Cheapest & Best Portugal eSIMs: Top 9 Providers Compared
We compared nine eSIM providers for Portugal on listed prices, data allowances and validity, from 1 GB to 50 GB, to show which offer fits each trip.
The dated comparison tables below reflect the observation date recorded for each figure and are not a guarantee of current pricing.
How we compared Portugal eSIM prices
We compared nine providers — Airwaily, Airalo, Saily, Nomad, MobiMatter, Ubigi, Jetpac, Yesim and GigSky — on their listed Portugal data plans, reading each allowance alongside its validity rather than price alone. Airwaily publishes this comparison and sells one of the products in it. A 5 GB plan lasting 10 days and one lasting 30 days are different products, so the duration is stated wherever it changes the picture.
Cheapest 1 GB Portugal eSIMs
Airwaily lists 1 GB over 30 days at $0.22, cut from $0.76 in a promotion. Rivals pair the same 1 GB with anything from 3 to 30 days.

Airwaily's 1 GB/30-day plan costs 90.1% less than Yesim's identical 1 GB/30-day offer and 96.9% less than Ubigi's matching package. Against Saily's 1 GB plan, which lasts 7 days rather than 30, the gap is 93.9% — an upfront price difference, not a like-for-like one.
Cheapest 5 GB Portugal eSIMs
Airwaily's 5 GB plan covers 10 days for $1.50. Jetpac asks $3.50 for 5 GB over 30 days, while Airalo charges $6.75 for 5 GB over 7 days.

Airwaily's 5 GB/10-day plan costs 83.3% less upfront than Saily's 5 GB/30-day offer and 77.8% less than Airalo's 5 GB/7-day listing. Both rival plans differ in validity, so only the 5 GB allowance matches.

Cheapest 30 GB Portugal eSIMs
Seven providers list an exact 30 GB plan. Airwaily's 60-day package is $15.58, while Jetpac and MobiMatter both charge $19.99 for their 30 GB offers.

Airwaily's 30 GB/60-day plan costs 71.1% less upfront than Saily's 30 GB/30-day offer and 37.7% less than Yesim's 30 GB/30-day listing. Both rivals expire in half the time, so these are upfront-price differences.
Cheapest 50 GB Portugal eSIMs
Airwaily's 50 GB plan lasts 20 days at $18.46. GigSky's 180-day 50 GB offer is $27.11, and Airalo and Ubigi each list 50 GB over 30 days at $31.50.

Portugal eSIM verdict: which plan fits your trip
Pick by days first. For a short break, Airwaily's 1 GB/30-day plan at $0.22 is the cheapest entry; a fortnight fits the 5 GB/20-day plan at $1.70, and a month the 10 GB/30-day plan at $3.40. If you need a plan that stays usable for months, GigSky's 50 GB/180-day offer at $27.11 and Nomad's 30 GB/365-day listing at $79 are longer alternatives at a higher upfront cost.
Price check: dates, currency and filters
Airwaily retail prices were recorded on 11 November 2026, and competitor records date from 9 November 2026. Amounts appear in USD, and some competitor figures are converted from the provider's own currency rather than quoted in USD at source.

The comparison covers nine selected providers on paid fixed-allowance offers; top up and renewal costs sit outside it, and checkout fees or taxes were not confirmed.
