SIM-This is often inertia from the days of the old button phones, or when you switch from another device where this was the norm. However, keeping contacts on a SIM has a number of significant drawbacks, including a limitation on the number of characters in a name and the inability to store additional data such as an email or address.

When you transfer data to Google Contacts, you get sync between all your devices. If you lose your Poco X3, buy a tablet, or decide to temporarily use another phone, all your numbers will instantly appear on the new device immediately after you enter your login and password.

Managing through Google Contacts and Synchronization

Usually, the system clearly separates sources: SIM and Google.

Once combined and transferred to the cloud, deleting the original record from the SIM card becomes a safe and logical procedure, not leading to data loss.
