Indian temporary numbers on InstantSMS use the +91 country code followed by a 10-digit mobile (for example +919876543210). India does not use a domestic leading 0 in the same way as many EU countries - enter the full +91 number as shown, or select India in the country dropdown and paste the 10 national digits. Public Indian lines see heavy OTP traffic, so pick a number with recent inbox activity and expect some services to reject shared ranges. Never use a public inbox for banking, UPI, or anything tied to permanent identity.
