About prepaid services

With the O2 prepaid service you call without a contract. Simply get a  mobile phone and a prepaid O2 card, choose a  prepaid tariff and you can start calling immediately. When you need to recharge your O2 card with prepaid credit, you have several options. At the same time, you always have an overview of how much credit remains on your phone.

Prepaid tariffs

With your prepaid phone you get several prepaid tariffs to choose from. Make your selection according to a variety of categories - for example, according to whether you prefer calling or sending text messages.

More information

Credit check

On the display of your prepaid phone (or in its menu, depending on the model you own) you can see the current amount of credit that you have left. This amount is updated after every call you make.

You can find out the current state of your credit by calling the customer care line at *11 or by dialing *104*# and pressing the call button.

For SMS messages, this depends on how often you send them. Your credit is updated:

• after every ten messages - when you send messages frequently
• once a week - when you send messages infrequently
• after every SMS message you send - if your credit is less than CZK 15
• on request by calling the *11 customer care line - when you need to get a credit status update in less than a week

O2 Recharging

You can recharge your calling credit anytime. Methods of doing so include coupons, through automated tellers and SAZKA terminals, from fixed lines, via bank transfer, and several other ways.
