No. That can also be an advantage. I recently found out that an e-SIM costs 60 Sfr for a prepaid mobile phone with one of the biggest network operators. https://www.mi.com/de/support/faq/details/KA-766715/

The Redmi Note 14 5G has NFC capability, although availability may vary by market or region. To check if your device supports NFC, you can go to your phone's settings and look for the NFC option in the connectivity settings.

You can choose what you want. On the official site you can find the standard charger. I took an old one, not many whatts that will save the battery.

The 5G mode can be either NSA (non-standalone) or SA (standalone). NSA utilises existing 4G infrastructures to provide 5G services, while SA uses a standalone 5G infrastructure. Both modes are available in modern 5G devices to support different network environments. The Redmi Note 14 5G supports both NSA and SA networks as shown in the available network properties.
