My friend got the 6030 w/ Tmobile Prepaid. I have had a Nokia 6010 w/ Tmo Prepaid for over a year. His phone is very disappointing. Construction is flimsy: it creaks and squeaks anytime you touch it. The buttons are tiny and challenging to manipulate.Worst of all - his reception is TERRIBLE! When I call him I frequently get his voice mail. His phone frequently will not get a signal. While this could be due to his location, I've held his phone in one hand, and my phone in the other hand. My phone acquires the network without trouble; his phone usually will not. He formerly had Tracfone and had much better reception with a Nokia 1100. I think his 6030 may be defective, and I urge him to return it for a different unit, but he doesn't have his receipt any longer, so he's worried about trying.It's too bad he didn't sign up when they were still using the 6010.
