Ask HN: Virtual phone provider?

Hi!

I'm a Brazilian national living outside of Brazil and I'd like to have a cell phone number there to register with local business and services that require phone validation.

I know I can use Twillio for that, but is there any other reliable and trustworthy services out there?

This is very important since once you establish a phone number tied to a business account of some sort and you lose that number it becomes a huge problem.
