I switched from ATT to verizon just this year, im willing to pay a bit more not always ending calls or not being able to get on the internet. My verizon air card also is so much better then anything ATT had to offer. When traveling I could not get signal across most parts of new mexico, arizona, parts of california I was in and many places in ohio, kentucky, TN, GA it sucked . Never had any issues with customer services from ATT , they both seem to be the same in my opinion.
