Unisim - physical SIM with eSIM support

I can activate a SIM card in RF (I will bring it to Cyprus on August 17th. Larnaca). Or I will sell a unisim separately (this is a physical SIM with an app, on which you can record an e-SIM. That is, even if the phone does not support e-SIM, it will be able to work with them) - unisim 30 euro - activate e-SIM there in RF 20 euro. No power of attorney needed if anything. I myself have encountered the problem of losing a number to which everything is tied, and that even new e-SIMs from this year do not work if they are not activated in the territory of the RF
