Premium rate voice services have a 15 prefix (e.g. 1515 or 1530) and premium rate text services are five digit short codes beginning with the number 5 (e.g. 57XXX). Calls and texts to PRS typically cost more than ordinary telephone calls/texts depending on the prefix number or short-code. Check the cost of calling or texting PRS from your phone with your own phone company (landline, mobile or cable) as they may charge an additional amount to the advertised rate.
