Switching from AT&T postpaid to GoPhone--any possible snags with my plan?

[anex99]

I just started looking into StraightTalk. Their coverage map (Android vs. non-Android) left me puzzled/assuming and their website is certainly lacking in detail... I'm happy to ask ST questions on that board, if necessary, but do you know:
1. Can I use a 4G or HSPA+ device on ST for talking, texting & data?
2. What does the "non-Android" coverage map really mean? If I'm using my Android and leave the Android coverage area, do I get no connection/a slower connection/no data or something else?

For ST,

Android coverage = Sprint
non-Android = Verizon
BYOD SIM = ATT or T-Mobile

I really think you should just go to Straight Talk and save the $5 a month unless you need the Mexico/Canada roaming.

I can happily do without Mexico/Canada roaming, so I've just ordered the ST SIM card. I guess I learned my lesson on this one: I thought I'd read every word of GoPhone's website & asked all of the right questions, but never thought that the phone I was using would present a problem. (And it seems to be a source of confusion even within the company, since two phone reps were aware both of my existing phone and which phone I intended to purchase, and neither flagged it as a potential problem.) On the flip side, the reason I immediately ruled out StraightTalk was because their website coverage map wasn't updated and seemed to indicate much less coverage then they actually offer. Had their materials been updated, I would have considered them from the outset.

I really appreciate all of your help! Thanks to all of you.
