OneSky

One eSIM for the whole planet — towers, satellite-to-phone, and a pocket Puck for everywhere else.

See what a OneSky traveler gets there: roaming towers, direct-to-cell satellite straight to an iPhone, or Puck satellite messaging.

Installs on iPhone XS and later with iOS 17.4+ in one tap (Apple's eSIM setup link). Satellite-to-phone needs iPhone 12 or later and a partner network overhead.

Traveler's iPhone ⇄ Puck (BLE)

This phone talks to the virtual Puck firmware over its BLE GATT channel. The Puck sends over (simulated) satellite to the gateway.

Queued at the gateway; rides down on the Puck's next satellite window (NTN devices can't be paged).
