There seem to be horror stories on reddit about Google Voice numbers being terminated for people out of the country too long.

Is there a stable inexpensive phone number service for folks that are outside the US a lot?

I've been looking into Google Voice alternatives, and https://voip.ms/ looks good.

I've been using voip.ms and it is fairly good. I wish the SMS support was a bit better but it does reliable deliver messages to email or SIP. (Large messages are not re-joined though and sending is based off of a code in the subject instead of an email address per-number which could be easily be added to an address book)

I used the Republic Wireless wifi only service for $5/month. Still more expensive than it _needs_ to be, but well worth it.
