Re: which carrier does the windows hd phone 5 work best with??? at&t or tmoblie or net ten
User... Do you mean the Blu Win HD with the 5" screen?
If you get model W510U it has everything you need to get connected on any ATT or T-Mo SIM. Either straight from those carriers or any airtime reseller (mvno) using their towers like Net 10, Go Phone, Lycamobile... I have mine on Straight Talk and it works just fine with an ATT compatible SIM. It is unlocked and will take any SIM.
