Urgh some of those are crazy expensive. Best to pick by destination if you can.
For example they charge you $23 for 10 gig in Central Asia there but if you get a local eSIM it’s $5 for the same and $10 for unlimited. I just WiFi hopped because there was bugger all reception out there anyway.
they also work as soon as you get off the plane! so you don't have to waste time buying an overpriced SIM at the airport while jet-lagged in a foreign language at a kiosk that may be closed.
