Dual SIM: Disable telephony features on second SIM I have a Samsung Galaxy S Duos 2 (GT-S7582) with two SIMs. I'd like to use one of those SIMs for everything telephony related, the other SIM for everything data related. I managed to set the first card to be the default SIM for outgoing calls, and I deleted the APN for the first card so that only the second SIM is used for data.

However, I still receive calls for the number of the second SIM. I also get the choice to call using the second SIM, which I do not want.

How can I disable receiving calls from the second SIM? How can I fix telephony/data even harder to the individual SIMs?

Android version: 4.2.2

EDIT: As a first workaround, I disabled the default ringtone for the second SIM. This way only the display lights up, which is easy to ignore.
You can achieve this by applying call barring on the SIM.

Although I know this is a different Andriod version, I am sure you will find something similar to this on my OnePlus 2.


  Phone app > Settings > Call settings > SIM 2 > Call barring > Incoming call barring
