Cielo Deploys eSIM Tech to Bolster Payment Terminal Resilience
Event summary
- Cielo is modernizing its connectivity architecture for its nationwide payment terminal fleet.
- The modernization leverages Thales’s eSIM technology to enable remote switching of mobile network operators over the air.
- This implementation is one of the first large-scale deployments of the SGP.32 eSIM specification in Brazil’s POS sector.
- Cielo allocates €4.5 billion per year in Research & Development.
- Thales generated sales of €22.1 billion in 2025.
The big picture
Cielo's move highlights the increasing importance of network resilience for payment processors, especially in regions with potentially unreliable infrastructure. The adoption of eSIM technology, and the SGP.32 standard specifically, represents a shift towards more dynamic and automated network management, reducing operational costs and improving merchant experience. This strategy also positions Cielo to better compete in a market increasingly demanding seamless and secure payment experiences.
What we're watching
- Competitive Response
- Other payment processors in Brazil will likely evaluate similar resilience solutions, potentially accelerating adoption of eSIM technology across the sector.
- Standard Adoption
- The success of this SGP.32 implementation will influence the broader adoption rate of this standard within the Latin American POS market.
- Cost Management
- The long-term cost savings from reduced technician visits and simplified logistics will be a key factor in determining the ROI of this initiative for Cielo.
