For have fixed number in Austria or other EU country you can buy it here  : https://zadarma.com/en/tariffs/numbers/austria/

As usualy it cost 2€ per month. After that you need just "data connection" for able to receive calls everywhere.

Or redirect it to any normal number if no data connection. After that you can freely change SIM. I'm using DoubleSIM android phone where second SIM is used for have data while traveling. For limit access of other application to internet - opera MAX VPN can be used for disable one by one if need. For cheap calls everywhere with any own number https://play.google.com/store/apps/details?id=com.nettia&hl=en
