Dual Stack IPv6 Support on iPhones

Dear Apple,

Greetings from Bhutan!

I work as a Packet Core Engineer in one of the Telecom Service provider in Bhutan. We have recently launched and commissioned Dual Stack IPv6 in our Cellular Network. Because of the fact that Apple doesn't allow devices in this region to activate Dual stack PDP automatically, we are not able to progress any further with IPv6 growth in the country.

I would appreciate if Apple could provide us an immediate support on this issue. We would like to have all Apple devices in Bhutan to support Dual stack PDP type.

Looking forward to your support!
