While it is the cheapest card with data for a year, it is not worth it if you require eSim. You have to physically go to a branch to activate it, where they can also tell you: "We're out of QR code papers, come back in a few days when they arrive. And if they already have the QR papers, they ask for 99 CZK from the transfer to eSim at the branch (you can't do it via My O2 or the info line). Crazy O2 in prehistoric times. Otherwise, of course, 50GB is much better value for money, and even the 99 CZK for the transfer to eSim at the branch is better "dissolved in the price".
The cheapest solution
Disadvantageous in terms of price/volume
Flying around O2 branches for eSim

Unfortunately the Goodwe inverter doesn't work with it, O2 has tighter network security and firewalls on its mobile tariffs that evaluate outgoing inverter communication as a threat and block it.

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
