Migration FAQ
How hard is it to migrate from Plivo?
Most migrations take a few hours. Our REST API follows similar patterns to Plivo's SMS API. We provide migration guides and can help you port your phone numbers.
Is Plivo cheaper for SMS?
Plivo has very competitive SMS rates. However, Zavu offers per-contact pricing which can save you money if you send multiple messages to the same users. Plus, Zavu includes AI agents and Email that Plivo doesn't offer.
What about reliability?
We maintain 99.9% uptime with redundant infrastructure. We use premium carrier connections for SMS delivery. For WhatsApp, we're direct Meta partners.
Can I try before fully migrating?
Yes! Start with a test integration, verify everything works as expected, then migrate your production traffic when you're ready.
Do you offer volume discounts?
Yes, for high-volume senders we offer custom pricing. Contact us for enterprise plan details.
