Minutes convert the monthly credit into inbound calls with the agent after paying for one number; the credit itself covers the whole price list. “Best value from” assumes 2-minute calls: from that many calls a day the tier is the cheapest option, cheaper than paying by the second too.
Per-second billing and top-ups stay exactly as they are, and topped-up credit does not expire. The plan is optional: its monthly credit expires at the end of the period, topped-up credit does not.

Pricing FAQ
- How much do 1,000 minutes and 1,000 SMS cost?
- 1,000 minutes of outbound calls come to 920.00 CZK (~EUR 38.33), 1,000 SMS to 1,360.00 CZK (~EUR 56.67) - 2,280.00 CZK (~EUR 95.00) together, excluding VAT. Billing is per second, so shorter calls cost proportionally less.
- 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 3.00 CZK (~EUR 0.13) per minute, an outbound one to 3.42 CZK (~EUR 0.14). 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, 25.00 CZK (~EUR 1.04) a month per voice number, deducted from your credit. You can release a number at any time and the fee stops. A number from the welcome credit stays yours while you use the account; if you have not topped up and do not use the account, we release it after an e-mail notice, and your account, agent and credit stay.
- Can I have calls and SMS on the same number?
- Yes, with the calls and SMS number: a Prague landline number for 49.00 CZK (~EUR 2.04) excluding VAT per 30 days that people can call and text, and that your agent places calls and sends SMS from (SMS from the number cost 2.50 CZK (~EUR 0.10) per segment). Received SMS are included and calls are billed at the usual rates. We register the number with the operator, usually within 1 business day (no later than 48 hours), and the fee is charged only after activation. SMS from the number go only to Czech numbers and without delivery reports, we do not guarantee verification codes from services, and receiving SMS has been verified on the O2 network. An account can hold at most 2 such numbers, and you can order one only after your first credit top-up. A voice number (25.00 CZK (~EUR 1.04) a month) cannot receive SMS, and an SMS number (a Czech mobile number for SMS only) has no calls.
- Can I have a number in another country?
- Yes, with the number in another country: a landline number in a country of your choice for 49.00 CZK (~EUR 2.04) excluding VAT per 30 days, the same as the Prague number. 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?
- All prices exclude VAT. When you pay by card, 21% VAT is added and you get a tax invoice. VAT-registered businesses from other EU countries with a verified VAT ID pay without Czech VAT (reverse charge).
- Does credit expire, and what is the minimum top-up?
- Topped-up credit never expires. You top up by card in amounts of 200 CZK, 500 CZK, 1,000 CZK, 2,000 CZK, and after verifying your email you get 50 CZK 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.
- What happens when I use up the monthly plan credit?
- When you turn on the plan you pick one of two options. Either topped-up credit is bought from the saved card in steps of 200 CZK (auto top-up, with its own limits), or a cap applies and nothing is bought: once both the monthly and the topped-up credit are used up, outbound calls, SMS and purchases are refused until the next renewal or until you top up by hand, while inbound calls are still answered up to a debt of 50 CZK. With the cap you pay at most the price of the plan. You can change the choice in the portal at any time.
- What if I cancel the plan?
- The plan runs until the end of the period already paid, and you can spend the monthly credit until then. The prorated part of the price is not refunded and no further charge for the plan is made (auto top-up, if you have it on, keeps running until you turn it off). Topped-up credit stays refundable and the account keeps working, billed by the second. You can undo a cancellation until the end of the period.
- What if the card payment for the plan fails?
- We try the charge three times: on the renewal day, after 2 days and after 4 days. After the first failure we email you a link to pay manually and to change the card. Until it is paid no monthly credit is added and the account runs on topped-up credit only. If the third attempt fails too, the plan ends; topped-up credit and the account keep working.
- We bill by the second, not by rounded-up minutes.
- Prices exclude VAT; it's added when you pay by card.
- 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.
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.
