Which Hong Kong carriers we run

Hong Kong ProtonMail 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 HKT (PCCW Mobile), 3 Hong Kong (Hutchison) or one of the MVNO brands that ride those same networks: SmarTone, China Mobile Hong Kong, China Unicom Hong Kong, HKBN. All real mobile-network SIMs, not VoIP. ProtonMail's anti-VoIP detection (the same check that rejects Google Voice and Twilio numbers) sees these as regular Hong Kong mobile lines because that's what they are.

Five real reasons people verify Proton Mail without their personal number

None of these are sketchy. Privacy-conscious people specifically choose Proton Mail to keep their identity separate — giving Proton your real phone number undermines the whole point.

Giving Proton your personal number defeats why you chose Proton

Proton Mail's value proposition is email that isn't tied to your identity. But when Proton asks for phone verification at signup, giving it your real SIM links your private inbox to a number registered in your name with a carrier. A virtual number gives Proton the verification signal it needs without handing over a personally identifiable number.

A second secure mailbox for personal vs professional vs anonymous use

Proton accounts are linked one-per-number in their anti-abuse system. If you want a dedicated inbox for activist work, journalism, sensitive negotiations, or simply keeping professional and personal email separate — each inbox needs its own verification number. A virtual number makes that affordable without carrying extra SIM cards.

VoIP numbers (Google Voice, TextNow, Twilio) are rejected at Proton signup

Proton's anti-abuse filter actively blocks VoIP number ranges — the same ranges that most 'free virtual number' services use. If you've tried TextNow or a Twilio number and seen an error, that's why. Physical SIM numbers from real carriers don't carry those flags and pass Proton's check.

Your existing Proton account is locked — recovery requires the original number

If you set up two-factor authentication on a Proton account and lost access to the number, account recovery is difficult. Some users create a fresh account while resolving the old one. A virtual number lets you get a clean inbox instantly while you work through Proton support on the locked account.

Data-only SIMs and eSIMs can't receive Proton's SMS codes

Modern 5G eSIMs and travel data plans skip SMS capability. Proton's phone verification only works via inbound SMS — your data-only SIM won't receive it. A real-SIM virtual number solves this in under a minute.

Proton Mail-specific problems and how to fix them

These are the actual failure modes we see on Proton Mail verifications. Each has a specific cause — don't retry blindly.

"Phone verification failed" or number rejected before any code is sent

Why it happens

Proton's anti-abuse filter rejected the number range as VoIP or known-shared. This happens at the submission step, before an SMS is even attempted. Affects VoIP numbers and some shared ranges — real SIMs from clean carriers don't trigger this.

The fix

Cancel the activation on VirtualSMS for a full refund — no SMS was sent, so no charge applies. Select a Tier 1 EU country (Poland, Netherlands, Czech Republic) and retry. If you're using a free shared inbox and seeing this error, that's expected — free shared numbers are mostly VoIP-ranged and Proton blocks them.

"This phone number is already associated with a Proton account"

Why it happens

Proton allows one account per phone number globally. A previous user of this specific SIM created a Proton account with it that still exists. Proton does not release that binding when an account is inactive.

The fix

Cancel for a full refund and get a fresh number from a different country. Polish, Dutch, and German numbers have the lowest prior-association rate in our fleet because those SIM batches rotate faster. Don't retry the same number — the binding is permanent on Proton's side.

Code never arrives within 2 minutes

Why it happens

Either Proton's SMS gateway is slow on the route to this specific carrier, or the SIM is temporarily rate-limited. Not an account issue — it's a network path issue.

The fix

Cancel for a full refund. Try a different country from Tier 1 — Poland and Netherlands have the most consistent SMS delivery speed for Proton in our fleet. Don't keep hitting 'Resend code'; each resend resets Proton's internal timer.

Proton offers only an email verification option — no phone prompt appears

Why it happens

Proton Mail does NOT always require phone verification at signup — it depends on the signup path (web vs app), IP reputation, and anti-abuse signals at that moment. Phone verification is triggered when Proton's system flags the signup as higher-risk. If you're not seeing a phone prompt, you don't need a virtual number — use email verification instead.

The fix

No action needed on the VirtualSMS side. If you bought a number before realising phone verification wasn't required, cancel immediately for a full refund — the refund window is 20 minutes from purchase if no SMS was sent.

Code arrives but Proton says it's wrong or expired

Why it happens

Proton's verification codes expire in a short window. If you requested multiple codes, only the most recent is valid — earlier ones are invalidated the moment Proton sends a new one.

The fix

Always use the MOST RECENT code in your VirtualSMS inbox. If you see multiple Proton codes in your inbox, ignore all but the latest. If the latest code also fails, the session may have timed out — cancel for a refund and restart the Proton signup flow fresh.

Account locked after signup — Proton asks to re-verify via the phone number

Why it happens

Proton's post-signup checks triggered a hold — common when signing up via VPN, or when account activity looks unusual. They route recovery via the verified phone number.

The fix

If you used a pay-per-activation number, it's been released and can't receive new codes. This is the primary reason to rent rather than activate-once for Proton accounts you need long-term or access via Proton Unlimited. Contact VirtualSMS support if this happens within 24 hours — in some cases we can return the number for the re-verification window.

Proton asks for an alternative verification (captcha or email) instead of accepting the phone code

Why it happens

Proton routes some signups through a captcha + email flow when phone verification isn't enough by itself, or when the account shows other risk signals. This isn't a virtual number rejection — Proton accepted the number but added an additional step.

The fix

Complete the captcha and email step alongside the phone verification. Both can coexist. Your VirtualSMS number is still valid for the phone step — look for the phone code in your dashboard and enter it when prompted.

Frequently asked questions about Proton Mail virtual numbers

Does Proton Mail always require phone verification at signup?

No — Proton triggers phone verification selectively, based on anti-abuse signals at signup time. Factors include: signup path (web vs mobile app), IP reputation, VPN usage, and how many accounts Proton has seen from that session. Many signups complete with email verification only. If you see a phone prompt, it means Proton's system flagged your session as higher-risk and wants a secondary identity signal.

Will Proton Mail detect and reject a virtual number?

Proton detects and blocks VoIP number ranges — the same carrier ranges used by Google Voice, TextNow, TextFree, and most free virtual number services. It does NOT systematically block real carrier-issued SIM numbers. VirtualSMS operates physical SIM cards on real carrier networks — those numbers clear Proton's VoIP filter. The distinction is carrier range and number history, not 'virtual vs real.'

Why does Proton Mail want a phone number when it markets itself as privacy-first?

Proton uses phone verification as an anti-abuse signal at signup — not to track you post-signup. Once the account is created, Proton does not use your phone number to correlate your identity or share it with third parties. The phone is a one-time friction gate to reduce automated account farming. That said, the principle still applies: giving Proton your personal SIM links a personally identifiable number to your private inbox. A virtual number satisfies Proton's check without that linkage.

Can I use the same virtual number for multiple Proton Mail accounts?

No. Proton allows one account per phone number globally — this is their anti-abuse design, not our limitation. Once a number has been used to verify a Proton account, Proton binds it permanently. To create a second Proton inbox, you need a second number.

What happens if I need to recover my Proton account later?

If you used a pay-per-activation (single-use) number and set it as your SMS recovery contact in Proton, recovery won't work — the number has been released. For accounts you need long-term, either: (a) use Proton's TOTP authenticator app for 2FA (no phone needed for recovery) or (b) rent the number so it stays available during the rental period. We recommend against setting a single-use activation number as your Proton recovery contact.

How long does Proton Mail verification take end to end?

Under 3 minutes typically. Signup → buy number → SMS arrives (usually 15–30 seconds) → enter code → done. If nothing arrives in 2 minutes, cancel for a full refund and try another country — don't keep retrying with the same number.

What's the cheapest country for a Proton Mail number?

Poland, Czech Republic, and Ukraine are consistently our most cost-effective Tier 1 options for Proton Mail. They're cheaper than UK or Germany and still land in the highest success tier. Check the live pricing section above for current per-country rates — they update with available stock.

Can I use this for Proton VPN or Proton Drive as well?

The phone verification at signup applies to the Proton account itself — which is shared across Proton Mail, Proton VPN, Proton Drive, and Proton Calendar. One verification with a VirtualSMS number gives you access to the full Proton ecosystem under that account.

How do I pay?

Crypto (BTC, USDT, ETH, LTC via NOWPayments). Minimum top-up $2.50. Unused balance stays in your account indefinitely — no expiry, no subscription, no monthly fees. You pay only when a verification succeeds.
