No it's not. In the US it's available from Verizon and Sprint as the LTE version (not completely compatible with the HSPA version) and there is no device available from AT&T or T-Mobile. You can buy an unlocked device directly from Google, but there is no subsidized version available for AT&T or T-Mobile customers. I bought my HSPA version unlocked in the Netherlands.
