I was able to connect to Serbia, Bosnia and Herzegovina, Montenegro, Albania, North Macedonia, Bulgaria, Romania, and Turkey, but as soon as I entered Kosovo from Albania, the connection was lost. I asked support to check, and they told me that only local SIM cards can connect in Kosovo. The support response was quick and courteous.

After we purchased the eSIM, the QR code of it was received in my email. We completed the installation in just a few minutes. I'm very glad that its appearance has solved the network problems we were facing.
