IndiaAIFounders — S26 Ultra (Snapdragon) DSDA Data Concurrency via TelephonyNetworkSpecifier

I am researching the modem and RIL (Radio Interface Layer) capabilities of the Galaxy S26 Ultra for a specific networking project. I know standard One UI only routes default internet traffic through one SIM at a time.

However, does the S26 Ultra support concurrent dual cellular data (DSDA Data) if requested programmatically?

If SIM 1 is the default data SIM, and I create a background Android service that explicitly requests the SIM 2 network using:

NetworkRequest.Builder().addTransportType(TRANSPORT_CELLULAR).setNetworkSpecifier(TelephonyNetworkSpecifier(SIM2_SUB_ID))

Will the ConnectivityManager return a valid Network object for SIM 2?

More importantly, if it does, will binding a socket to this SIM 2 network drop the active PDP context / default internet connection of SIM 1, or can both TCP streams flow simultaneously?

Has anyone tested concurrent dual-data routing on the S26 Ultra's modem?
