Verify on Telegram first.
Keep other channels ready.
Bumpcube supports Telegram OTP for eligible users who agree to receive verification codes on Telegram. Discuss a Telegram-first verification strategy and your SMS or voice fallback requirements with our team.

Telegram first.
Fallback with purpose.
Start with Telegram for eligible users. Speak to our team about channel order, timeout rules and SMS or voice alternatives for your verification workflow.
Confirm permission
The user shares their phone number and agrees to receive verification messages on Telegram.
Check eligibility
Check Telegram delivery eligibility before attempting the Telegram route.
Attempt Telegram
Send the verification code and monitor delivery and verification within the agreed time window.
Use fallback when needed
If unavailable or timed out, offer or trigger SMS, then voice according to customer rules. Stop when verification succeeds.
Lower delivery cost.
A complete customer journey.
Telegram can reduce costs where users are reachable. Overall savings depend on eligibility, conversion, fallback usage and the agreed Bumpcube price.
For Telegram users, wherever supported
Codes arrive in Telegram over an internet connection. Coverage follows account eligibility and service availability rather than universal mobile-number reach.
Keep the next option clear
Let users request another channel when they cannot access Telegram. Delivery is not the same as successful verification.
One verification attempt, coordinated channels
Set clear requirements for code expiry, retries and alternative channels. Our team can help you assess the right verification workflow for your application.
Know the route.
Is this a Telegram bot?
Our Telegram OTP service delivers phone-number verification codes through Telegram Gateway. It is not a general-purpose bot messaging service.
Is Telegram always the cheapest option?
No. Savings depend on your SMS and voice rates, the share of eligible Telegram users, fallback traffic and provider charges. Bumpcube pricing will be agreed before activation.
Can Telegram replace SMS everywhere?
No. Users must have an eligible Telegram account and opt in to receiving verification messages. SMS and voice remain fallback options.
Can we enable it today?
Bumpcube supports Telegram OTP. Contact our team to confirm your setup, commercial terms and testing requirements before activation.
