The phone reads the phone number off the sim and lists it on this page as well. Heres my issue I have verified that phone will cover the same bands where I am so that should not be an issue. I can not get a signal with this phone with 2 different sims. I made sure I did all the obvious things with the settings, the APN's, flashed different radios, and tried different options is the 4636 menu. Ive used different roms as well...When I go to select or search for my network both options are grayed out.... I can connect to Verizon and I can connect to sprint towers but no Dice on ATT. I am currently on version 4.1.2 and have tried all available radios. Has anyone had success in the new York New Jersrey PA area with using this phone on ATT. If so what is the setup you are using.
The Sprint HTC one has blocked the carrier id's for domestic use aka att. You can however if your s-off you can flash the initial release radio the first radio when the Sprint HTC was released and it will allow you to connect to domestic carriers.
I'm in Ohio so not too far from you and I can pick up T-Mobile and att using the initial release radio, it is the only radio I could get to pick up signal.
Here is the first radio released http://d-h.st/HHD
