How to transfer Telegram data to a phone without root or run the program through tor before activation?

Question

Android

Changed one ancient Samsung phone to a newer model. The old one was rooted, the new one is not yet. Telegram was activated on the old one even before the locks. When he is already logged in, the regular blocking bypass works. You can manually configure the proxy. But on the new phone, I could not send SMS for the initial registration. As I understand it, the means to bypass blocking at this stage do not work, so after entering the phone number, the "loading" indicator is spinning and nothing happens. Now the main questions:
1. Is it possible to transfer account data without rooting a new phone?
2. Is it possible to use other programs to launch telegrams through the proxy before access to its settings appears?
3. Can there be alternative registration options?
