On basic tasks, like sending a tweet or posting a status update, all the carriers were able to complete 100 percent of the tasks attempted. For the average visitors' needs, AT&T performed the best throughout the park for tasks like clicking on a link, downloading an image or map or even downloading a song. It was also the top network for any heavy streaming tasks like watching YouTube or Netflix. AT&T and Verizon tied for number 1 in terms of small tasks in line with making a status update (minus the photo/video). Depending on where mobile customers are in the park, when posting a selfie, T-Mobile customers may experience some hiccups; for example in Frontierland the carrier completed just 93 percent of the attempted tasks tested. For park goers looking to stream video, those on Sprint may struggle, as the operator was able to complete just 94 percent and 95 percent of these types of tasks tested in Adventureland and Frontierland respectively.
GWS tested a range of key indicators for mobile performance in developing these rankings – including download speed, upload speed and task success reliability.
