I can't log in to the web version using my phone number
Accounts created by telephone number cannot be used to log into the Yandex.Music web version and Yandex.Radio. You can only use this type of account on a single device. If you want to synchronize your music in the app with the web version and Yandex.Radio, sign up for an account via Yandex or social networks.
If you signed up for a subscription using an account based on a phone number, email customer service and we will transfer the remaining paid days to a different account.
It is not possible to transfer tracks that you downloaded. You can, however, copy your playlists to a different account.
