It's on the roadmap, but we need to integrate with another provider to support them. Most major communications services that verify your number don't mind which country it's from, but we realise there are good use cases for having a number from a specific country.
Is there anyway to test one of your numbers to see if where I plan to use them they are accepted, before buying?
No, we don't offer free trials, as they would be abused. However, you can just rent a number and cancel it immediately if it doesn't work for you -- we charge the rental by the minute so you would only spend a very small amount of money in the case that it didn't work for you.
