Amdocs (NASDAQ: DOX) announced that Cielo, one of Brazil's largest payment services providers, has selected Amdocs Remote eSIM Manager to modernize its nationwide payment terminal connectivity platform.

Under the agreement, Cielo will transition from a traditional SIM-based connectivity model to a software-defined model across its fleet of payment terminals deployed throughout Brazil.
