Verification reliability: non-VoIP vs disposable VoIP numbers
Many platforms treat VoIP/virtual numbers differently from carrier-backed mobile numbers, and some either reject or silently fail verification to them.
Services like Burner are explicit that they "don't always work for every site and every SMS verification code attempt".
JoltSMS focuses specifically on non-VoIP, real-SIM numbers used over time, which tend to be more reliable for verification and re-verification than throwaway VoIP lines.
JoltSMS cannot guarantee acceptance on any specific site, but it's designed around the types of numbers that platforms are more likely to accept for verification.
Shared verification for teams vs one-person numbers
JoltSMS
- •Shared inbox for each number
- •Up to 10 users per number with Owner/Manager/Viewer roles
- •Slack/Discord/Email/Webhook notifications to on-call, finance, or ops channels
- •Clear ownership: numbers and history belong to the organization
Burner
- •Mobile app centered on one user/account with private numbers
- •No roles or multi-user access for the same number in a structured way
- •Great for an individual's privacy, not for cross-team verification workflows
When you want to keep a number vs burn it
Long-term (JoltSMS)
Use the same number for:
- •AWS/GCP root/admin accounts
- •Stripe/PayPal/fintech accounts
- •Banks and treasury
- •Shared SaaS logins and SSO fallbacks
- •Re-verification months later still goes to the same number.
- •Message history is preserved in the JoltSMS inbox.
Burn-and-replace (Burner)
Numbers are intended to be temporary and disposable—you can "burn" them at any time and create new ones.
Great for short-lived use cases like:
- •Marketplace listings, dating, and classifieds.
- •Not ideal when you need the same number to work years later for compliance checks or KYC updates.
