TL;DR
VirtualSMS provides Signal verification via real Bulgaria mobile numbers (+359 prefix) — physical carrier-issued SIM cards, not VoIP. Bulgaria numbers from regional operators pass Signal's network-detection checks where Google Voice, TextNow, and MySudo get rejected as disposable. Numbers activate in under 30 seconds. Pricing from $0.40 per activation, paid in USDT, USDC, BTC, LTC, or SOL via NOWPayments. If the Signal code doesn't arrive within 20 minutes, your balance is refunded automatically. Alternative to hero-sms, 5sim, SMSPool, SMS-Man, OnlineSim for Bulgaria Signal verification — with real SIMs instead of shared VoIP pools.

Full Privacy
Pay with crypto. No personal info required. Your real number stays private.
Which Bulgaria carriers we run
Bulgaria Signal activations come from a mix of tier-1 mobile networks and the MVNOs that diaspora communities lean on for cheap international rates. The pool rotates with stock — right now you're likely to get a SIM from A1 Bulgaria, Yettel Bulgaria or one of the MVNO brands that ride those same networks: Vivacom. All real mobile-network SIMs, not VoIP. Signal's anti-VoIP detection (the same check that rejects Google Voice and Twilio numbers) sees these as regular Bulgaria mobile lines because that's what they are.
Five real reasons privacy-focused users verify Signal without their personal number
None of these are sketchy. They're the reasons we hear from customers who specifically chose Signal for privacy — and then discovered the registration paradox.
01
Signal uses your phone number as your permanent account identity
Unlike Telegram's username system or WhatsApp's contact-list approach, Signal ties your account completely to your phone number. Every contact who saves your number can find you on Signal automatically. A virtual number lets you use Signal's end-to-end encryption without revealing your real SIM to everyone you've ever exchanged numbers with.
02
A second Signal account requires a second phone number — full stop
Signal allows exactly one account per phone number, globally and permanently. If you want a personal Signal AND a work/community/project Signal, you need two numbers. A virtual number avoids carrying a second physical SIM or paying for a second mobile plan — you get the second account, not the second phone bill.
03
VoIP numbers fail Signal's verification — consistently
Signal specifically blocks Google Voice, TextNow, TextFree, Twilio, and similar VoIP ranges. If you've tried a free online SMS service and gotten 'This phone number is not allowed to register', it's because Signal checks against carrier-type databases. Real SIM cards from real carriers are the only reliable path through.
04
Signal account recovery depends entirely on access to the original number
If you lose access to your Signal account (new device, app reinstall, PIN forgotten), Signal re-verifies via the original phone number. If that number was your personal SIM and you've since changed carrier or country, you're locked out. A dedicated rental number gives you that recovery number reliably — for as long as you hold the rental.
05
Data-only SIMs and eSIMs can't receive Signal's SMS codes
Signal's registration flow sends a 6-digit SMS code. If your primary device runs on a data-only eSIM, a travel SIM, or a business mobile plan that skips SMS — Signal's code simply never arrives. A virtual number with real inbound SMS solves this in under 30 seconds.
Signal-specific problems and how to fix them
Signal's failure modes are different from WhatsApp and Telegram. These are the actual issues we see — each has a specific fix.
"This phone number is not allowed to register" or "Invalid phone number"
Why it happens
Signal has flagged this number's carrier range as VoIP or as a previously abused range. This fires before Signal even attempts to send an SMS — it's a blocklist check, not a delivery failure. Shared inbox numbers (free services) hit this almost universally.
The fix
Cancel the current number on VirtualSMS for a full refund. Get a number from a different country — UK, Poland, and Czech Republic have the cleanest Signal carrier reputation in our fleet. If you've been trying VoIP services or free shared inboxes, this is exactly why they fail: Signal maintains its own carrier-type database.
"Too many attempts — try again later"
Why it happens
Signal rate-limits registration attempts per phone number AND per device. If you tried 3+ times on the same number or hit Resend repeatedly, Signal locks that number (and sometimes the device) for up to 24 hours.
The fix
Cancel the current number on VirtualSMS for a full refund. Wait 15+ minutes before trying a new number from a different country. Do not keep tapping Resend — each attempt deepens the lockout. If the device itself is flagged, try Signal registration on a different device or after clearing the app data.
Code never arrives within 2 minutes
Why it happens
Either Signal's SMS gateway has a temporary routing issue to that specific carrier, or the number's range is quietly deprioritized on Signal's SMS delivery queue without hitting an outright block. Not related to your account.
The fix
Cancel for a full refund. Try a different country — UK, Poland, and Ukraine currently have the fastest Signal SMS delivery in our fleet. Don't hit Resend more than once; after two Resend requests, Signal may start routing to voice call instead of SMS, which is slower.
Signal offers a voice call instead of SMS — and no voice call comes
Why it happens
Signal's fallback to voice call fires when the SMS route is congested or the number range triggers their secondary-check flow. Not every VirtualSMS number receives inbound voice calls — it depends on the country and carrier.
The fix
Check your VirtualSMS dashboard — if the number supports voice, the call transcript appears there. If not, cancel for a full refund and try a different country. UK, Germany, and Netherlands numbers in our fleet reliably receive voice calls for Signal's voice-OTP fallback.
Code arrives but Signal says it's wrong
Why it happens
The code expired (Signal codes are valid for ~10 minutes), or you requested a resend and typed an older code — Signal invalidates all previous codes when a new one is sent.
The fix
Always use the MOST RECENT code in your VirtualSMS inbox. If you see multiple Signal codes in your dashboard, ignore all but the newest. If the newest also fails, cancel for a refund and restart with a fresh number.
Signal account locked after registration — asks to re-verify with the original number
Why it happens
Signal's PIN system requires re-verification via the original phone number if too many wrong PIN attempts are made, or if Signal suspects the account was taken over. This is Signal's security design — the number IS the account identity.
The fix
This is why renting rather than activating matters for Signal accounts you plan to keep. If you used a pay-per-activation number (now released), you can't re-verify. Contact VirtualSMS support within 24 hours — in some cases the number can be returned for a re-verification window. For future Signal accounts you intend to use long-term, rent the number.
Signal says the number is already registered
Why it happens
A previous holder of this SIM registered it on Signal, and that account still exists. Signal's account-to-number binding persists even if the previous user no longer uses the app — there's no automatic expiry.
The fix
Cancel the current number for a full refund. Grab a fresh number from a different country. When Signal registration lands on a number with a prior account, Signal sends the code to the previous account's linked devices first — so even if the code eventually arrives in your inbox, the previous account holder can intercept it.

Frequently asked questions about Signal virtual numbers
Does Signal detect and block virtual numbers?
Signal specifically blocks VoIP numbers (Google Voice, TextNow, TextFree, Twilio) and shared-inbox ranges. What it does NOT block is real carrier-issued SIM numbers — which is what VirtualSMS provides. The check is carrier-type based, not 'virtual vs real'. A fresh SIM from EE, Orange, or T-Mobile passes Signal's check identically to any other user's phone.
Can I use a virtual number for a second Signal account?
Yes — this is one of the most common reasons people come to us. Signal allows exactly one account per phone number. A second account requires a second number. Once verified, you can run both Signal accounts on the same phone using Signal's linked devices or a dual-SIM setup for the second account.
What happens if I forget my Signal PIN later?
Signal gives you a 7-day grace period to remember your PIN before locking the account. After that, recovery requires SMS re-verification to the original registered number. If you used a pay-per-activation number (single-use), that number has been released and can't receive the re-verification code. For Signal accounts you'll use long-term, rent the number specifically because of this.
Can I transfer my Signal account to a new phone number later?
Yes — Signal has a 'Change number' feature under Settings → Account → Change Number. You'd need a new virtual number for the new registration. Your message history, contacts, and groups stay with the account through the change. You don't need to re-verify all your contacts.
Will Signal see my real IP address even with a virtual number?
VirtualSMS provides the phone number for SMS verification only — it doesn't route your Signal traffic. Signal itself is end-to-end encrypted and its servers see your IP during registration. If IP anonymity is part of your threat model, combine the virtual number with Signal's built-in sealed sender feature and a trusted VPN or Tor — those are Signal-layer controls, separate from the number.
How long does Signal verification take end to end?
Under 3 minutes typically. Signup → buy number → SMS arrives (usually 15–30 seconds for Tier 1 countries) → enter code → set PIN → done. If SMS hasn't arrived after 2 minutes, cancel for a full refund and try a different country — don't keep retrying on the same number.
What's the cheapest country for a Signal number?
Poland, Ukraine, and Czech Republic are consistently our most cost-effective Signal markets that still land in reliable success tiers. UK and Germany are slightly more expensive but offer the best first-try success rates specifically for Signal's stricter carrier checks. Check the live pricing section above — rates update in real time with available stock.
Can I receive Signal voice calls on a virtual number?
Signal's in-app voice and video calls don't go through the phone number — they route through Signal's infrastructure peer-to-peer. The phone number is only used during initial SMS verification and account recovery. So yes, once your Signal account is verified, you can make and receive Signal voice and video calls normally — they have nothing to do with the underlying SIM.
How do I pay?
Crypto (BTC, USDT, ETH, LTC via NOWPayments) or credit/debit card. Minimum top-up $2. Unused balance stays in your account indefinitely — no expiry, no subscription, no monthly fees. You pay only when a verification succeeds.
