This weekend, I will be going on a cruise to Mexico and I am wondering if I would be able to text people in the US with AIM. The people I have in mind are Verizon users and have the unlimited texting (500 free for other providers). If they text me back from their phones on my AIM, what kinds of costs will they incur? Do the texts they send to me (outside US) count as international?
Those that are in the states with a plan with $10 unlimited M2M and 500 out of network domestic who use AIM or any IM will have those messages deducted from their 500 out of network. IM does not count as m2m.
