The number calls out only to the country of the number and to Czechia; calling the country of the number is switched on separately for each country, and the list of your numbers shows where each one calls. We register it with the operator in the name of the provider with an address in that country, usually within 1 business day and no later than 3 business days (within the hour for countries without registration), and the fee is charged only after activation. Calls are billed at the usual rates. You see the current list of countries and the price of a number in each of them when you order, and we keep extending it.
A call out to the number's own country costs from €0.0384/min depending on the country; the number card shows the exact price.
Gate ring
One request rings a GSM gate, lock or box from your number, and the call is never connected. Your number must be on the gate's list of allowed numbers.
- Ringper attempt
- €0.0105
If the target picks up, the connected seconds are billed on top, like a regular outbound call.
SMS to other countries
A text from the shared sender to a mobile number in a country from the offer. The recipient cannot reply. The price is per message segment, the same as for SMS to Czechia: a longer message splits into more segments.

These countries are reached only from the shared sender, not from your own number. For Czechia and Slovakia the SMS rate above applies.
Voice message
One request calls the number you give, reads a text aloud and hangs up. You need neither an agent nor a number of your own, and text-to-speech is included.
- Voice messageoutbound call price, no agent surcharge
- €0.0538/min to Belgium and €0.0384/min to Czechia
Only the outbound minute is billed, per second, and a call nobody answers costs nothing. Not meant for unsolicited marketing.
A connected message from your own number is billed for at least 60 s, for some destinations 90 s.
From your own number in another country (the from field), the rate of an outbound call to the number's country applies, from €0.0384/min depending on the country.
An inbound call costs €0.0209/min with us - Twilio charges €0.273/min for the same thing on a toll-free line.

Pricing FAQ
- How much do 1,000 minutes and 1,000 SMS cost?
- 1,000 minutes of outbound calls come to €38.34, 1,000 SMS to €56.67, €95.00 together excluding VAT. We bill by the second, so a shorter call costs proportionally less (the exception is a voice message from your own number, at least 60 seconds).
- How much does a minute with the voice agent cost?
- The call rate plus the agent surcharge: an inbound call with the agent comes to €0.125 per minute, an outbound one to €0.143. Speech recognition, the voice and the model are all included - nothing else to assemble.
- Do I pay for a number even when it is not in use?
- Yes, €1.63 a month per voice number until you release it. A number from the welcome credit stays yours while you use the account; without a top-up or use, we release it after an e-mail notice.
- Can I have calls and SMS on the same number?
- Yes, with the calls and SMS number: a Prague landline for €2.05 excluding VAT per 30 days that people can call and text. We activate it usually within 1 business day, and SMS from it go only to Czech numbers.
- Can I have a number in another country?
- Yes, with the number in another country: a landline or national number in a country of your choice from €1.21 excluding VAT per 30 days depending on the country; you see the exact price for each country in the offer when you order. People can call it and your agent answers. The number is for calls only, with no SMS: it neither receives nor sends them. It calls out only to the country of the number and to Czechia. We register it with the operator in the name of the provider with an address in that country, usually within 1 business day and no later than 3 business days (within the hour for countries without registration), and the fee is charged only after activation. You see the countries you can choose from when you order in the portal, and we keep extending the offer. An account can hold at most 2 such numbers in one country and 4 numbers from the operator in total, and you can order one only after your first credit top-up.
- How is VAT handled?
- We invoice with Czech VAT at 21%. For a company VAT-registered in another EU country we invoice without VAT under the reverse charge mechanism - just enter your VAT number in account settings, we'll verify it in the VIES registry.
- Does credit expire, and what is the minimum top-up?
- Topped-up credit never expires. You top up by card in amounts of €10, €20, €50, €100, and after verifying your email you get €2 to try things out for free.
- Does Twilio work for Czech phone numbers too?
- Yes, but a Czech local number needs a regulatory bundle of documents that has to be approved - see the Twilio comparison page for details. With volai the number is active right after purchase.
- We bill agent calls by the second, not by rounded-up minutes.
- We invoice with Czech VAT at 21%. For a company VAT-registered in another EU country we invoice without VAT under the reverse charge mechanism - just enter your VAT number in account settings, we'll verify it in the VIES registry.
- We issue a tax invoice for every card payment, and you'll find it in the portal.
- Topped-up credit never expires - it lasts until you spend it.
