I've had AT&T for many years now, but thinking about jumping to Verizon for the following reasons: 1. Sick of congested network non-performance with AT&T 3G. In Davis Sq especially and in many densely populated Boston areas, I get a very strong signal, but no actual data coming thru (or very slow). 2. Spotty data coverage by AT&T. Streaming music over my phone while driving through some of the burbs or the New Hampshire areas, I get data drop-outs and music stops. I'd rather have slower data, but more consistent coverage. I don't need really fast data to stream music, for example. 3. Verizon seems to have least basic data in more remote places than AT&T. Going up to the White Mountains area in NH, many of my Verizon friends seem to have coverage while I don't. 4. No more 2G/EDGE GSM amplifier interference noise when I'm in a non-3G (remote) area! BUT, when switching to Verizon, what am I stepping into: 1. Poor customer service-- can't be much worse than AT&T! 2. Are there funky CDMA-related limitations, such as not being able to surf & talk? (Though that's fixed with LTE?) 3. Anything else that's Verizon-nasty?
