Ask HN: Virtual phone provider?
3 by tucaz | 2 comments on Hacker News.
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.
