Nothing in particular. More like we were a bit turned off with the daily usage fee M1 has. I guess that is a moot point since my wife does have the "free incoming" turned on with Green. That costs $0.59 a day with Green. The thing that wasn't clear was whether daily usage fee M1 charges is everyday or only on days with activity.
We really didn't have a huge preference with Green over other competition. The reason Green was our first preference is because her other co-worker has used that before and it works. Also, we found out that Green has "free" (no long distance charge, except normal minute fee) calls to USA until end of the year. This way she can use the cellphone to call back to the US without using the expensive hotel phone (or using somewhat complicated call-back mechanism). Other than that, she did find a close 7-11 to her hotel first. So, she bought the Green card versus the other.
Let me know if I can answer anymore questions.
