Depending on your cellular plan, sending a text message to an SMS short number usually costs conventional messaging fees from your mobile carrier.

Customers must understand the text messaging pricing regulations of their cell carrier and are informed of any potential costs related to using short codes. It is imperative for businesses that use shortcodes to clearly disclose any associated prices to customers in order to maintain transparency and prevent unforeseen fees.
