If you would like to receive calls to your known local swiss number, redirect it for few monthes

to virtual swiss number : https://zadarma.com/en/tariffs/numbers/switzerland/  - 2 euro per month.

And you will be able to receive calls via mobile internet. So everybody can call to you  by using known number.

For calling back when your would like if receiver see you swiss number you should use VoIp client

what is able to use number from your SIM card. I'm using  https://play.google.com/store/apps/details?id=com.nettia&hl=en

So basically you can leave your local SIM at home and able to receive/dial number by using it.

For able to send and receive SMSes by using your number, your need to have application like this : https://play.google.com/store/apps/details?id=com.rivetlabs.sms&hl=en

So you can have full remote control/usage of your swiss SIM even you keep it at home.

Some real international SIM has predicatble tariffs if you really would like to call in emergency case but better to have mobile internet and use it for in/out calls as cheap solution.
