nextSIM does not provide a truly unlimited data eSIM for Belgium. The plans that carry “Unlimited” in their name offer a fixed amount of high‑speed data (1GB per day or 2GB per day) and, after that threshold is reached, the speed is throttled to 512kbps or 2000kbps, depending on the package.
If a traveler needs more data without speed restrictions, nextSIM offers fixed data plans instead. For example, an eSIM Pro Belgium 200GB plan valid for 180 days provides a large amount of high‑speed data without any further limits or throttling, making it a more cost‑effective option for heavy users compared to the capped “unlimited” packages.
nextSIM does not offer Belgium eSIM plans that include a phone number or SMS capability. Only data‑only eSIMs are available for travelers visiting Belgium.
Users who need voice or messaging can rely on popular VoIP applications such as WhatsApp, Telegram, or iMessage, which work over a data connection and allow calls and messages without a traditional phone number.
nextSIM provides 102 single‑country data plans for Belgium and 89 multi‑country plans that include Belgium in their coverage. The plans span a price range from $1.53 to $1, 298.25 and a data cap range from 1 GB up to 200 GB. In addition to the standard fixed data cap offers, 52 of the plans use a daily data cap model, meaning the data allowance is reset every day, whereas the remaining 139 plans apply a fixed data quantity for the full validity period.
