Banca Transilvania accepts RON transfers to the T212 RON account. Their transfer fee is 10 lei.
Others have tested Unicredit and said that their RON transfers to the T212 RON account are completely free (haven’t been able to test this myself).
Plus, you can transfer via Revolut, but with a 25 lei fee.
I used my personal card from Transylvania Bank (Banca Transilvania) and the transfer worked just fine.
It took me about two days to receive the money in my account (faster than I expected) and I was notified by email when they entered. You can also check the history when the money reaches the account.
The transfer commission was 10 lei equivalent to approximately 2.05 euros.
Do not forget to use the provided code as a play mention to be sure the money riches de right account!
LE: I draw attention again that my account on 212 is opened in lei.
