If you are looking for an affordable international sim card, Matrix sim cards are the only option and the only answer. I took their sim & handset for US and the guy explained every detail on the tariff so that when my bill comes i know why the incomings were charged and all. Felt all the relevant information being shared and infact when my bill came, every call was relevantly charged unlike what others told me. Just have to say, i had a pretty decent frst time experience using matrix sim card!! Will definitely try it the next time as well
