JoltSMS vs TextNow: verification backbone vs free VoIP texting app

TextNow is a free app that gives you a VoIP phone number to call and text over Wi-Fi or data. It's built for personal communication and low-cost calling. JoltSMS is built for something else: long-term SMS verification with non-VoIP, real-SIM US numbers, a shared inbox, and Team Access so your team can keep critical accounts verified.

Why VoIP-style numbers can be hit-or-miss for verification

Many platforms treat VoIP/virtual numbers differently from carrier-backed mobile numbers. Some restrict them or don't deliver verification codes consistently.

TextNow numbers behave like VoIP numbers, which may work in some cases but are not positioned as a robust verification solution for business-critical accounts.

JoltSMS uses non-VoIP, real-SIM US numbers and is built specifically for long-term account verification and re-verification, which tends to be more reliable than disposable or free VoIP lines.

Neither JoltSMS nor TextNow can guarantee acceptance on every website or service. JoltSMS is optimized for verification workflows and team sharing; TextNow is optimized for free VoIP calling and texting.

Shared verification for teams vs one-person free number

JoltSMS

  • Shared inbox per number
  • Up to 10 team members per number with role-based access:
  • • Owner – billing & number control

  • • Viewer – read-only
  • Codes routed to Slack, Discord, Email, and Webhooks
  • Built for cross-functional teams (DevOps, finance, security, ops, agencies)

TextNow

  • No structured Team Access or shared verification inbox model
  • Great for individuals who want a free or cheap line; not built for team audits or shared verification

When you want a number you keep vs a number you got because it was free

JoltSMS (long-term)

Designed as a long-term, stable number:

  • Keep the same number for AWS, Stripe, banks, marketplaces, etc.
  • Reuse it for re-verification and future security prompts
  • Message history is preserved in the JoltSMS inbox for review and audits
  • Usage is intentional: you rent a specific number because you plan to keep and share it

TextNow (free secondary)

  • You get a number as part of a free/low-cost communication service
  • Great for calls/texts, but not designed as a canonical verification number
  • Being free/VoIP, it's easier to treat it as "nice to have," not a critical piece of infrastructure
  • If access to the TextNow account changes, verification tied to that number can become brittle
