I had to change carriers a couple of months ago because they left me high and dry thousands of miles from home. Now I just came back from the same exact location (which means the same carriers, cell towers, etc.) and using the same phone (now unlocked and ported to Koodo) and I must say it simply worked the whole time I was there and I was pleasantly surprised to get a friendly text message from Koodo as soon as I turned on my phone, "Welcome to the Caribbean" and advising me of the roaming rates. While I do understand that $2.50/min is pretty steep it's competitive with other Canadian carriers under similar circumstances and I only need to be able to receive a quick emergency call, having the caller call me back on a nearby land line if the call needs to last more than a minute or two. So I am very pleased with Koodo.
