Can I register these numbers with WhatsApp, Facebook, Gmail?
Possibly, but not guaranteed. Acceptance is fully determined by the external service (WhatsApp, Facebook, etc.) and not by IsraelNumber.
Why might my number not be accepted by WhatsApp?
WhatsApp and similar services often block VoIP ranges or certain international prefixes due to internal anti-fraud policies, even if the number is valid.
Do you offer refunds if a number is rejected by WhatsApp?
No. Since third-party services control their own verification policies, acceptance cannot be guaranteed and refunds are not provided for this reason.
6. Billing & account management
How does billing work and how do I cancel a service?
