimited‑data eSIM plans that include Portugal as part of its 33‑country coverage. Prices start at $2.99 USD for a 1‑day plan and rise to $449.65 USD for a 180‑day plan, with intermediate options available for each day up to 90 days. All of these plans state that data is unlimited and that tethering is allowed, but they also note that speed may be throttled.
Because the plans apply a fair‑usage policy, speeds can be reduced after substantial use. Travelers who need to know how much data can be streamed at normal speed should contact Billion Connect directly to confirm the typical amount of data before a throttling event occurs.
Billion Connect does not provide an eSIM for Portugal that includes a phone number or SMS capability. All of its plans for Portugal are data‑only, meaning there is no local or international calling or text messaging service supplied by the eSIM itself. Travelers can still make calls and send messages using data‑based VoIP applications such as WhatsApp, Telegram, and iMessage, which operate over the data connection without requiring a traditional phone number.
Billion Connect provides 190 data plans that can be used in Portugal as part of its multi‑country offering, and there are no single‑country plans available specifically for Portugal. The plans cover a range of pricing from $0.69 to $449.65 and data caps that span from 500 MB up to unlimited amounts. Validity periods vary between 1 and 180 days.
Within the multi‑country portfolio, plans are split into two types: 85 daily data cap plans, which allow a certain amount of data per day before the plan resets, and 105 fixed data cap plans, which provide a set amount of data for the entire validity period. Tethering is permitted on many of these plans, with possible reduced speed limits (128 Mbps) and throttling after the data cap is reached.
