As a phone for talking, Puretalk was as good as AT&T. Same for texting. But for data, it was horrible, as in non-existent. So if you need data, stay away. Otherwise, it should be ok for you.
That’s because they’re an MVNO using the AT&T network. As an MVNO, their users get their data throttled or even be kicked off towers if higher ranked users need it. MVNO users are the lowest on the totem pole. See my post above.
