Checking balances, making transfers, activating payment cards for use abroad, quickly adjusting spending limits, placing buy or sell orders, or monitoring the evolution of your portfolio via Re=Bel. From now on, everything is possible. Anytime, anywhere, worldwide. Without extra roaming charges. There is no longer any need to replace a physical SIM card or upgrade your mobile subscription. From now on, Belfius Mobile users have access to all the features of their app in more than 160 countries and regions worldwide, without any additional roaming charges, thanks to eSIM technology in partnership with Firsty.

Smart connectivity, anywhere in the world

Belfius customers can download the Firsty app through Belfius Mobile. They then create a Firsty account by verifying their phone number. By activating the eSIM once for free via Firsty, Belfius customers can use Belfius Mobile anywhere in the world without incurring additional roaming charges. This gives Belfius customers added convenience and peace of mind, almost anywhere in the world. Available starting from the latest version of Belfius Mobile (updated on June 23, 2025).

An eSIM (embedded SIM) is the digital successor to the traditional physical SIM card. This technology is now integrated by default into almost all recent smartphones, tablets, and smartwatches. With an eSIM, users can easily connect to mobile internet without needing a physical SIM card.
