I am wondering what would be my best option for using data on my telus nexus s while at WDW. I plan to use my phone mostly to check my email and a few disney apps for wait times and gps maps. Getting a US data plan through telus is way too expensive. I'd probably wouldn't need more than a 500mb plan. Since my phone is not locked I understand that you can buy an at&t or t-mobile sim card from ebay and then buy a "pay as you go" type refill card when you get there. Has anyone tried this? How did it work out for you? Which one would you recommend, AT&T or T-mobile? Are there any stores in the Orlando airport that would sell these refill cards. I won't be renting a car and would like to be able to get a refill card without having to go off Disney property if necessary. Any info would be greatly appreciated.
