Abiram I am using a Nothing 2a phone with two SIM cards. I prefer to have the option to choose which SIM to use when making a call. However, after setting this option, it automatically changes to a default SIM after a few minutes.
hrry Abiram hello mate, If you’re experiencing issues I’d log a bug report via settings > system > feedback or, contact support via https://nothing.tech/pages/contact-support as they’re best placed to help you with this.
