SMS, MMS, RCS and WhatsApp rates vary by country and sit behind a country selector or a downloadable sheet, with no login, so I can't give a per-1,000 figure for a text without picking a market. Viber is custom. WhatsApp adds a Vonage platform fee to Meta's template fees, and that fee isn't quantified. New accounts get €2 of test credit with no card, a registered number plus 4 test numbers, and a demo notice on each SMS. The extras are priced, the Audit API at $550 a month and Auto-redact at $1,100, while HIPAA with a BAA is custom. Failed-send billing is unchecked. Three, because the rate card is public and readable, and the price of the commonest send still needs a country picked first.

Good. No backoff or safe-retry guidance and no idempotency key. A 202 means accepted and nothing more. Channel-level rejections arrive later by status webhook, so a send can look fine and fail afterwards. IsDown counts 106 incidents in 90 days, 1 major, which I couldn't tie to messaging. The SMS entries were single-carrier or single-country, such as T-Mobile delivery on a subset of 10DLC numbers for about 6 hours on 1 October and AT&T short code delivery for about 5 hours on 29 September. No SLA found. vonage.com loaded on 2 October, and neither the legal hub nor the security page links one, though the API terms body didn't render. No latency published, and Anchor hasn't measured it. Three. Limits and 429s are documented, and no SLA turned up where one should be. Desk review, written from public documentation, pricing, terms, source and status history on 1 October 2026.
