Mobile IPv6

This page is about native IPv6 support on mobile devices.

At the moment (June 2013) AAISPs data SIM service does not support IPv6 natively due to the carrier not supporting it, but tunnelled IPv6 is possible, and means that IPv6 can be used and IPv6 on a DSL line can even fall over to be tunnelled to 3G in the event of a DSL fault.

Device support

As the modem establishes an IP(v4) PDP context with the network, to do IPv6 the modem would need to support it (or use a full PPP context).

Devices which do/don't support an IPv6 PDP type (there are AT commands to query the modem's capabilities):

Network support

I (met) have tried connecting with a K4505 and an A&A L2TP-handover SIM using a PPP context, but it doesn't work. An IP context gives you a CONNECT response immediately, with a PPP context it sits there for a couple of seconds before returning NO CARRIER.

I see the same results with a Vodafone contract data SIM.
