Traffic policyIllustrative scenario, not a specific customer
A global CPaaS platform keeps OTP traffic stable through carrier filtering changes
The platform needed a stable route for verification codes after carrier filtering began blocking shared numbers in one of its markets.
We assigned a dedicated number range, pre-tested each new template against local keyword filters, and moved volume only after a test route to the platform’s own handsets passed.

Do you sell to individual travelers?
No. We sell wholesale to businesses that resell connectivity. For a personal travel eSIM, visit us.cuniq.com (opens in a new tab).
Do you publish prices?
No. Rates depend on destination, sender type and volume, so we quote per request. China circuits are quoted after a route assessment.
Can I test a route before committing?
Yes. Choose “Test route” or “Test eSIM” in the quote form. Test credentials or SIMs can be provided after our team reviews your request.
