Frequently Asked Questions

Global Messaging Questions Buyers Ask Before Choosing a Provider

Global customer messaging consultation and support illustration

What is the best channel for international verification?

SMS is still the broadest default for OTP. Voice and WhatsApp are useful fallback channels when delivery, urgency or local user preference requires another path.

How can businesses reduce international SMS cost?

Clean phone numbers before sending, route by country and carrier performance, separate OTP from marketing traffic, and monitor cost per successful customer action.

Can WhatsApp replace SMS marketing?

WhatsApp works best for rich, permission-based conversations. Most global teams combine SMS, WhatsApp and email so every journey has the right primary and fallback channel.
