In India, I’ve been using eSIM for a few years now (on iPhone, not Android). It’s been working quite well. Transferring eSIM from one iPhone to another works fine. Activation of an eSIM takes a few hours, at the most. Due to regulations, there are restrictions placed on sending and receiving SMSes for the first two days.

The only hindrance I’ve seen is that to get an eSIM in the first place, an SMS has to be sent from the phone even though the eSIM activation QR code is sent over email (and the registration of an email address is also possible online). In some cases, like switching from one type of plan to another (postpaid to prepaid), this would require getting a physical SIM card (that’s the default for any connection), using it from a phone that has a physical SIM slot and then using that for the SMS.
