Used a Malaysian number from Matrix sims and was a good decision ---- I traveled to Malaysia with my family in Dec and my dad decided to use Matrix sim card for himself and one for me and my sister as well so that we could all be connected just in case if we decided to explore the place by ourselves. We got our matrix sim cards quickly delivered at door step. The best was CUG calling was free for both the numbers and it worked good in terms of call connectivity. Network coverage was also good. And last but not least, my dad’d intention of saving money on international roaming paid off pretty well. All in all the preference of using Matrix really helped us!
