On Viber, your number is your identity — just like WhatsApp. Activate a second Viber line on a number you own: permanent UK numbers for keeps, temporary from $0.50 for quick signups.
In the Balkans, Eastern Europe, the Middle East and the Philippines, business happens on Viber. Give it a number that isn't your personal one.
Marketplace buyers, clients and community groups reach a line that exists for them. Your personal Viber — and personal life — stay untouched.
Viber re-checks the number periodically and at new installs. The permanent eSIM number receives those SMS worldwide, so the line survives every trip and every new phone.
Viber rejects most app-based VoIP numbers at activation. Real carrier numbers — which is what eSIMfly provides — activate first time.
Permanent UK eSIM for a lasting line, or a temporary number from the dashboard for quick use.
Use the number at Viber activation instead of your own.
The activation SMS arrives in seconds. Enter it and your new Viber line is live.
💡 The number IS the account on Viber. Viber periodically re-verifies your number and requires it again at every reinstall. If the number is gone, so is the account — contacts, groups, history. For any Viber line you plan to keep, use the permanent O2 SMS eSIM ($9.87/30 days) rather than a one-time number.
Yes. Viber requires a phone number at activation, but it doesn't have to be your personal one. Buy a number in your eSIMfly dashboard, enter it in Viber, and the activation code arrives within seconds.
Viber blocks many known VoIP ranges. eSIMfly temporary numbers come from real carrier ranges, and the permanent option is a genuine UK mobile number on the O2 network - both activate Viber reliably where VoIP apps fail.
Yes, and it's the key thing to understand. Viber periodically re-verifies your number, and losing access to it means losing the account. For a Viber line you'll actually use, choose the permanent O2 SMS eSIM ($9.87/30 days) - a one-time temporary number suits only short-lived accounts.
The same reasons as a second phone: business contacts in markets where Viber dominates (Eastern Europe, Balkans, Middle East, Philippines), online listings and marketplaces, or communities you'd rather keep away from your personal number.
Yes. Once activated, Viber works over any internet connection. The permanent eSIM number also receives re-verification SMS worldwide, so the account keeps working wherever you travel or move.
Within seconds. Viber sends the SMS immediately and it appears on your eSIM or dashboard in real time. Activation takes about two minutes end to end.
