The short version

Only OneSignal has a free tier, so it costs nothing to try first.
Each has a real cost: OneSignal free plan email sends cap at 10,000 per month and web push is capped at 10,000 subscribers per send, per onesignal.com/pricing (Aug 2026); Ozonetel no pricing is published in any usable form, so seat rates, per minute charges, number rental and dialler licences are entirely opaque until a sales process is underway, which makes budget approval slow.
Prices and features above were last checked on 31 August 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

OneSignal

Free plan email sends cap at 10,000 per month and web push is capped at 10,000 subscribers per send, per onesignal.com/pricing (Aug 2026)
Professional and Enterprise plans require custom annual contracts with no published rate, per onesignal.com; SMS/RCS messaging and dedicated IPs are gated behind the Professional tier

Ozonetel

No pricing is published in any usable form, so seat rates, per minute charges, number rental and dialler licences are entirely opaque until a sales process is underway, which makes budget approval slow.
Contact centre cost in India is dominated by per minute telecom charges rather than seat licences, so a low quoted seat rate can hide the majority of the bill in usage that scales with call volume.
Feature depth outside voice is thinner than Genesys or Talkdesk, so an organisation prioritising digital-first omnichannel with deep workforce management will find gaps.
The product, support model and integration set are shaped around Indian market requirements, and organisations outside India get a smaller partner network and less mature local support.
On-premise deployment, one of its main selling points for regulated buyers, brings back infrastructure, upgrade and capacity planning costs that the move to cloud contact centres was meant to remove.
