Hello, I am currently with Sprint, but need to switch service because I am having issues with Sprint that they cannot resolve to my satisfaction. Is there anyone out there that lives near or in Commack, Long Island, New York that gets great cellphone service in their home? If so, what service provider do you use and how are their customer service reps when needed? I am thinking about switching to T-Mobile or AT&T because they seem to offer phones that will work world-wide and I travel to Spain quite often to visit family. Note that Sprint works well in my home and I have had Verizon prior which did not work as well in my home. So, I would like to hear specifically from T-Mobile or AT&T users. Thanks, Mike.
