Was an AT&T customer for years, back when it was Cingular. I left after they throttled my unlimited data plan from Oct '11 - Feb '12 (never went over 2GB's a mo). Now on a VZW family share plan but not been happy (travel overseas a lot, AT&T has a better international program/rates and other issues). I'm considering switching, but am torn. VZW: Pro's: VoLTE Better LTE coverage Con's: Horrible International Rates/Plans VoLTE speeds seem to be slower than 3G for many (still early though) Terrible Customer Service Tons of "extra's" popping up AT&T: Pro's: GSM Voice+Data - 4G, not LTE, but seems faster than VZW's VoLTE Best International Plans Con's: Abysmal LTE coverage I've found both carriers to be fairly equal with dropped calls, my concerns are international rates, VoLTE on VZW, AT&T's LTE commitment. Thoughts?
