If anyone is looking for an alternative, I suggest Google Voice, I've been using it since 2012 and it works great (with a couple exceptions):
- US Number for 2FA, no issues with banks or any companies so far
- Free once you port your number
- Free North America calls, free 800 number calls in any country that offers them, including Argentina
- Great for Voicemail
- You can get voicemail transcriptions, MP3s, or both
- Limited Spam
It's limits are:
- Call forwarding to US numbers only
- You have to send out a text or make a call every 3 months to keep it active
- App doesn't work on my phones and never has because it checks if you have an active US number for your SIM card(s), despite it being a VOIP service (i.e. I rarely if ever can get it to "ring" even on my laptop when someone calls, I usually have to make the call which isn't bad for a free service IMO)
