Handovers of connections between subscriptions

An apparatus for wireless communication at a user equipment (UE), comprising:

• a memory;
• and
• one or more processors, coupled to the memory, configured to:
• start, at a default data subscription (DDS) of the UE, a timer associated with a non-Third Generation Partnership Project (non-3GPP) tunnel over a cellular network based at least in part on a DDS switching at the UE;
• determine, at the DDS, that the non-3GPP tunnel over the cellular network is not available prior to an expiry of the timer;
• and
• perform a UE fallback procedure for a non-3GPP tunnel over data connection of the UE based at least in part on the DDS switching at the UE and the non-3GPP tunnel over the cellular network not being available prior to the expiry of the timer.

A method of wireless communication performed by a user equipment (UE), comprising:

• starting, at a default data subscription (DDS) of the UE, a timer associated with a non-Third Generation Partnership Project (non-3GPP) tunnel over a cellular network based at least in part on a DDS switching at the UE;
• determining, at the DDS, that the non-3GPP tunnel over the cellular network is available prior to an expiry of the timer;
• and
• performing a handover of a non-3GPP tunnel over data connection to the DDS based at least in part on the DDS switching at the UE and the non-3GPP tunnel over the cellular network being available prior to the expiry of the timer.
