The most useful quote:

The Direct to Cell network will expand Starlink’s vision by providing
ubiquitous connectivity and seamless access to text, voice, and data for
LTE phones and devices across the globe.  Text service begins this year,
followed by voice, data, and Internet of Things (IoT) services in 2025.

Developing a satellite network that connects to unmodified cell phones
presents several new technical and regulatory challenges beyond those
Starlink has already overcome...

...

The Direct to Cell network leverages the infrastructure we’ve built
for Starlink over the past several years. Direct to Cell satellites plug
into the existing Starlink satellite constellation via laser backhaul;
meaning even our early satellites can provide services anywhere with
regulatory approvals without requiring dedicated ground infrastructure.
We also leverage all the existing networking, ground stations, and Points
of Presence (PoPs) Starlink has developed. The Direct to Cell data travels
over Starlink’s core directly to the operator’s core, providing a
seamless integration.  

In August 2022, we announced our first partnership with T-Mobile, and
have since announced deals with Rogers in Canada, Optus in Australia,
One New Zealand, KDDI in Japan, Salt in Switzerland, and Entel in Chile
& Peru. The operators provide critical LTE spectrum in the 1.6- 2.7 GHz
range that we use to transmit our satellite signals.
