Used a matrix sim card for the very first time for Malaysia. Since I had gone for work, I had the opportunity of using a matrix sim card that my company had procured for me. That made my work and travel very easy. My staff already was informed what number I would be on. So contacting them once I landed was easy. Also I had my mails configured on that number, hence there was no scope of missing out on work as well. Overall i had a smooth ride with matrix. The work didn’t suffer, the network was good. Was worth using it very honestly.
