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.

A whole year of peace. I have 100 Gb per month, so roughly 3.3Gb per day, which is fine with me. Sim router with ups and there is internet even without power. Nothing crashes and it's running. I'm satisfied.

a solution if you don't need to draw data with a regular limit, but occasionally in bursts. Sufficient for my needs and more convenient than the monthly plan

a lot of data for reasonable money
cheaper than O2
transferring SIM to e-sim a terrible problem, you have to go to a branch to verify that you are not a hacker, where they tell you that you have to top up your credit worth at least 300 crowns, then they do a verification for transfer to esim (after 24 hours), but the lowest amount for topping up is 350 crowns, which you will forfeit in half a year, because the SIM is not for texting or calling.
knowing that there will be a problem on the conversion to esim, so I don't buy

For a chat is the ideal solution, at the price of 250, -/month I have in 5g modem 190/28 Mbps with a limit of 1000 Gb/year, in winter I use less, in summer more. So a better solution than a monthly limit.
500, - cheaper than o2
I don't have to deal with anything for a year
