Helium Mobile: T-Mobile Roaming from a Crypto Network

Helium is DePIN's flagship success story. Users deploy 5G hotspots at home; the hotspot provides coverage; Helium pays them in HNT tokens. In 2023 Helium Mobile launched as a T-Mobile roaming service that also uses Helium's own network wherever it exists.

How the network works

1. User buys a Helium 5G hotspot (~$300-800 depending on model).
2. Sets it up at home with power + internet.
3. Hotspot broadcasts small-coverage 5G.
4. When phones connect, hotspot verifies it and earns rewards.
5. User earns MOBILE tokens for coverage + data.

Helium Mobile the phone plan

• $20/month unlimited data.
• Users' phones use Helium hotspots wherever available (offloading traffic).
• T-Mobile roaming for coverage gaps.
• Users on Helium Mobile earn MOBILE tokens for their coverage contribution.

Real numbers

• 1M+ hotspots deployed globally.
• Hundreds of thousands of Helium Mobile subscribers in the US.
• Actual T-Mobile roaming deal signed 2023.
• Meaningful token emissions to hotspot operators.

Why this proved DePIN

Pre-Helium: telecom infra required $B in capital and government spectrum bidding. Helium showed that a token-incentivized network could deploy comparable coverage in dense areas at a fraction of the capex. T-Mobile's willingness to sign the roaming deal validated the model.

Limitations

• Coverage is dense in cities, spotty outside.
• Hotspot ROI depends on local phone traffic (many operators underearn).
• Token emissions may not sustain long-term if usage doesn't grow.
