I answered this for people already this phone will work for any network AS LONG AS THE NETWORK BANDS ARE COMPATIBLE. So your best bet if it's a GSM based carrier is to look at the Tmobile Moto X it supports the most bands because they have their own bands and then when att trying to buy tmobile fell through a couple years back Att had to give them some of their spectrum so the tmobile moto x supports the most gsm based bands. Tmobile moto x supports I believe 750,800,1200,1700,1800,1900,2100, and 2400 mhz bands don't quote me on that check http://gsmarena.com
to verify. Then search on Google what bands your carriers use and if the numbers match you can use it.
