wether tmo purposely designed the tmobile @home service to function as an alternate method of international connectivity is unknown to me. a few years ago tmo didnt guarantee functionality of the hotspot@home (thats what it was called a few years ago) service while traveling internationally, mainly because the server that patches your connection from the internet into tmo's network is located in the US, so if your connecting from overseas latency becomes a significant issue. you should call tmo to find out all the details of the service. things may have changed since I last worked with the service. also just incase they don't tell you, it would be a good idea for your daughters to disable their gsm connection while they are using hotspot at home to ensure that they dont accidently connect to an international carriers network and wrack up huge bills. even if they can't use hotspot at home all the time, it can be used to cover the bulk of their non essential communication.
