It's has 10GB of data, but is only good for one day (I forget it if's one actual day, or 24 hours), after which you need to buy a plan that will be more expensive than using a travel eSIM.
The catch with travel eSIMs is that you can't (legally) buy them once you're in country, and many of the websites are actually blocked, and/or will not sell you a SIM. VPN'ing might work, but I'm not sure if a phone VPN will allow you to install the eSIM or if that might be blocked too (most low-level phone functions avoid the VPN). Buying before you're in country is fine.
