Cheapest & Best Belgium eSIMs: Top 9 Providers Compared
We compared Belgium eSIM prices from nine providers in USD across ten allowance and validity groups, from 1 GB to 50 GB, to show which listed plan 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 Belgium eSIM prices
We compared nine providers selling prepaid data eSIMs for Belgium — Airwaily, Airalo, Saily, Nomad, MobiMatter, Ubigi, Jetpac, Yesim and GigSky — sorting their listed data plans into ten allowance and validity groups and reading each price next to what it actually buys. A 5 GB plan lasting 7 days and a 5 GB plan lasting 30 days suit different trips, so duration counts as part of the offer. Airwaily publishes this comparison and sells one of the products in it. Every plan covered carries data only; when validity starts depends on the instructions supplied with the plan you choose. The recommendations below follow the recorded prices, not a claim about the whole market.
1 GB Belgium eSIMs by price
Airwaily's 1 GB plan for 30 days costs $0.22 on promotion, down from $0.76, the lowest 1 GB listing. Yesim and Ubigi match the 1 GB/30-day format at $2.23 and $7.20; Jetpac lists nothing at 1 GB.

Airwaily's 1 GB/30-day plan costs 90.1% less than Yesim's 1 GB/30-day plan and 96.9% less than Ubigi's 1 GB/30-day offer. Both comparisons match on allowance and validity, so these are like-for-like upfront price differences on the day we recorded them.
5 GB Belgium eSIMs by price
At 5 GB, Airwaily's 30-day plan leads at $2.63, ahead of GigSky's $6.23 and Saily's $9.89 on identical terms. Jetpac's 5 GB package lasts one day and costs $5.

Airwaily's 5 GB/30-day plan costs 73.4% less than Saily's 5 GB/30-day plan and 57.8% less than GigSky's 5 GB/30-day option. Airalo's 5 GB package covers 7 days at $6.75, so its shorter validity makes it an upfront-price difference rather than a like-for-like one.
10 GB Belgium eSIMs by price
Airwaily's 10 GB/30-day plan at $4.94 is the cheapest 10 GB listing, ahead of GigSky's $9.43 and MobiMatter's multi-country $10.49. Airalo and Ubigi stretch 10 GB over 7 days, while Jetpac's 10 GB option runs 1 day for $7.

Airwaily's 10 GB/30-day plan costs 67.7% less than Saily's 10 GB/30-day plan and 69.1% less than Nomad's 10 GB/30-day offer. Both rivals match Airwaily on allowance and validity, so these are direct upfront-price gaps.
Belgium eSIMs with 15 GB or more
Airwaily's 15 GB/30-day plan heads this minimum-allowance group at $7.03. Most rivals here list 20 GB instead: GigSky's 20 GB runs 90 days for $14.39 and Saily's 20 GB over 30 days costs $23.39, while MobiMatter and Jetpac offer 15 GB.

Airwaily's 15 GB plan costs 69.9% less upfront than Saily's 20 GB/30-day plan and 64.8% less than Nomad's 20 GB/30-day plan. Saily and Nomad include 5 GB more data, so treat these as upfront-price differences across different allowances, not like-for-like comparisons.
30 GB Belgium eSIMs by price
Airwaily, Airalo and GigSky list no exact 30 GB plan for Belgium. MobiMatter's multi-country 30 GB/15-day offer is the cheapest eligible record at $19.99, ahead of Yesim's 30 GB over 30 days at $25.01 and Jetpac's at $25.99.

MobiMatter's 30 GB/15-day plan costs 34.7% less than Ubigi's 30 GB/15-day plan, a like-for-like match, and 63.0% less than Saily's 30 GB offer, which runs 30 days. Nomad lists 30 GB for 365 days at $79, so validity rather than allowance separates that listing from the rest.
50 GB Belgium eSIMs by price
Airwaily's 50 GB/180-day plan is the cheapest 50 GB record at $20.92, ahead of GigSky's matching 50 GB/180 days at $25.11 and Airalo's 50 GB/30 days at $29.25.

Airwaily's 50 GB/180-day plan costs 28.5% less than Airalo's 50 GB offer, which lasts 30 days, and 75.8% less than Saily's 50 GB/90-day plan. The allowance matches but the validity does not, so these are upfront-price gaps rather than like-for-like totals.
Best Belgium eSIM for one week
For a week in Belgium, Airwaily's 1 GB plan at $0.22 is the cheapest option meeting the 7-day minimum, though it runs 30 days. GigSky's 1 GB over 7 days at $2.39 and Saily's at $3.59 fit the week exactly; Airalo's 3 GB/7 days costs $5.40.

Against the week-long options, Airwaily's 1 GB plan costs 90.8% less than GigSky's 1 GB/7-day plan and 93.9% less than Saily's 1 GB/7-day plan. Airwaily's extra 23 days of validity widen the gap, so this is an upfront price comparison rather than an equal-duration match.
Best Belgium eSIM for 2 weeks
Airwaily's 5 GB/30-day plan at $2.63 also leads the 15-day minimum group, followed by GigSky at $6.23 and MobiMatter's multi-country version at $6.49. Airalo's 5 GB package covers exactly 15 days for $7.20.

Airwaily's 5 GB plan costs 79.0% less than Nomad's 5 GB/30-day plan and 73.4% less than Saily's 5 GB/30-day plan. All three match on allowance and validity, so the gap is purely upfront price.
Best Belgium eSIM for one month
This is the cleanest cohort: all nine providers list exactly 10 GB for 30 days, two of them as regional plans, and Airwaily's $4.94 is the lowest, with GigSky at $9.43 and MobiMatter at $10.49.

On identical 10 GB/30-day terms, Airwaily costs 57.8% less than Airalo's $11.70 plan and 67.7% less than Saily's $15.29 plan. Because allowance and validity match across the cohort, no adjustment is needed before comparing the headline prices.
Best Belgium eSIM for two months
For trips of 60 days or more needing at least 30 GB, Airwaily's 50 GB/180-day plan at $20.92 leads. GigSky's 50 GB/180 days at $25.11 is the closest rival, while MobiMatter's 30 GB over 365 days costs $34.99.

Airwaily's 50 GB/180-day plan costs 16.7% less than GigSky's identical 50 GB/180-day offer and 66.3% less than Ubigi's 50 GB/180-day multi-country plan. Both matches align on allowance and validity; Saily's 50 GB lasts 90 days at $86.39, so its 75.8% upfront gap also reflects a different validity.
Which Belgium eSIM should you buy?
Choose by trip length rather than headline price. Airwaily's promotional $0.22 plan suits a short visit with light data use, and its 3 GB/15-day option at $1.51 covers heavier map and photo use. For a full month, Airwaily's 10 GB/30-day plan is 47.6% below GigSky's $9.43 on identical terms, while $20.92 buys 50 GB over 180 days for long stays. Only the 30 GB size goes to a rival, MobiMatter, and its $19.99 plan lasts 15 days.
How we checked these Belgium eSIM prices
Airwaily's Belgium prices were recorded on 11 November 2026 and competitor records on 9 November 2026. Amounts are in USD, and some competitor figures were converted from the currency the retailer published, so a checkout total may differ. Promotional prices are already included rather than added afterwards. Plans were grouped by equal or minimum allowance and validity across nine selected providers, with regional multi-country offers labelled; taxes, fees, eligibility rules and top up costs were not verified.
