I was overseas and my provider (Cricket) doesn't have roaming so I usually pick up a cheap prepaid SIM locally.

I didn't enable 2FA on Uber but it insisted on sending me a code via SMS (of course, to my inaccessible US number). That was incredibly stupid and shortsighted. Meanwhile, all services that were set up for Authenticator MFA worked just fine over the European carrier's LTE.

I also tend to purchase a prepaid SIM while overseas, and ran into a bunch of issues paying for bills at bars/restaurants using their website or mobile apps, as my credit card was doing a second layer of authentication through Mastercard's Verification and would only send me a code via SMS!

It is crazy that my capitalone mastercard wouldn't allow me to do the validation through my capitalone app!

Next time, use an app like pushbullet that will forward your text messages to you. It's a huge security risk since if pushbullet or whatever gets hacked then the hackers would get all of your access, but for a short term utility like ensuring that you have connectivity it may be well worth it.
