Also with sim removed you can make calls but no data access.
Man, you're wrong.. there few manipulations to unlock cdma and flash number to phone, but it works only 1x... in my Country(Ukraine)... because we have not sprint(one of EvDo pararameter - unflashing.. sprint locked EVDO... we are investigating it... where it can be in rom)
so, to put into the diag mode, you need find MSL(SPC), unlock bootloader, boot with custom recovery (without flashing recovery if you want) and then install superSU...
boot with custom boot(it included diag ports)
next in adb switch usb settings from mtp to diag(you can find it in XDA)
after it your OS will install drivers for COM port and BINGO!!! you will see your nexus 5 on ports and can flash number over DFS or qpst or else, which you like more.
