@cmikec it wasn't just split tests on the messaging. if you signed up last week you ONLY got texts telling you to sign up to a payment plan. If you sign up today then it offers you the paid version OR the free version
That's still split testing of the messaging... in that one message gives different information about their services than the other. Different information being leaving out the free option. Clearly they wanted to see if a higher % signed up to the paid option depending on whether the customer knew about the availability of a free option.
