Toll-free SMS is listed at $0.0065 per message on Bandwidth's toll-free product page and $0.007 per message on its general pricing page, so expect a rate in that range. On top of per-message rates, A2P 10DLC traffic incurs mandatory carrier registration and pass-through surcharge fees set by the mobile carriers.
