SMS and voice APIs compared: prices and price hikes
APIs that send and receive texts, place and answer phone calls, reach users on WhatsApp and verify phone numbers with one-time codes, from Twilio to leaner carriers like Telnyx and Plivo, compared on what the same US texting, calling and verification volume costs.
Prices at 10,000 US texts a month
Prices are USD per month at each vendor's published US pay-as-you-go rates (or the cheapest plan or credit pack that covers the volume), including phone number rental and per-message carrier fees but excluding one-time sender registration fees, taxes and trial credit. The headline is 10,000 outbound and 1,000 inbound texts from one US local number; we also price 2,000 US call minutes and 1,000 OTP phone verifications.
