An infrastructure of innovation

Apple-designed components and software allow iPhone 14 antennas to connect to satellite frequencies. And since bandwidth is low, we created a compression algorithm that makes text messages three times smaller, speeding up communication.

On the ground, we route your text message through a complex infrastructure to emergency service providers. Only some accept texts. For those that don’t, we’ve set up emergency relay centers with Apple‑trained specialists who call for help on your behalf.
