Rent a number for Viber
Rent a number to register Viber and receive the activation code
Viber activates by number and lives on a single device: moving the account to another phone means re-activation with a new code. The desktop version does not work at all without an active mobile account. A physical number on a real SIM covers both operations — the first activation and the repeat one when the device changes.
How Viber checks the number
If the SMS does not arrive, Viber offers a callback and dictates the code by voice — on a rented number this path works and is often faster. A separate quirk is that Viber is tightly bound to the country code: the number and the country chosen at registration must match, otherwise activation breaks halfway.

FAQ
Viber offers a call instead of an SMS — will that work?
Yes. The Viber callback reaches a rented number and dictates the code by voice. If inbound calls are not included in your plan, wait for the SMS to be resent.
Can I use Viber on a computer?
Yes, but only after activating on a phone: the desktop version attaches to an already working mobile account and needs no separate code.
What happens when I change devices?
Viber will require a fresh activation with the same number. While the rental is active, the code arrives in your dashboard as usual.
Why does activation break at the country step?
The country in the app must match the number's code. Pick the country of the rented number — it is shown on the rental card.
