Answer
Yes, they will be charged according to their mobile texting plan. Subscribers who pay a monthly charge for unlimited two-way texting will not be charged extra for texting to a toll-free number, but other subscribers may be charged per text sent or received.
Calls to toll free numbers, on the other hand, are always free for the callers.
