JoltSMS FAQ
Short answers to the questions we get most about JoltSMS numbers, verification, delivery, billing, and team access. For deeper walkthroughs, each answer links to a full guide.
About JoltSMS & Our Numbers
What's the difference between JoltSMS and free "receive SMS" sites?
Free "receive SMS" sites use shared, disposable numbers that are often abused and blocked by major platforms. JoltSMS gives you a dedicated, real-SIM US number you rent month-to-month, so it stays tied to your accounts for login and re-verification—and only your team sees the codes.
Learn moreAre JoltSMS numbers VoIP?
No. JoltSMS numbers are real-SIM, non-VoIP US numbers running on carrier hardware, not internet phone lines. That's why they work in more verification flows than VoIP or burner numbers.
Learn moreWhat does "long-term temporary number" mean?
You rent each number month-to-month instead of for just a few minutes. That gives you the flexibility of a temporary number and the stability to pass re-verification checks months later, as long as you keep your subscription active.
Which countries do you support?
Today, JoltSMS provides US-based numbers only. Many international platforms accept US numbers for verification, but always check the service's rules for your region.
Learn moreNumbers, Verification, and Re-Verification
How long can I keep my JoltSMS number?
As long as your subscription stays active. Numbers are billed monthly and auto-renew, so you can keep the same number across re-verification checks and account changes. If you cancel, the number will eventually be recycled and should no longer be used for login.
Learn moreCan I reuse the same number for re-verification?
Yes—that's the whole point. Unlike disposable numbers, your JoltSMS number is meant to stay with your account so you can pass re-verification months later, as long as you keep renting it.
Why can't I use this number for verification?
Some platforms block numbers for reasons outside our control—previous account abuse, device or IP reputation, or region rules. When you see "this number cannot be used for verification," try again later or contact support with the error details so we can investigate.
Learn moreDoes JoltSMS work with every website or app?
No service can guarantee universal acceptance. JoltSMS works with many major platforms, especially where VoIP numbers fail, but each provider has its own risk rules. Check our Platforms guides for the services we see the best results with.
Learn moreMissing, Delayed, or Rejected Codes
Why is my code missing or delayed?
Most codes arrive within a few seconds, but delays can happen due to carrier congestion, platform throttling, or local routing issues. Refresh your Jolt inbox, confirm the right number is selected, and retry the code request once. If nothing arrives, follow the full troubleshooting checklist.
Learn moreDo you guarantee delivery of every verification SMS?
No provider can guarantee 100% delivery, because the sending platform and carriers control part of the path. We operate carrier-grade SIM hardware and actively monitor delivery, but some messages may still be blocked or dropped. If you suspect a delivery issue, open a support ticket with timestamps and sender details.
Learn moreCan I use my Jolt number for outbound SMS or voice calls?
JoltSMS is designed for receiving verification and 2FA codes, not for bulk SMS marketing or voice calls. Outbound usage or calling may be blocked or treated as a violation of our Acceptable Use Policy.
Learn moreBilling, Renewals, and Refunds
How much does JoltSMS cost and how am I billed?
JoltSMS is billed as a flat monthly subscription per active number (no per-code fees). Your plan auto-renews each month until you cancel. You can manage billing details from your account and see current pricing on our site.
Learn moreCan I pause or cancel my number?
You can cancel at any time from your account settings; your number will remain active until the end of the current billing period. Because numbers are allocated specifically for your account, we can't guarantee you'll get the same number back if you re-subscribe later.
Learn moreDo you offer refunds?
We aim to be fair when something truly goes wrong. Our refund policy explains when we can and can't issue refunds—for example, in cases of persistent delivery failure on our side.
Learn moreTeams, Security, and Privacy
Can my team share access to codes?
Yes. JoltSMS is built for teams: you can invite teammates to your account, and they'll see the same verification inbox. You can also route codes into shared Slack channels or Discord servers for faster "what's the code?" responses.
Learn moreHow do you protect my data and OTPs?
We store only the data we need to operate your number and deliver codes to your team. Access to SMS content is restricted to authorized users on your account, and you can control who has access via team management. For more details, see our Privacy Policy.
Learn moreCan I forward codes to Slack, Discord, email, or webhooks?
Yes. JoltSMS can post new codes into Slack or Discord, send them via email, and deliver them to your own systems via webhooks. You configure these destinations from your account settings.
