Making this thread for discussion about the new AT&T MVNO Aio Wireless. Curious to see what anybody has to say that's tried them. What kind of speeds you get (also pings), coverage (especially in larger buildings), and whatever else. Had a response from a person in another thread who said they got longer pings (100-200 ms) than normal for AT&T LTE (attributed it to a Aio proxy) so if anybody else has seen the same it would be interesting to know. Also if anyone has used both Aio (or AT&T) and Sprint LTE and can provide some comparison that'd be cool especially since this is a Sprint forum. Also any comments about AT&T's network (HSPA+, LTE, 2G) would be great.
