Good to know

Straight answers, before you buy

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

Verification codes

Most Czech apps and e-shops accept HeyNum numbers. Banking apps and BankID verification are tied to your bank account, not just a phone number.

Calling other countries

Your number includes calls and texts to Czech 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 Czech number cost?

$4.49 a month, or $44 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 Czech number?

1,000 minutes and 1,000 SMS a month to Czech 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 Czech number?

Yes, in real time, right in your browser inbox. Most Czech apps and e-shops accept HeyNum numbers. Banking apps and BankID verification are tied to your bank account, not just a phone number.

How fast is my number activated?

Instantly. Your Czech 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 Czechia?

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 Czech numbers use your included minutes wherever you are.

Why is a Czech number cheaper than others?

Our prices follow what each number costs us in its country, and Czech numbers are among the most affordable. You get exactly the same features as with any other HeyNum number.

Do Czech numbers start with 0?

No. Czech numbers have 9 digits with no leading 0. From abroad, add +420 in front.
