Can I activate Viber with a temporary phone number?
Yes, as long as Viber sends the code by SMS. Buy a phone number for Viber on TempSMSVerify, enter it on Viber's activation screen and wait for the 6-digit code in your dashboard. Viber sometimes uses a flash call instead, which a text-only number cannot catch. If no SMS arrives, you get an automatic refund.

How does the Viber verification code work?
Viber ties every account to a phone number. When you activate the app, Viber verifies that number in one of three ways: a text message with a 6-digit code, a flash call (an automatic call you do not answer, where the code is part of the caller's number), or a voice call that reads the code aloud.
Viber picks the method itself, and in many regions it tries the flash call first. TempSMSVerify numbers receive SMS, so the text message route is the one that works here. If the screen asks you to check an incoming call, wait for the option to receive a code by SMS or cancel the number.
Viber's primary device rule
Viber runs on one primary device, the phone that activated the number. Viber Desktop and tablets link to that phone with a QR code and do not need their own SMS. If the same number is activated on a different phone, Viber moves the account there and the old phone stops working.
That is why a temporary number fits a second account you plan to run from one phone, for example a business line kept apart from family chats. It is not meant to be activated again months later, because by then the number is no longer yours.
- Keep a work or shop Viber account separate from your personal one.
- Test a Viber chatbot or community from a clean account.
- Join Viber groups while traveling, when your home SIM cannot receive texts.
Phone number for Viber: common errors and fixes
Viber's own troubleshooting advice comes down to two things: check the country code, and stop requesting new codes, because each request can lengthen the cooldown.
| Message or problem | What it usually means | What to do |
|---|---|---|
| Waiting for a call | Viber chose flash call or voice activation | Wait for the SMS option. If it never appears, cancel after about 2 minutes for a refund |
| Activation code not received | Viber has not sent the SMS, or delivery failed | Wait a few minutes before you resend, then cancel if nothing arrives |
| Too many attempts | Repeated requests triggered a cooldown | Stop retrying and come back later with a fresh number |
| Activation failed | Viber declined that number or range | Cancel and try another country |
| Wrong code | A typo or an older code | Enter only the newest code shown in your dashboard |
Pay only if the Viber code arrives
When you buy a Viber number, TempSMSVerify freezes the price in your balance. The charge goes through only when an SMS reaches the number. If Viber never texts the code, for example because it insisted on a flash call, the full amount returns to your balance automatically when the number expires or when you cancel.
The number is reserved for up to 20 minutes. While it is active you can ask Viber for another code at no extra cost. After it expires, you cannot reactivate Viber on that number, so back up your chats to Google Drive or iCloud from Viber's settings if the account matters to you.
Use Viber numbers responsibly
Use TempSMSVerify only for Viber accounts that belong to you, and follow Viber's Terms of Use. Bulk messaging, spam, scams, impersonation and coming back after a ban break Viber's rules and ours. Read our Acceptable Use Policy at /acceptable-use before you buy.
FAQ
Viber verification FAQ
How many digits is the Viber activation code?
Viber's SMS activation code is 6 digits. With a flash call, the code is hidden in the caller's number instead, and Viber may read it automatically on Android. TempSMSVerify shows SMS codes only, so look for the text message option. Each new request replaces the old code, so use the latest one.
Why is Viber calling instead of sending an SMS?
Viber decides the activation method based on your region and the number, and it often prefers a flash call because it is quick. A temporary number from TempSMSVerify cannot receive that call. Wait for Viber to offer the SMS code. If it does not, cancel after about 2 minutes and your balance is refunded in full.
Can I use Viber on a computer with a temporary number?
Yes, but Viber Desktop is a companion app. You first activate Viber on a phone with the number, then scan the QR code shown on your computer. The desktop app does not need a second SMS. If the phone loses the account, the desktop link stops working too, so keep the phone app installed.
Can two Viber accounts use the same phone number?
No. Viber links one account to one phone number. If someone activates the same number on another phone, the account moves there and the first phone is logged out. That is the main reason a temporary number suits short-term or single-phone use, not an account you expect to restore years later.
What if my Viber code never arrives?
Wait a few minutes before you resend, because repeated requests can extend Viber's cooldown. If nothing reaches your TempSMSVerify dashboard, cancel the number once the button unlocks after about 2 minutes. Your frozen balance is returned automatically and in full, and you can try another country right away.
Will I lose my Viber chats when the number expires?
Not while Viber stays installed and active on the same phone. The risk comes if you reinstall or change phones, because Viber would ask to activate the number again. Turn on Viber's chat backup to Google Drive or iCloud, and move the account to a number you own if you plan to keep it long term.
