IPv6 Cell Phones

Internet Protocol version 6 (IPv6) is supported on cell phones running:

Android 5.0 or later,
Apple iOS 4.1 or later, and
Microsoft Windows 10 Mobile or later

(and some older operating systems such as:

Microsoft Windows Phone 7, 8, and 8.1,
Symbian v7, and
Blackberry 10). 

Cell phones running Android 4.3 or later come with the 464xlat (a widely supported IPv6 transition mechanism) built-in, although support for Dynamic Host Configuration Protocol for IPv6 (DHCPv6) is still missing. Cell phones running Microsoft Windows Phone 8.1 and Microsoft Windows 10 Mobile or later even come with 464xlat and DHCPv6 built-in.

All apps for Apple iOS 9 (or later) submitted to Apple's App Store Social Networking web page must be compatible with IPv6 DNS64/NAT64 networks

Whether IPv6 on a particular device is enabled and which interface(s) support IPv6 (Wi-Fi or cellular or both) is determined by the individual wireless carrier.

IPv6 Support by US Wireless Carriers

Two United States (US) wireless carriers have deployed IPv6 across their wireless networks:

T-Mobile USA, Inc. and 
Cellco Partnership d/b/a Verizon Wireless (a subsidiary of Verizon Communications, Inc.).

Two US wireless carriers are actively deploying IPv6 across their wireless networks:.

Sprint Corp. (Sprint Corp. and T-Mobile USA, Inc. are in the process of merging. The resulting company 
    will be called T-Mobile USA, Inc.), and
AT&T Wireless (also known as AT&T Mobility LLC, previously known as Cingular Wireless and BellSouth).
