Apparently not enough people were attracted to a phone service with a misspelled name despite the underlying network being Verizon's. Maximum PC goes on to say, "The Q&A goes on to explain that users must pay their final bills or will be turned over to a collection agency — kindly enough Amp'd explains that 'no early termination fee will be assessed.'" When looking on the Q&A on Amp'd's site, one sees something relating to their claim of CDMA phone portability in addition to the [already] legally mandated number portability. Only time will tell whether this is accurate or not suggesting that Amp'd phones might be usable, to varying degrees, on Verizon (most likely) and Sprint (less likely) as well as other smaller niche CDMA carriers (despite the seemingly rather small selection of phones)."
