What they did
Because each phone number cost money on Twilio (on the founder's credit card), Burner launched as a $1.99 paid download including a free number for about seven days. Users then bought consumable credit packs (3, 8, 15 or 25 credits) to extend or add numbers. Prices were set so that if a user used every text and call minute allocated, the company broke exactly even on Twilio costs after Apple's cut; any unused allowance (breakage) was profit.
What happened
~$50K revenue on the first day; later replaced by a free download after the angel round.

In their words
Sub Club by RevenueCat · Pivots, Funding, and Building Apps That Last – Greg Cohn, Burner“You could buy three, eight, 15 or 25 credits for different price points and then different configurations of phone numbers to extend them.”
“And we priced it out so that we would basically, if a user used every bit of what they were allocated in terms of texts and call minutes that we would... And after Apple got their cut, we would break exactly even on the Twilio costs. And then anything that a user didn't use was profit, basically.”
