Automatic selection of SIM card (dual SIM) according to addressbook groups or contacts
Summary
On Dual Sim phone, offer the possibility to set one of the two SIM card to specific addressbook group or contact.
Description
Who will use the new feature?
Dual SIM phone owners like Fairphone owners
What is the target of the new feature for this user?
Once the settings done, the user will very easily be able to send a text message or call a contact with the correct SIM card automatically.
Why this user would like to use this feature?
Making a phone call and send a text will be easier and the risk of mistake will be reduce.
Examples
Right now, when a user wants to call, the user should select which SIM card to use. That makes one useless step in most cases. The user want to call a contact for work, it should call directly with the "work" SIM card. The user want to call a family member, it should call directly using the private SIM card. Same idea with text messaging. How often a user will send a message for work with the SIM 1 instead of SIM 2 and, unfortunately, give unwillingly his/her private number to a working contact...
Having the possibility to link one SIM card to some contacts or group of contact and the other SIM card to other contacts or group of contacts would make the usage more straightforward and will reduce mistakes.
It could also remember the choice made when we call or send a message for the first time to a new contact (with the possibility to change that afterwards)
Reflection
Something like this app https://play.google.com/store/apps/details?id=com.steffen_b.multisimselector&hl=en_US&gl=US but integrated into /e/ settings and not only for outgoing phone calls but also for text messaging.
