Belfius, the first Belgian bank to revolutionize access to its mobile app in collaboration with Firsty
Summer, travel… sometimes to the other side of the world. Belfius is taking an important new step by becoming the first Belgian bank to offer access to its app without roaming charges in more than 160 countries and regions, thanks to eSIM technology in collaboration with Firsty. This innovation allows customers to stay connected to Belfius Mobile and continue managing their finances from anywhere in the world.
The Belfius Mobile app knows no boundaries. Neither do its customers. 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.
