A54 Dual Sim - How to turn off data for 1 SIM only

[Nomad64]

Under Android 14 and One UI 6 how do I turn data off for 1 SIM only while leaving both phone numbers active?

There appears only to be one overall option for Data Roaming now rather then the per SIM options in older Android versions.

Was it always like this in A54 or did chnage update abrecent update?

In Settings > Connections > SIM Manager, you should be able to select preferred SIM for data and in Settings > Connections > Mobile networks, you should be able to turn off/on Data Roaming per SIM.

Open your phone's Settings app.

Tap Network & internet. Internet.

Next to your carrier, tap Settings .

Turn Mobile data on or off.

Yep - but a single 'data on or off' for all networks together doesn't solve the problem of turning data off of the expensive ones.
