bro, you are right, it wasn't easy at first.
saw some bros here posting to sell unregistered sim at $50 , personally i felt quite expensive.
later on, heard from friends g area got sell, so went down to buy.
walk from l20 to l8, no one willing to sell, their reply:"don't have"
finally come to 1 stall, after being asked so many questions, to make sure i am not trying to be funny, finally he sold me. M1 unregistered at $26
there after, i will meet up some bro at the booth to buy the card.
there is once, he has no stock, he called another booth owner, and we just go over and buy. no more "don't have" reply
.
