I have bought 3 times already and will buy again. Probably the cheapest mobile data solution we can get. However, you have to go to the shop and pay 100 CZK to exchange it for an esim. There is no need for authentication, credit charging, etc. as mentioned here (that's only if someone wants to use an older card without credit, not a newly purchased one).
Cheaper than from O2 directly
You can trade it for an esim for a hundred
with little data usage, it really lasts a year
I got constant unsolicited texts from my first sim. The number belonged to a Mr. Hejduk who tried to take all kinds of loans from different companies every week. Although the sim is data-only, sms and calls can't be turned off, and O2 apparently recycles numbers

Super, for example. for occasional internet access in a place without a fixed connection. Valid for 365 days from activation, with the option to pay for an additional year.
Works for me without problems, I operate in the Czech Republic
Via WEB O2 it is possible to find out the current credit status, receives SMS, probably it is possible to send (I have not tried)
Possibility to subscribe for another 12 months (same card)
Sends SMS when 80 and 100% is used up

There was a 20% discount from the original price. The data works reliably.
The instructions do not specify how to ask for remaining or consumed data.
