Is PAC SWC Module necessary?

I have an Eonon branded RK3188 unit - I replaced an older Pioneer system that a previous owner of the car (2005 Jeep Grand Cherokee) had installed - his setup used a PAC SWC module, which the guys who installed my Eonon used as well - was wondering that since the unit itself seems to have wiring specific to the steering wheel function, if this module is necessary at all? I ask because there on the left side SWC, my middle button mirrors another button, is not recognized independently - I had previously installed a different Android Head Unit, and with that one, the buttons functioned properly -

T Mobile M8 could not be activated on Network

Greetings. I have bought a T-mobile M8. I unlocked it and also twrp custom recovery done. Bootloader 3.19. S-ON. My problem is I am trying to use it in Europe but it is not working.. only offline mode. I am a happy h/k Sprint M8 user since 2014 and I have bought this for present, but I can't make it working. Do these unlock codes ( I have found for 9$) would do the trick? If sunshine works, what should I do after that to make it working?

Thank you very much!
