hello, i'm looking for the same thing with you but i look for USA or UK.
I find this
https://freezvon.com/ it has an option for USA mobile number, costs $10 for setup and $10 per month, but i don't know if i will be able to use it for verification.
It doesn't have any free trial...
If you find something, please tell me.
I checked the site that you mentioned, investigated it but didn't find any information regarding regular phone numbers. Asked the support about it and they confirmed it by:
"Our company provides only virtual numbers and they can receive massages and calls from real phone numbers.
We don't guarantee receiving sms from payment systems, social networks and internet service as such sms can be blocked by providers."
Also I updated my post and offer 20$ as reward, maybe that will speed the things up.
