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

The SIM card is hopefully fine, but after registering it to my O2 I found that it has been activated for 14 days through a foreign device. What Alza did with it before is a mystery to me. I won't solve it, but I don't have a pleasant feeling about it, next time I'd rather go straight through o2

SIM card purchased in November 2025 and according to O2 it is already active from May 2025, so I don't understand it now that I have unpacked it. Somewhere 7 months are missing.
