Well, it seems the website for mobilecaller isn't up right now. I did call my access number and entered my code and it was all still there, so hopefully the site is just temporarly down.
This is the first time I've not been able to access their site.
As far as calling the U.S. from the UK - we didn't have much luck finding a good phone card. He did have a landline available to him that he was able to set up some sort of calling plan on that ended up being cheaper per minute. Not much help, I know.. Sorry..
Altho, thinking about it, we probably spent more that way too.. we didn't have some nasty lady rudely interrupting our conversations with "YOU HAVE ONE MINUTE REMAINING!" (to which we'd have several polite replies
) so we could just talk on and on and on
Good luck and have a safe trip
