If you aren't happy with it then switch to a pre-paid provider. There are many options now that are just as good as AT&T and cost much less. Buy a Nexus 4 and get T-Mobile's pre-paid plan for $45 a month including data.
T-Mobile isn't everywhere. Doesn't work here. ST does work great on either CDMA (VZ) or GSM (at&t).
