I have been a Sprint customer since December of 1996 when they were Sprint Spectrum. Have I considered going to another carrier because they were getting phones that Sprint were not getting, thought about it for maybe 5 minutes and tossed it away. Have I had problems over the years that I had to call in, I can count that on 1 hand. Have had data slowdowns, yeah to be expected in a major city, I am just outside DC. Am I looking forward to Network Vision completion? yes but tempering anticipation with patience. I have seen some substitute there cellular data as there home internet and it usually backfires especially if you have AT&T/VZW with tiered data.
