Which carrier does Helium Mobile use?

Could you clarify which aspect of Helium Mobile you're specifically referring to when asking about their carrier? Helium Mobile, as a concept within the realm of cryptocurrency and blockchain technology, typically relates to a decentralized network that enables devices to communicate directly with each other, bypassing traditional cellular carriers. However, if you're inquiring about a specific mobile service or device utilizing the Helium network in a consumer-facing capacity and their reliance on a traditional telecommunications carrier for some aspect of their service, it's worth noting that the Helium Network itself is designed to be carrier-agnostic, facilitating peer-to-peer communication between devices. In short, the question "Which carrier does Helium Mobile use?" might be misdirected if it's assuming Helium Mobile operates as a traditional mobile service provider reliant on a single carrier. Could you elaborate on your query or provide more context to ensure an accurate response?
