Like the title says, I recently purchased a list of phone numbers of target customers. I want to do some outreach to them, but since it's international I figured I will have to use Whatsapp. But whatsapp for business charges ridiculous amounts of money per message making it impractical to hit...
I mean business, which works great in your country, but when you were abroad, you have not seen it.
I'll go first: It's cash terminals, where you can topup balance of phone or any other thing. It's like ATM but vise versa.
