Can anyone explain the SMS pins nowadays?

Alright well im starting to sell pins again, simply because I have methods to get numerous phones without getting charged on them.

What is the SMS pin system like nowadays? Some people are telling me that the pins are redeemed for 25 or 35 day memberships, and the prices range.

I just bought a few pins by texting RS to 64337, but on the website it tells me to text HD to 64337. What is the difference? Just the price? Because the HD one costs 11.96 USD or something while RS is the traditional 9.99.

Also, phone companies include cingular and sprint, right?

Thanks

I'm pretty sure HD is the 35 day on, pretty sure the RS is just the regular. You'll be fine.

 

I did HD just the other day, it was 31 days... I got ripped off if you're correct.

 

Well Jagex recently made memberships more expensive (in about august)

So the old "RS" messages get you around 25 days (not sure) and costs the regular ammount of money.

The "HD" messages get you 31 days of membership and costs a bit more.
