Oskarta is a Vodafone Czech Republic MVNO.
It may actually be a Vodafonbe Czech Republic sub-brand, but this is not something I can confirm (yet).

Coverage – Oskarta
Oskarta is a Vodafone Czech Republic MVNO, meaning Oskarta uses the Vodafone Czech Republic network and does not have its own mobile infrastructure.
To find out what to expect in terms of coverage with Oskarta, jump to the Vodafone Czech Republic Coverage section in my Czech Republic SIM card buying guide.
SIM Card Price – Oskarta Czech Republic
You can buy an Oskarta SIM card for 100 CZK with 100 CZK credit in newsstands, kiosks & gas stations. Oskarta Mobil SIM cards are not sold at Václav Havel Airport Prague (PRG).

- Find out how much SIM cards cost in every country, including data-only SIM cards and tourist SIM cards, offered by each mobile operator + information about starter benefits (lookup tool)

It is also possible to get an Oskarta eSIM for the same price as a regular SIM card.
You may want to get a travel eSIM for the Czech Republic, which can be cheaper than getting a SIM card from Oskarta (in some cases).
Especially when getting a Europe-wide eSIM if you do not stay in just the Czech Republic or a global eSIM valid for up to a year if you want one eSIM to work practically worldwide.
My Czech Republic eSIM buying guide analyzes various eSIM options of eSIM providers I have tested extensively worldwide.
Here is a quick introduction to them:
- Airalo: O2 (Czech Republic only), Eurolink (39 countries in Europe) & Discover+ (130 countries worldwide + call and text feature) – use code NEWTOAIRALO15 (15% off – first-time users only) or AIRALOESIM10 (10% off)
- Alosim: Czech Republic & Europe (32 countries) – use code PTW (5% off – no limits)
- Holafly: Czech Republic & Europe (32 countries) – these eSIMs have unlimited data + calling feature – use code PHONETRAVELWIZ (5% off – no limits)
- Nomad: Czech Republic, Europe (up to 35 countries) & Global (up to 139 countries) – use code ADU123 (3 USD off – first-time users only)

But let's continue with Oskarta for now.
Top-Up, Recharge & Balance Check – Oskarta
Packages, Plans, Bundles & Offers – Oskarta
Oskarta has no (data-)featured prepaid plans. Instead, only Pay As You Go rates are available.
I will list all the prices in CZK (Czech Koruna).
To convert CZK to your currency (let's say EUR – Euro) with up-to-date exchange rates, use the Wise Currency Converter tool.

For data, you will be charged 1 CZK for 1 MB.
Normally, I would not even include a mobile operator (or MVNO for that matter) with such outrageous rates.
However, if you use more than 77 MB (77 CZK) but less than 1 GB, you will only be charged 77 CZK.
This 1 GB will stay valid for one month.
If you go over your 1 GB allowance, you will be charged another 77 CZK for another 1 GB for 1 month.
77 CZK for 1 GB of data is below average in the Czech Republic, so it is a worthy option to consider.
