For some weird reason, when im travelling with wifi calling, receiving sms messages is a crap shoot. I basically dont get them if theyre sent by a gov agency, bank, etc. I do still get them from android phones. Its weird, i have no idea why.

And, in my experience, Android pushes you heavily to enable RCS; every time you open its messages app, there's a chance that it will randomly ask you to enable it, with a large button to enable and a small link to dismiss the dialog without enabling. I never tried, but I expect that once enabled, it'll never ask again, so it might have been enabled by accident sometime in the past.

SMS 2FA often blacklist VOIP and similar systems to avoid abuse. Try receiving SMS 2FA at a Twilio number, for instance – it’s super unreliable. There are virtually no providers where you can reliable receive 2FA via SMS programmatically, with the exception of a handful of companies who use large banks of real SIM cards.
