Free Mobile Surveys

Hey guys, I was wondering if you get charged for any subscription fees (e.g. $2 per text, $10 per month, etc) for mobile surveys where you get the pins even though you hit STOP after you get the pin? Reason is because I did a couple of surveys that charges $2 per text, but I texted STOP to stop the subscription, but I'm not sure if they charged me $2 for the pin number and other text messages they sent since I don't have my bill yet(I have unlimited text btw). Thanks for your help!
