No. Only you can sign in to your Simur account on your phone, just like with other banking, messaging or security app. This means you can't add more than one account on the same device.
If you want to use the app on a new phone you have the option to remove your device via Simur Studio:
- Click on your name at the bottom left of the screen > Click on Login history.
- In the Used devices tab > Click log out and your device will be removed.
