I'm trying to understand Ting's coverage map, which has color indicators for the following types of data: Data (=pale yellow), 3g (=bright yellow), 4g Wimax (=purple), and 4g LTE (=fuschia). It's the plain old "Data" category I'm wondering about. What is it, and how is it accessed, and/or what kinds of phones access it and when?
Sprint's own coverage map doesn't have this category. It can't be Edge, since that's just GSM. Is it 1xRTT?
Smart phones--If I turn off 3g and 4g on my Galaxy s2 (or if I'm not in 3g or 4g coverage areas), is there a way I can still access plain old Data on a Galaxy?
Feature phones--What data categories do feature phones use when they deliver emails?
Thanks in advance for any insight you can give me!
