Firstly, I don't use bestmate or even TXT2000 becuase it doesn't suit me. Second, I need a prepay plan that has not rubbish add ons  to rip peoples money off, also a plan with 0.49c calls and even 0.49c Australia, Canada, Ireland, UK & USA with no contract, would be reliable. The reason is that, I don't just make one or two number calls, i make several calls with different number, so generally bestmate doesn't suit me, and then i don't txt that much so I don't need txt2000. At last, I go over to Aussie very often, so i make number of calls to Aussie.
