Recently I tried to reinstall an eSIM on my Android phone while overseas but was told by my carrier that the eSIM can only be activated while connected to antennas located in the carrier's country, i.e. it can't be activated overseas, despite my plan supporting call roaming and both countries being in the EU.
I don't know whether this is carrier-specific or the same for all carriers.
