If you leave the country without setting up SMS you can’t ever use 2FA. They claim to support adding foreign numbers, support people being abroad, support adding new DigiD accounts from abroad, but oh no you can’t just add a number. Not even by going to an office or doing a virtual interview. I would think this violates EU law on discrimination. If you live in the UK post-Brexit it’s now totally impossible, I believe (since you aren’t even allowed to make a new account).
