Runescape Pins

If I buy a Runescape Pin using an AT&T cellphone what does it show up on the phone bill? I heard it says "Premium" but I could be wrong.

 

I'm pretty sure it never shows up on the phone bill if you put a different number in the "Number you are calling from" part.

 

If you meant the part on runescape.com, that part is absolutely useless and is just used for recovery purposes.

 

On my phone bill it says Surfpin then the pin I redeemed, but my parents dont know what that means and they don't check it so it's all good

 

Where is it located on the phone bill? Like what section
If you could supply a picture blocking out your information that would be great

 

Mine comes out under the mobile phone section... and I dont use AT&T, I use Telstra the major phone company in Australia...
and I dont have the bill so I cant get a pic, sorry.
