It really depends on how many calls you make and how much you want to spend.
Thanks for the info!
I dont actually have a US SIM, I only have these GSM phones for Europe (use CMDA here). I was trying to avoid shelling out $30 / phone / country....
I might just get one French and one Spanish SIM and tell my folks to buy their own if they need to be in touch or they can have people call me.
