Have you tried smapva?
If not yet check them first you can rent a number that could send and receive SMS and they also accept Bitcoin as payment.
I have used smspva before for sms verification. I had no idea that one can also send sms using the rented numbers which OP is looking for
Is that the same as
http://smspva.com?I tried to log in through the beta link, but It returns an error of the wrong Username or password.
