Frequently asked questions
Do I need a credit card to start?
A card is vaulted securely at signup but never charged during the trial — $0 today. The 14-day free trial runs on Nova PBX Pro and Flare SMS Pro (other tiers are direct-purchase), includes 1 phone number, and your card is only charged if you keep the plan after day 14. Cancel anytime before then and you pay nothing.
Can I use both Nova PBX and Flare SMS?
Yes! Nova and Flare are designed to work together — Flare SMS numbers can forward calls to Nova PBX extensions for free, and you manage everything from one Switchboard portal.
Can I switch plans later?
Yes! Upgrade or downgrade anytime from your account settings. Upgrades take effect immediately; downgrades take effect at the start of your next billing cycle.
How do I port my existing phone numbers?
We handle number porting for you. Submit a port request in your dashboard, and we'll coordinate with your current provider. Most ports complete within 3-7 business days.
Can I use my own devices?
Yes. Nova PBX works with any SIP-compatible device, desk phone, softphone, or our web and mobile apps. No proprietary hardware required.
What happens after the trial ends?
If you don't cancel, your paid subscription begins automatically at the plan's regular rate. If you cancel during the trial, you lose access — no charges are ever made without your consent.
