CPA w/ SMS Traffic ?

Hi, is there anyone that tried SMS spam to canada/USA numbers with a CPA offer? i am new to CPA/sweepstakes this but have a lot of experience in SMS marketing, been doing it for a few years and its high converting for any online business.
a few days ago, someone asked me to send 20.000 SMS to canadian numbers, it was a "Win iphone for 1$" link
he was so happy with the result he wanted to pay me x2 for the same job if i can send more.
i can send 50 to 100k SMS per day and extract valid numbers list from websites, is anyone ever tried this ?

How much do you think he converted ? i had 1200 "STOP" textback messages and like 2500 replies (SMS) on 20k

How do you manage to send those sms bro?

Which API service you used and did you create a LP while sending messages?
