How to Verify Signal Without a Local SIM Card

Yes, in most cases — you do not need a SIM card from the country, you need a number you control that can receive the code. Signal can deliver the code by SMS or by an automated voice call, so a number that cannot receive texts may still complete verification over the call. Signal accepts some virtual numbers and refuses others, so the outcome depends on the specific range. Because Signal allows one account per number, a number that anyone has already registered cannot be used again — which is why shared numbers from free receive-SMS sites almost always fail. DialAnyone numbers in 12 countries support inbound SMS and are private to a single account.

How Signal verification works

Signal requires a phone number for registration and verifies it with an SMS code or an automated voice call.

The thing that catches people out

Signal is more tolerant of virtual numbers than WhatsApp, and its voice-call option makes voice-only numbers viable. Registering moves your Signal identity to the new number, so anyone messaging your old number will not reach you.

Frequently Asked Questions

Can I verify Signal without a SIM card?
Yes. Signal needs a phone number that can receive the verification code, not a physical SIM. A virtual number assigned to your account receives the code in your browser or app. Signal also offers an automated voice call, which is useful when SMS is blocked.
Why do free Signal verification numbers never work?
Those numbers are shared public inboxes used by thousands of people. Since Signal permits one account per number, someone almost certainly registered it before you. The ranges are also widely blocklisted, so the code is often never sent. Anything arriving there is readable by anyone.
Does the number have to be from my own country?
No. Signal accepts numbers from many countries; what matters is that the number can receive the code and that you control it. Choosing a country whose numbers support inbound SMS matters far more than matching your location.
Will a Signal code arrive on any virtual number?
Usually, on a private dedicated number. Signal accepts many virtual ranges, though it can refuse specific ones. A number nobody else has used gives the best chance.
What is the most common mistake?
Signal is more tolerant of virtual numbers than WhatsApp, and its voice-call option makes voice-only numbers viable. Registering moves your Signal identity to the new number, so anyone messaging your old number will not reach you.
What happens if I lose access to the number?
Signal uses the number for recovery as well as sign-up, so losing it can mean losing the account permanently. Keep the number active for as long as the account matters, and move verification to a new number before letting the old one lapse.
