Starting a trip around Europe in a week, need esim advice

I will be starting my journey from Finland next week, and I wanted to ask for a recommendation for mobile data. I plan to only have my phone during the drive to work as a router, and it only takes eSIMs. This is why I’m planning to get a travel eSIM provider, something like Saily (it’s relatively new, but it’s exactly what I need in terms of data). I am not staying in one spot for too long, so the variety of plans+the amount of data ratio is good. Has anyone used it yet, any reviews? What do you use for your internet providers while switching through countries?
