First a note about T-Mobile's customer service: it's fantastic - the best bar none; responsive, never argumentative and always helpful. Unfortunately this phone gave me the opportunity to get to know that department a little too well, but at least the experience wasn't unpleasant.Back to the phone itself, the internal antenna leaves much to be desired. I wouldn't recommend the e715 to anyone who isn't always in an area that has very heavy cell coverage. My husband and daughter have two different model Nokia phones and both have internal antennas but yet they both manage to keep calls longer and make calls in areas where the e715 can't pick up signal. Don't get me wrong there are pros for this phone:- very lightweight weighing in at 3.0 oz- compact size fits almost anywhere- easy to read external display- large, vibrant internal color display- 640x480 resolution camera w/ lots of extras like framing, sepia, b&w;, etc- fairly intuitive, easy to use interface, however I have to warn any Nokia users, it is significantly different and takes some getting used to.The one very large con is the poor reception and lets face it, you can put as many bells and whistles as you want on this thing, its main purpose is still a communication. No signal = no communication = funky gadget but a bad phone.
