I signed up for the T-Mobile 7 day test drive and have been using my phone for a couple of days now. The coverage is decent in my area though not as good as my at&t. I am still trying to decide if it's worth the savings for me to switch. From my calculations, I am only paying $5-8 more per month for my lines on at&t when I factor my corporate discount of 23% from my employer. I called T-Mobile CS tonight to inquire more about the new plans and I was totally unimpressed with the CS rep that I spoke with. I felt like I was calling somebody down at the local pool hall or something, I might as well have because this guy seemed to know very little about the new plans. He informed me that if I sign up before labor day that I could get the 5th line for $20 more and the other 4 would be $100 making 5 lines $120. I questioned him on this since the website mentions 4 lines for $120 but he assured me that I could get 5 lines for $120. Does anyone know if that is correct? He also told me that this plan does not have the ability to add tablets, except to add using standard tablet pricing of $10 for 3GB or something like that, and that I could not use my 15% corp. discount on these plans. As for jump pricing on phones, he said they would need to run my credit first to give me pricing info.
