Can I use the empty SIM card slot on my dual SIM phone for other purposes?

[Guest Shahmatt]

I have the Xiaomi Redmi Note Dual SIM phone. For the time being, as I'm not traveling, I've got just the one SIM card slot active. The other SIM slot's just lying there empty and unused.

 

I wondered if it was possible to make use of it for some other purpose. Are there SIM cards out there that can do other specific stuff: e.g - act as a NFC transmitter/receiver unit or something similar?

 

Just a question that popped in my head. Probably a dead end. But thought I'd throw it out there anyway.

Sorry, i guess not. Near heard that it would be used as NFC transmitter or anything else. The slots are only designed for SIM card. And you can also have 2 numbers if you want later.

I remember back in the WM days there was talk about adding memory to SIM cards so they would be a SIM and storage at the same time with ideas of a whopping 64mb lol, never did really take off as such especially as we are now in the GB era and fast approaching the TB range.
