Czech Republic mobile top up from anywhere
A Czech Republic mobile top up on ReloadTo works for O2, T-Mobile and Vodafone prepaid lines, for your own number or someone else's, whether you are in Czechia or abroad. Choose the carrier, enter the number, pick a credit amount in Czech koruna (CZK) and pay with a debit card, credit card or PayPal. Czech top-ups range from $15.06 to $105.36 USD, with no extra fees: you pay the price you see.
People also search for this as “cz top up”, “czechia top up” or, in Czech, “dobití kreditu online”. Whatever you call it, the credit goes straight to the prepaid line.
How to write a Czech mobile number
The Czech Republic uses a closed 9-digit numbering plan with country code +420. Enter +420 and the 9-digit mobile number. Czech numbers have no leading 0: 602 123 456 is written +420 602 123 456. Don't add 00 or 011.
According to the Czech Telecommunication Office, mobile numbers start with 6 or 7. Numbers can move between carriers, so the first digits don't always tell you the carrier: confirm it with the person who uses the line.
O2, T-Mobile or Vodafone: what you can send
According to our catalog, all three Czech carriers get prepaid credit in CZK, not bundles. The credit can then be used for calls, SMS, data or the carrier's own packages.
| Carrier | Credit amounts in our catalog | Check the balance (official) |
|---|---|---|
| O2 | 300, 500, 700, 1,000 CZK | *104*# or Moje O2 |
| T-Mobile | 300, 500, 600, 700, 1,000 CZK | *101# or SMS KREDIT S to 4603 |
| Vodafone | 350 to 2,100 CZK | *22# or SMS KOLIK KREDIT to 7700 |
Each product shows the CZK credit and its price in dollars before you pay.
How a Czech top-up works on ReloadTo
- Choose the carrier: O2, T-Mobile or Vodafone.
- Enter the number with +420 and 9 digits.
- Pick the credit amount in CZK.
- Pay. Pay with a debit card, credit card or PayPal. Card payments use 3-D Secure, and sometimes we ask you to verify your card before the order is sent.
The top-up is sent automatically once the payment is approved. If a top-up fails, we refund you. A completed top-up to a wrong number can't be refunded, so check the number before you pay.
Why top up a Czech number online
You don't need a coupon, a shop or an account with the carrier. O2 says its own online card top-up needs a card issued in Europe; on ReloadTo you can pay with a debit card, credit card or PayPal from anywhere. That helps students, workers and travellers with a Czech SIM, and anyone topping up a line in Czechia from another country.
