I bought a Matrix Sim card for China and was glad i made that choice. The benefit of the customer services being in English to begin with and the possibility of sharing my number with my associates in China before getting there, made it quite easy for me. Am glad that i not even for once did i make a single call to the customer services and the sales rep ensured that my bill was not charged on my card, instead i paid by chq. Really like Matrix for their custom made solutions !! Thanks guys
