I live in Canada, and don't want to turn on my Smartphone in the US because of roaming charge surprises. In March 2012 DH and I bought cheap ($10 each!) Virgin flip phones from Wal Mart with prepaid phone cards. They totally met our needs as far as DH and I being able to locate each other in the parks. For our upcoming trip to WDW I need new prepaid cards -- Can I find them anywhere at WDW? Maybe at Downown Disney? Also, does anyone know if these phones expire in any way? Like I said, the last time I used them was in March 2012. We will be flying out of Buffalo, so it would be possible to get there a bit earlier to head to a US Wal Mart there to sort it out, but if I knew that there were cards at WDW, it would save me a lot of hassle. Thanks -- I tried calling Virgin abut got nowhere and the phones will power up, but I can't use them (even to add $$ on them) from Canada.
