Unfortunately, one of the four wasn’t charged, and the O2 helpline just laughed at me, saying I could recharge it again for 999, so I’m waiting for my complaint to be processed.
Cheaper than buying directly from O2
It doesn’t have to have ‘credit’ on it

50 GB of data to use as you like throughout the year, not just for a month
It is not possible to purchase an eSIM directly; you must visit a branch in person to convert it – this cannot be done online

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
