Look into the Google Voice app. You can get a free US number that works with both SMS and calls. It routes calls through Google's VOIP I believe.

I use it as a burner for any website that requires a phone number. I figure it will be easy enough to change my burner phone number if it gets leaked to some shady DB.

And then you run into many services that right out refuse VOIP numbers, some of them fairly essential or near essential.

I don't use those services. I change the SIM card in my phone (and its direct number) several times per year, it would make use of those services impossible.

Last time I looked, you can't sign up and use Google and Google Voice without verifying that you're a real person via SMS.

But pretty much no where else in the world -- including Spain. So this is practical how for anyone outside if the US?

Substitute DIDww for Google Voice, then.
