If you are looking for convenience and good services, matrix sims cards are a definitely good option. I was traveling to Calgary for a vacation and the only international sim card providers who were ready to give me a sim card on such a short notice was matrix sims. Really thankful for them for this. I used their services very conveniently throughout the span of 25 days and not even once I had issues with the network or any other thing. And since I was on a per day rental plan I knew close to how much wuld my bill be. What I really liked about Matrix sims is that they deliver as promised and everything is detailed out in their bills. For me its always a good choice for traveling and I always recommend their services to everyone tht I know of J
