Vonage alternative
for developers reaching Vietnamese mobile users at scale
Vonage (formerly Nexmo) gates crypto, adult and gambling accounts behind enterprise sales. NEXO ROUTE accepts those verticals at signup, charges per delivered code, and bills in stablecoins.

Why teams move off Vonage
- Sales review delays for any high-risk vertical (2-6 weeks)
- Per-message price 2-5× higher than ours for VN delivery
- No transparent failed-delivery refund — disputes go through support
- No crypto billing option — friction for Web3-native teams
- Voice OTP coverage on smaller Vietnamese carriers (Vietnamobile, Gmobile) is patchy
What NEXO ROUTE does differently
- Self-serve signup, no sales call, no compliance interview
- Flat $0.022 per delivered OTP — predictable cost vs volume tiers
- Crypto-prepaid wallet credit, automatic top-up via NOWPayments
- Vietnamese-carrier specialist — covers Viettel / Vinaphone / Mobifone / Vietnamobile / Gmobile with consistent SLA
- 5 free test OTPs on signup — verify before committing budget
Verticals Vonagerestricts (we don't)
- Crypto exchanges and wallets (manual review)
- Gambling, lottery, sports betting
- Adult content
- Bulk marketing without explicit opt-in proof
- Accounts without verified business documents for >1k SMS/day
FAQ
How does the price compare for 10k OTPs/month to Vietnam?
Vonage at ~$0.08/SMS = $800. NEXO ROUTE at $0.022/OTP = $220. Both charge per attempted send, but we refund failed sends to your wallet — Vonage does not by default.
Do you support voice OTP like Vonage?
Yes — TKC upstream is voice-first and works with all 5 Vietnamese carriers except Mobifone (SMS-only).
Can I get a dedicated account manager?
For >$5k/month volume, yes — contact us on Telegram. Otherwise the dashboard + docs are designed to be fully self-serve.
Do you offer 2FA libraries like Vonage Verify?
Not a wrapping SDK — we expose the raw send-OTP endpoint and webhook. You generate and verify the code in your own app. See the Node.js / Python guides for a 7-line implementation.
