eSimfly eSIM Data Plans for Belgium

eSimfly does not provide a true unlimited high‑speed data eSIM for Belgium. All plans marketed with an “Unlimited” name actually impose a fixed daily data allowance; for instance, the Belgium Unlimited 30 Days plan supplies 3GB/day for 30 days at US$25.35. After the daily limit is reached, the network throttles the speed. Another example is the O2 Unlimited (International) plan, which offers 35GB for 30 days at US$27.00.

Because plans labeled “Unlimited” still contain a data cap, users who need genuinely unlimited data should consider fixed‑data options such as the Bouygues Telecom 120GB for 30 days (US$45.50) or similar larger‑allowance plans. For most travelers a fixed‑data plan tends to be more cost‑effective unless extremely high data usage is anticipated.

eSimfly sells several Belgium eSIM plans that come with a dedicated phone number and full SMS support. Prices range from about $22.75 for a 15‑day, 20GB plan up to $45.50 for a 30‑day, 120GB plan, giving travelers a choice of both short‑term and longer‑term validity, and allowing data usage in Belgium as well as coverage in many other countries.

All of these plans provide inbound and outbound voice calls as well as inbound and outbound SMS. The phone numbers are not local Belgian numbers; they come with international dialing codes of +33 (French) for Bouygues Telecom plans and +44 (British) for O2 plans. Users who need specific call or SMS features should confirm the details directly with eSimfly before purchasing.

eSimfly lists a total of 16 single‑country plans and 48 multi‑country plans that cover Belgium. Prices range from $1.20 to $90.60, while data limits extend from 1 GB to 120 GB. The catalogue includes both fixed‑data plans, offering a set amount of data for the full validity period, and daily‑cap plans, which reset each day and give travelers the flexibility to spread usage over short bursts or keep it for longer stays.
