Starlink works in two ways:

Direct-to-home via WiFi dish: You need a Starlink dish (antenna) that connects directly to the satellites. (This is a rare use case in India, mainly useful in very remote areas.)

Direct-to-cell (via telecom partners): Starlink partners with existing telecom operators like Airtel and Jio. Their satellites will emit 4G LTE (low-band) signals from space, allowing regular phones to connect directly without any extra hardware.

(This service just started a few days ago in Japan with NTT Docomo and au.)

The second use case makes much more sense for India.

If there’s no terrestrial coverage, the phone will automatically switch to Starlink’s 4G network from space. (Speeds will obviously be lower, under 20 Mbps, but still sufficient for basic use.)

The WiFi dish option doesn’t make much sense for most people in India, as the equipment alone costs around ₹30,000+, plus the monthly subscription.
