Good to know

Straight answers, before you buy

What your Slovak number does brilliantly — and the few things no second number can do.

Verification codes

Most Slovak apps and websites accept HeyNum numbers. Banking apps and eID-based services rely on your identity and your bank, not just a phone number.

Calling other countries

Your number includes calls and texts to Slovak numbers. Calls and texts abroad use pay-as-you-go credit, with rates shown before you dial.

Keep it or let it go

Your number stays yours while your subscription is active. Cancel in one click and it remains live until the end of the period you've paid for.

No emergency calls

Like most internet phone services, HeyNum can't call emergency numbers. Keep a regular mobile line for emergencies.

How much does a Slovak number cost?

$5.49 a month, or $54 a year — two months free. That single price includes every feature: there's no setup fee, nothing to upgrade, and the price is the same wherever you live.

What's included with my Slovak number?

1,000 minutes and 1,000 SMS a month to Slovak numbers, unlimited incoming calls and texts, visual voicemail with transcripts, call forwarding, schedules and auto-replies, the spam shield and access from all your devices. Calls and texts to other countries use pay-as-you-go credit.

Can I receive verification codes on my Slovak number?

Yes, in real time, right in your browser inbox. Most Slovak apps and websites accept HeyNum numbers. Banking apps and eID-based services rely on your identity and your bank, not just a phone number.

How fast is my number activated?

Instantly. Your Slovak number is assigned and live as soon as your payment is confirmed — open HeyNum in your browser and start calling and texting straight away.

Can I use it outside Slovakia?

Yes. Your number works anywhere you have an internet connection — Wi-Fi or mobile data — with no roaming charges on your HeyNum line. Calls to Slovak numbers use your included minutes wherever you are.

Do I need a Slovak address or ID card?

No — just an email address. Your number works anywhere with internet.
