I bought an annual data SIM card with 50 GB of data for 1000 CZK and I must say that I was pleasantly surprised. The price for a full year's data is very reasonable, especially considering that it comes out to about 4.16GB per month. This is perfectly sufficient for my needs for normal internet use such as web browsing, social networking or listening to music online. Another advantage is that I don't have to worry about renewing the package monthly or watching my consumption every month. On the other hand, however, it is more than obvious that the operator's pricing strategy is aimed at attracting customers to purchase the largest package with 1 TB of data for CZK 3,500. The difference between the offers is significant, not only in the amount of data, but also in the price per 1 GB. The mid-range offer could be more attractive if, for example, it offered 100 GB per year, which would better suit users with medium data consumption.

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
