Haven't used on iPhone, but using it (Jio) on Android (Pixel 3a). When I have first converted the SIM to electronic, incoming did not work. Nobody had a clue as to why. Customer care didn't help much except for giving instructions to disable call forwarding. Jio store people then converted it for the second time and even then it didn't work for some time. However, it started working after a few hours automatically. Strangely, this issue wasn't there with the outgoing, it was working fine. Apart from this, rest all like call quality and data are fine! No issues at all. Jio store people were saying this was the first time they have used an eSIM in android phone, as mostly they did it for iPhone. They also mentioned they never faced this incoming issue on iPhone eSIM.
