Twilio alternative
for crypto, Web3 and high-risk verticals reaching Vietnamese users
Twilio rejects accounts mentioning crypto, gambling or adult content. NEXO ROUTE delivers OTPs to Vietnamese numbers without KYC, paid in stablecoins, from $0.022 per delivered code.

Why teams move off Twilio
- Account flagged or suspended within 48h of first crypto-related message body
- A2P 10DLC registration required for US numbers — does not apply to VN but the friction blocks onboarding
- Per-SMS price 3-7× higher than ours for the same Vietnamese carriers
- Failed sends still charge your account in many carrier scenarios
- No native crypto billing — chargebacks on cards used to buy SMS credit
What NEXO ROUTE does differently
- Pay in USDT, USDC, BNB, ETH or BTC — no card, no chargebacks, no KYC
- Flat $0.022 per delivered OTP across Viettel / Vinaphone / Vietnamobile (Mobifone $0.027 SMS-only)
- Failed sends never debit your wallet — you only pay for codes the user actually received
- No vertical restriction — crypto, gambling, adult, Web3 all accepted at signup
- Webhook with HMAC signature on every status change
Verticals Twiliorestricts (we don't)
- Crypto exchanges, on/off ramps, wallets
- NFT marketplaces, Web3 dApps
- Online gambling, sportsbooks, lotteries
- Adult content, dating with explicit features
- CBD / cannabis / pharma without licensing
- High-volume accounts without business verification
FAQ
Is the API compatible with Twilio?
No drop-in, but the request shape is similar (POST JSON with phone + code, get back a delivery id). A typical migration is 1-2 hours: swap the base URL, change the auth header, update the response parser. See our Node.js / Python guides.
Can I port my existing Twilio number?
We do not provide owned numbers — we route OTPs over Vietnamese carriers TKC-side. If you specifically need a sender ID you control, contact us on Telegram.
Do you cover the same Vietnamese carriers Twilio does?
Yes, plus Vietnamobile and Gmobile which Twilio routes inconsistently. Voice + SMS routes across all 5 networks.
What happens if your service is down?
We use multiple TKC upstreams with automatic failover. If a route drops, the next picks up. Our 90% delivery target is measured net of failovers.
Do I need a Vietnamese business entity?
No. You sign up with email, top up in crypto, and start sending. No company registration, no tax ID, no proof of business needed.
