Forgive me, I discarded xapo a long time ago lol. (If I'll be born again, I'm pretty sure I'll do the same thing)
Anyway, You must be talking about this?
https://support.xapo.com/how-do-i-log-into-my-xapo-account/view=faqIt is stated there that the verification code is automatic but not on ios which means you have to enter it manually there. That said, maybe it's possible to access your account by:
1. Hire someone to just receive the code (the SMS) - From what I remember, it cost $3-$5
2. Install an ios emulator =

4. Enter the code manually.
Those steps won't help without a phone number to actually give my account. I have to add that before I can do anything else. Thanks for your suggestions though.
