Helium Mobile is a mobile virtual network operator (MVNO) that runs on T‑Mobile’s 5G network and your neighbor-driven Helium Network. Via its app, you can activate your SIM/eSIM, choose free or paid plans, track data, earn “Cloud Points” (or crypto on old plans) by sharing location (“mapping”), manage usage, and pay bills. It’s actual cellular service—not VoIP—and works like any standard mobile carrier.
