hey guys, i kinda need some help... i like went through the hotlink website for quite a while, but i cant seem to get the information i want, anyway, if you guys know, can tell me pls... thnx...

1) is it true that you cant change anymore between sms and talk plan?
2) how to like change to total plan? the only plan change i can find is the hotlink plan...
3) and whats the diff between total plan and hotlink plan other than the flat call rate thingy? is there like a catch to it like a monthly fee or anything?
4) which would you guys recommend? total plan, or hotlink plan?
