While still nascent, this model of building telecom networks has seen promising developments. DePIN networks like Helium have created meaningful supply side footprints, supporting thousands of hotspots. By combining their footprint of hotspots with T-Mobile’s nationwide cellular network, Helium launched Helium Mobile to sell cheap phone plans directly to customers. The experiment is still early, with ~100,000 subscribers and 10,000 suppliers on the network, and many are skeptical it may ever work as free phones and two-year exclusive contracts present meaningful switching costs.
