Right, that makes sense. It's not the right fit for every business idea. If you could find yourself a 5-10 beta customers, perhaps launching to them before billing is ready might work? You could even perhaps set a cap on how many SMS messages they can send per day or week. That would keep your costs low while still getting you some feedback. You should of course do whatever is best for your product. I've just learned from experience that launching as soon as you can is great, because you'll often find that many of your assumptions about how and why people will use your product don't match how they actually use it.
