SMSGatewayHub invoices clearly split base amount and GST component — suitable for GST input credit claims by registered businesses.

Twilio bills in USD — India SMS costs approximately $0.005–$0.007 per message which at current USD/INR (≈84) equals ₹0.42–₹0.59/SMS. Add 18% GST on top. That's 3–5x more expensive than Indian providers like SMSGatewayHub. Twilio also doesn't have native TRAI DLT compliance support — requiring significant manual setup for Indian businesses, adding further hidden cost.
