We had done enough research on international sim cards and overall everybody had the same to say about all the options available but still since my husband and i were looking at more economical options, we agreed upon using Matrix International Sim Cards over the others. It was wise decision we made. The network across Belgium was really good and it actually was cost effective. We were quite surpised when we saw a proper itemised bill of Rs 4790/- . Guys its quite the contrary to what ppl have to say !!
