I was referring to cheap part. It is 5 times more expensive than local sim, it is data only, doesn't have phone number I needed for local services. I am not sure hotspot is not blocked or not. The website doesn't say.

Hotspot isn't blocked. I'm using it right now. The reason it probably doesn't offer phone services is due to KYC stuff. Most governments love ID cards, address proofs and what not before they let you make phone calls. The data only esim bypasses all that. In fact, even the data is not locally terminated although you are using the local network. It terminates in their network (hosted by OVH in the EU at the moment). So it also effectively acts as a vpn. This is also great because most governments around the world have arbitrary censorship. Overall, I would say that it's a good product although the prices can be lower.
