No problem whatsoever. The Presto Printing Mailbox is "portable" in that regard. In fact, we even recommend that Presto users take their Printing Mailboxes with them if they go on an extended vacation (like flying south to a vacation cabin in the winter, for instance). The Presto Printing Mailbox will automatically "hunt" for the best local dial-in number. It does so first by calling into the Presto Service via an 800 number, and then by using the closest local dial-in number (determined through caller ID) from then on.

In the case where the Printing Mailbox has already gone through this "hunt" routine (as in your example), no worries -- it will start the "hunt" all over again from its new location, ending up with the new local number.

Best of all, there is nothing for you, or her, to do. Just plug in the Printing Mailbox to 110 volt power and a phone line, and it will do the rest. It may take a few hours before it has completed it's "hunt" so be patient. But, it will reconnect automously. It doesn't get any easier than that.
