Was travelling to Turkey and purchased easySim eSim to get data as roaming charges on my UK sim was exorbitant. Connectivity was good throughout the place we stayed and at airport (we did not roam much). You get data only - no phone number but I did not care much about having to call anyone. I find there are a LOT of eSIM providers nowadays and this wasn't the cheapest but there was a link right on my boarding card which made it easy to remember to get this BEFORE travelling rather than land and go in search of a local shop that had a sim and this reduced stress a lot. Overall - helped me with having data during our stay - no complaints as such.
