Yes, if your device is dual SIM enabled, you can have 1 plan active on your SIM card and 1 plan active on your eSIM at the same time. This allows you to receive calls and messages to both numbers and select which plan you want to use to call or send text messages or use data.
If you're currently on a call on 1 SIM, any calls to your other SIM will be directed to voicemail.
